3M StiKit 236U Gold P80 5-inch Disc Roll – 100 Discs for Aerospace Material Removal

3M StiKit 236U Gold P80 Grit 5-inch Disc Roll provides 100 PSA-backed coated abrasive discs for high-efficiency material removal and surface preparation in aerospace sanding operations. The P80 medium grit provides aggressive material removal — leveling surfaces, removing existing coatings, shaping and contouring — in the initial stages of aerospace surface preparation sequences that proceed through progressively finer grits. The 5-inch disc diameter matches 5-inch orbital and random orbital sander tools used alongside the common 6-inch format for different work area sizes and tool preferences.

The gold anti-loading treatment distinguishes 3M’s Gold series — the zinc stearate or equivalent anti-loading compound applied to the abrasive surface resists the adhesion of sanded material to the disc, maintaining open abrasive valleys for effective cutting throughout the disc’s useful life. Anti-loading treatment is particularly effective at P80 grit when sanding aluminum alloys (aerospace’s primary structural material) which generate soft aluminum oxide swarf that readily loads conventional aluminum oxide abrasives without anti-loading protection.

The 100-disc StiKit roll format provides maximum production efficiency for high-volume aerospace sanding operations — the continuous roll dispenser format allows one-handed disc peel-and-apply changes, minimizing the time spent on disc changes during intensive material removal operations on aircraft fuselage and component surfaces.

Technical Information

3M StiKit 236U Gold uses aluminum oxide mineral on a C-weight paper backing with PSA adhesive on the reverse and gold anti-loading compound on the abrasive surface. At P80 grit, the disc provides a cut rate appropriate for material removal, leveling, and paint stripping preparation — removing significant surface material per pass to efficiently reduce surface irregularities or existing coating thickness. The anti-loading treatment maintains this high cut rate through more passes than uncoated discs before loading reduces efficiency.

P80 grit is typically one of the first grits in a multi-stage sanding sequence for aircraft surface preparation — P80 establishes the surface condition and removes bulk material, followed by P120-P180 to reduce the P80 scratch depth, then P240-P320 for surface finishing, and finally P400+ for pre-coating preparation. The choice of starting grit depends on the initial condition of the surface being prepared — heavily contaminated or damaged surfaces may require P80 start, while lightly oxidized surfaces in good condition may begin at P120 or finer.

Apply StiKit discs to a compatible 5-inch PSA backing pad on an orbital or random orbital sander. P80 grit requires moderate pressure for effective material removal — too light pressure under-engages the coarse abrasive, while too heavy pressure causes rapid disc loading and generates excess heat. Change discs promptly when material removal rate drops rather than increasing pressure to compensate.

Why Choose?

P80 Aggressive Grit — Effective material removal and leveling
Gold Anti-Loading — Maintains cut rate on aluminum aerospace surfaces
StiKit Roll Format — Fast PSA disc changes for production sanding
5-inch Format — Matches 5-inch orbital sander tools
100 Discs per Roll — Maximum-volume supply for production operations

Applications

StiKit 236U Gold P80 5-inch discs are used for material removal, leveling, surface preparation, and initial sanding operations on aircraft surfaces and components in aerospace body shop and paint preparation operations.

Q: Why use P80 instead of a finer starting grit?
A: P80 provides the fastest material removal for initial leveling of surfaces with significant irregularities or existing coatings to remove. For lightly damaged surfaces in good condition, starting at P120 or finer saves sanding steps by avoiding the deeper scratch pattern that P80 creates.

Q: How many discs in a roll?
A: Each roll contains 100 StiKit 236U Gold P80 5-inch Discs.

3M Scotch-Brite Roloc 17186 Gray 3 Inch 2A Medium Aluminum Oxide EXL Unitized Wheel – 10/Carton

admin — Mon, 02 Mar 2026 08:43:58 +0000

3M Scotch-Brite EXL Roloc 17186 Gray 3in 2A Medium Unitized Wheel – 10/Carton for Aerospace Finishing

3M Scotch-Brite EXL 17186 is a Roloc-mounted unitized wheel — a compressed, dense non-woven abrasive wheel that combines the conformability of non-woven construction with the rigidity and thickness of a wheel form factor for edge blending, radius finishing, deburring, and surface conditioning on aircraft components. The 3-inch diameter with Roloc attachment mounts directly on die grinders for flexible application in aerospace maintenance and manufacturing.

The EXL (Extra Life) designation indicates 3M’s higher-density non-woven construction that provides significantly longer wheel life than standard unitized wheels — the denser mineral loading and fiber construction in EXL wheels maintains cutting performance further into wheel life before wheel wear reduces the wheel diameter below useful working size. The 2A Medium grade provides a moderate cutting and finishing action — more aggressive than fine grades for efficient surface conditioning while producing a finer surface than coarse grades.

The 10-carton pack provides a production supply for aerospace MRO shops that use unitized wheels for edge radius blending, deburring machined parts, removing sharp edges from structural components, and surface conditioning operations on aircraft hardware and components. Unitized wheels are particularly valuable for edge work where the wheel’s thickness and rigidity maintains consistent edge contact across the full wheel face for uniform edge treatment.

Industry	Aerospace, Aviation MRO, Aircraft Manufacturing

Technical Information

3M Scotch-Brite EXL unitized wheels use a compressed, densified non-woven web construction — the web layers are compressed and bonded into a solid wheel form that provides significantly more rigidity and consistency than loose non-woven pads. The higher density of EXL construction concentrates more abrasive mineral per unit volume compared to standard unitized wheels, providing both the longer life and the more consistent cutting action that distinguishes EXL wheels from standard grade unitized products.

Unitized wheels are particularly effective for edge blending and deburring operations because the wheel’s thickness provides a wide, consistent edge-contact face that blankets the workpiece edge uniformly, producing a smooth, consistent radius rather than the irregular result that comes from hand-applied abrasive pads trying to maintain consistent edge contact. The Roloc attachment system provides the rapid disc change capability important in production deburring and edge conditioning operations where multiple wheel types and grades are used.

Mount on a 3-inch Roloc disc pad on a die grinder. Operate within the wheel’s rated RPM range. Apply moderate, consistent pressure — excessive pressure on unitized wheels compresses the wheel face and reduces its cutting consistency. Use wheel edge contact for deburring and edge blending; use wheel face for surface conditioning operations.

Why Choose?

EXL Extended Life — Higher density for longer wheel life
Unitized Construction — Rigid, consistent wheel for edge blending
Roloc Quick-Change — Fast mounting on die grinder
2A Medium Grade — Balanced conditioning and surface finish
10-Carton Supply — Production quantity for MRO operations

Applications

Scotch-Brite EXL Roloc 17186 unitized wheels are used for deburring machined aerospace components, edge radius blending on structural parts, removing burrs and sharp edges from fastener holes, and surface conditioning of aircraft hardware during manufacturing and MRO operations.

Frequently Asked Questions

3M 051131-00973 Hookit 216U Gold 6 Inch P400 Grit Abrasive Disc – Carton of 100

admin — Mon, 02 Mar 2026 08:43:58 +0000

3M Hookit 216U Gold P400 6-inch Abrasive Disc – Carton of 100 for Aerospace Fine Sanding

3M Hookit 216U Gold P400 Grit Abrasive Disc is a hook-and-loop (Hookit) backed coated abrasive disc providing fine P400 grit surface finishing for aerospace painting and refinishing operations. The Hookit hook-and-loop attachment system provides fast disc changes on compatible hook-faced backing pads — press to attach, pull to remove — enabling efficient disc changes during multi-grit finishing sequences without tools or adhesive. The gold color and 216U product designation identify the aluminum oxide mineral and anti-loading treatment that characterize 3M’s Gold series of coated abrasive products.

P400 fine grit is specifically suited for final finish sanding operations in aerospace paint systems — removing P320 or P360 scratch marks, leveling fine surface texture, and preparing the surface for sealer or clear coat application. In aircraft refinishing, the final sanding grit before topcoat application critically determines the surface smoothness under the topcoat and the amount of finish polishing required after painting — P400 provides a sufficiently fine scratch pattern for high-quality aerospace finish results when followed by correctly formulated topcoat.

The carton of 100 discs provides a substantial production supply for aircraft paint shops and MRO finishing operations that perform multi-step fine sanding sequences. The Hookit system’s fast disc change capability minimizes disc change time during intensive finishing operations where P400 discs are consumed at high rate during final surface preparation on large aircraft components and panels.

Technical Information

3M Hookit 216U Gold uses aluminum oxide mineral on a paper backing with a hook-and-loop (hook) interface on the reverse for attachment to Hookit-faced disc pads. The gold anti-loading treatment on the abrasive surface resists clogging during fine sanding — particularly important at P400 grit where the very fine abrasive valleys load more quickly than coarser grades with the material being sanded. Anti-loading treatment significantly extends effective P400 disc life in production finishing operations.

P400 grit provides approximately 35-40 micron scratch depth on the sanded surface — fine enough for the topcoat film to fully bridge and level the scratch pattern in high-quality aerospace finish systems, while still providing sufficient abrasive action to level minor surface irregularities and remove the coarser scratch marks from previous sanding steps. For the finest aerospace finishes, follow P400 machine sanding with P600 hand block sanding to further reduce scratch depth before final topcoat application.

Use Hookit 216U Gold on a 6-inch Hookit-faced backing pad on an orbital or random orbital sander. Apply light, consistent pressure at P400 grit — excessive pressure at fine grits causes rapid disc loading and reduces cut rate. Change discs when loading reduces cutting efficiency rather than increasing pressure to compensate — worn loaded discs at fine grits produce heat and glazing rather than cutting action.

Why Choose?

Hookit Hook-and-Loop System — Fast, clean disc changes
P400 Fine Grit — Final finish sanding and scratch refinement
Gold Anti-Loading Treatment — Extended disc life in fine sanding
Carton of 100 — Production supply for aircraft paint shops
3M Gold Quality — Premium coated abrasive for aerospace finishing

Applications

Hookit 216U Gold P400 discs are used for final finish sanding in aircraft refinishing sequences — removing coarser grit scratch marks, leveling fine surface irregularities, and preparing aircraft surfaces for sealer and topcoat application in aerospace paint and refinishing operations.

Frequently Asked Questions

3M Scotch-Brite SI-Dr Roloc 3in Coarse SL Surface Conditioning Disc – Carton of 4

3M Scotch-Brite SI-Dr Coarse SL Surface Conditioning Disc is a Roloc-mounted non-woven abrasive disc for aggressive surface conditioning, corrosion removal, and heavy de-glossing operations with die grinders. The SI-Dr designation indicates silicon carbide (SI) abrasive mineral in a durable (Dr) disc construction, while the Coarse grade provides aggressive cutting action for operations requiring significant material removal or heavy surface conditioning in a quick-change die grinder format.

The coarse grade is appropriate for initial surface preparation steps, removing existing coatings, corrosion removal, and de-glossing heavily contaminated or poorly adherent existing finishes on aircraft surfaces where Very Fine and Ultra-Fine grade non-woven discs would require excessive passes to achieve the required surface condition. Coarse grade Scotch-Brite provides faster surface preparation with more aggressive de-glossing and contamination removal while still maintaining the non-gouging, conformable characteristics of non-woven construction.

The carton of 4 provides a small working supply for targeted use on repair areas, specific surface conditioning operations, and die grinder-based MRO surface preparation tasks where only a few discs are required to complete the work. The Roloc attachment allows the coarse SI-Dr disc to be rapidly changed with finer grade discs as the surface preparation progresses through the required preparation sequence.

Technical Information

3M Scotch-Brite SI-Dr Surface Conditioning Discs use silicon carbide abrasive mineral in a non-woven fiber construction optimized for the more aggressive cutting demands of coarse grade surface conditioning. Silicon carbide is a harder, sharper mineral than aluminum oxide, providing more aggressive initial cutting action on hard, abrasion-resistant surfaces — particularly effective for initial de-glossing of hard aerospace coatings, corrosion-hardened surfaces, and surface scale removal from steel structural components.

The SL designation in the product name indicates the specific disc construction variant within the SI-Dr product family. The Coarse SL variant provides the most aggressive cut rate within the Scotch-Brite surface conditioning disc range, appropriate for surface preparation operations where maximum material removal per pass is required to minimize the number of passes needed to achieve the required surface condition. This is particularly important when working in confined areas on aircraft structure where tool access is limited.

Use the SI-Dr Coarse SL with a die grinder at the recommended operating speed. Apply moderate, consistent pressure — the coarse grade provides aggressive cutting action with moderate pressure, and excessive pressure can reduce disc life and produce an excessively rough surface that requires additional passes with finer grades to bring to the required surface condition. Follow coarse grade surface conditioning with successively finer grades (Very Fine, Ultra-Fine) as required by the surface preparation specification.

Why Choose?

Silicon Carbide Abrasive — Aggressive cutting for coarse surface conditioning
Roloc Quick-Change — Fast die grinder mounting and disc changes
Coarse Grade — Efficient heavy de-glossing and corrosion removal
Non-Gouging Construction — Non-woven conformability prevents over-cutting
3M Scotch-Brite Quality — Trusted non-woven abrasive brand

Applications

SI-Dr Coarse SL discs are used for initial surface preparation and de-glossing of aircraft surfaces, corrosion removal from structural components, heavy coating removal, and aggressive surface conditioning in tight areas and confined spaces accessed by die grinders.

Frequently Asked Questions

Q: What is 3M Scotch-Brite SI-Dr Coarse SL?
A: SI-Dr Coarse SL is a silicon carbide Roloc surface conditioning disc in Coarse grade — providing aggressive de-glossing, corrosion removal, and surface preparation with a die grinder while maintaining non-woven conformability.

Q: MPN for 3M Scotch-Brite SI-Dr Coarse SL 4-carton?

A: SI indicates silicon carbide abrasive mineral. Dr indicates the durable disc construction variant of Scotch-Brite surface conditioning discs. SL further specifies the disc construction within the product family.

Q: How many discs in a carton?
A: Each carton contains 4 Scotch-Brite SI-Dr Roloc Coarse SL Surface Conditioning Discs.

3M 55560 StiKit 236U Gold 6 x NH Grit P80C Medium Aluminum Oxide Paper Disc Roll – 100 Discs/Roll

admin — Mon, 02 Mar 2026 08:43:57 +0000

3M StiKit 236U Gold P80C 6-inch Disc Roll – 100 Discs for Aerospace Sanding Operations

3M StiKit 236U Gold P80C Medium Grit Aluminum Oxide Disc Roll provides 100 PSA (pressure-sensitive adhesive) backed coated abrasive discs on a continuous roll for high-efficiency, high-volume sanding operations. The StiKit roll format allows fast disc changes directly from the roll — peel and apply, peel and discard when worn — for rapid changeover on sanders and disc tools without individual disc packaging. The P80C medium grit grade provides effective material removal for shaping, leveling, and surface preparation operations in aerospace where moderate to aggressive sanding is required.

The gold color of the 236U identifies the aluminum oxide abrasive and the anti-loading treatment applied to the disc surface — gold (or yellow-gold) coated discs in 3M’s line typically incorporate an anti-clogging additive or coating on the abrasive surface that resists loading from sanded materials, providing extended disc life particularly when sanding materials that tend to load abrasives quickly such as aluminum (from aluminum oxide generated during sanding), body filler, and primer. Anti-loading treatment extends the effective cutting life of P80 grit discs significantly in production sanding environments.

The 100-disc roll format and 6-inch diameter are matched to the standard 6-inch PSA sanding disc tools and orbital sanders widely used in aerospace body and paint shops. The roll format provides compact storage compared to individual disc packaging and enables efficient one-handed disc changes directly from the roll dispenser.

Technical Information

3M StiKit 236U Gold uses aluminum oxide mineral on a paper backing with a PSA adhesive layer on the reverse. The C-weight paper backing provides flexibility for contoured surface sanding while maintaining sufficient stiffness for controlled material removal on flat and gently curved surfaces. The anti-loading treatment on the disc surface reduces the adhesion of sanded material to the abrasive surface, extending useful cutting life before the disc must be discarded due to loading and reduced cutting efficiency.

P80C medium grit provides effective material removal for leveling, shaping, and aggressive surface preparation — removing existing coatings, leveling body filler, removing minor surface defects, and preparing surfaces for subsequent finer grit sanding steps. In aerospace applications, P80 grit is typically used in early stages of surface preparation sequences that proceed through progressively finer grits before final surface preparation and coating application.

Apply StiKit discs directly to a compatible 6-inch PSA backing pad on an orbital or random orbital sander. The PSA backing provides firm adhesion to the backing pad during sanding while allowing clean removal when the disc is worn. Change discs promptly when cutting efficiency decreases — worn, loaded discs produce heat and reduced cut rate that reduces productivity and surface quality.

3M Scotch-Brite 29745 Maroon 6 x 1/2 Inch Medium Aluminum Oxide High Strength Disc – 40/Pack

admin — Mon, 02 Mar 2026 08:43:56 +0000

3M Scotch-Brite 29745 Maroon 6×0.5in Medium High Strength Disc – 40/Pack for Aerospace Conditioning

3M Scotch-Brite 29745 Maroon Medium Aluminum Oxide High Strength Disc is a non-woven abrasive disc designed for use with disc tools, orbital sanders, and random orbital machines for surface conditioning, paint removal preparation, and blending operations on aircraft surfaces. The 6 inch diameter by 1/2 inch thickness provides a standard disc form factor for rotary disc tool use, while the High Strength construction provides greater durability and lifespan compared to standard Scotch-Brite discs in demanding machine-applied applications.

The Maroon Medium grade designation indicates this disc provides a moderate cutting rate — more aggressive than Very Fine and Ultra-Fine grades for initial surface preparation, paint de-bonding preparation, light corrosion removal, and surface conditioning where faster material removal and de-glossing is required before subsequent finishing steps with finer grades. The aluminum oxide abrasive mineral in the disc provides consistent cutting action throughout the disc’s life as the three-dimensional non-woven construction continuously exposes fresh mineral.

The 40-pack format provides a production supply for MRO shops, aircraft maintenance facilities, and surface finishing operations that use orbital disc tools for aircraft surface preparation. The high-strength construction extends disc life compared to standard grade discs, providing better economy in high-volume surface preparation operations.

Technical Information

3M Scotch-Brite 29745 uses aluminum oxide abrasive mineral bonded in a high-density non-woven fiber web — the High Strength designation indicates a stiffer, denser web construction that resists breakdown under the higher pressures and speeds of machine-applied disc applications compared to hand pad grade non-woven constructions. The higher density and mineral loading of High Strength discs provides more aggressive material removal and faster de-glossing than equivalent hand pad grades, while maintaining the conformability and random scratch pattern benefits of non-woven abrasive construction.

Machine application with orbital or random orbital disc tools amplifies the cutting action of the Scotch-Brite 29745 compared to hand application, enabling efficient surface conditioning of larger areas in less time than manual preparation. Random orbital tool motion combined with the random scratch pattern of non-woven construction produces a particularly uniform surface preparation result with minimal directional scratch pattern that would require additional hand blending to remove.

Mount the 29745 disc on a compatible backing pad for the orbital or random orbital tool being used. Use the disc at the tool’s recommended speed range for non-woven abrasive discs — excessive tool speed can overheat the non-woven web and reduce disc life. Apply moderate, uniform tool pressure and maintain consistent tool movement to produce an even surface preparation result across the work area.

Why Choose?

High Strength Construction — Extended disc life for machine applications
Maroon Medium Grade — Effective de-glossing and surface preparation
Machine-Compatible — For orbital and random orbital disc tools

3M Scotch-Brite 18730 Green 2 x 5/8 Inch Grit 50 Ceramic Aluminum Oxide Bristle Disc – 10/Carton

admin — Mon, 02 Mar 2026 08:43:56 +0000

3M Scotch-Brite 18730 Green Grit 50 Bristle Disc – 10/Carton for Aerospace Weld and Corrosion Prep

3M Scotch-Brite 18730 Green Grit 50 Ceramic Aluminum Oxide Bristle Disc is a unique abrasive product combining the flexibility of a bristle brush with the cutting action of a coated abrasive — individual abrasive-coated plastic bristles extend from a disc hub, each bristle tip containing ceramic aluminum oxide mineral that contacts the workpiece with a flailing action as the disc rotates. This bristle disc technology provides aggressive surface preparation and corrosion removal while the individual bristle flexibility prevents gouging and over-cutting that would occur with rigid abrasive wheels or rigid flap discs.

The green color designation indicates Grit 50 coarse grade, making the 18730 appropriate for aggressive operations — weld joint preparation, corrosion removal, heavy scale removal, and initial surface preparation where significant material removal is required before subsequent finishing with finer grades. The ceramic aluminum oxide mineral provides superior cutting performance and mineral longevity compared to conventional aluminum oxide, particularly on hard and tough aerospace alloys including high-strength steels and titanium.

The 2-inch diameter disc is sized for use with die grinders and small right-angle grinders, providing access to tight areas, weld joints, inside radii, and confined spaces on aircraft structure that larger discs cannot reach. The 10-carton pack provides a working supply of discs for MRO repair operations and structural maintenance tasks.

Technical Information

3M Scotch-Brite Bristle Discs use a patented construction where individual thermoplastic bristles are coated with abrasive mineral at their working tips. The bristles are mounted in a radial pattern around the disc hub, providing an open, flexible abrasive tool that contacts the workpiece with a controlled flailing action. Each bristle tip flexes individually as the disc rotates, conforming to the surface profile and delivering abrasive mineral contact without the rigid high-pressure contact of conventional grinding wheels that can cause gouging, chatter marks, or work hardening.

Grit 50 ceramic aluminum oxide provides aggressive cutting action on tough aerospace materials — the ceramic mineral fractures at a controlled rate to expose fresh cutting edges throughout the disc’s life, providing consistent cut rate performance rather than the declining cut rate of conventional aluminum oxide that dulls without fracturing. This self-sharpening characteristic is particularly valuable for corrosion removal and weld joint preparation on hard aerospace alloys where maintaining consistent cutting action is important for efficient material removal.

Mount the 18730 on a compatible die grinder or small right-angle grinder with the appropriate arbor size. Operate at the disc’s rated maximum RPM — do not exceed the rated speed. The bristle disc is particularly effective for weld joint preparation, corrosion removal from tight areas, and accessing confined spaces on aircraft structure that larger diameter discs cannot reach.

3M 048011-04028 Scotch-Brite 7448 Gray Ultra-Fine 6 x 9 Inch Gray Hand Pad – Box of 20

admin — Mon, 02 Mar 2026 08:43:55 +0000

3M Scotch-Brite 7448 Gray Ultra-Fine Hand Pad – Box of 20 for Aerospace Finishing

3M Scotch-Brite 7448 Gray Ultra-Fine Hand Pad is a premium non-woven abrasive pad representing the finest grade within the standard Scotch-Brite hand pad line — the gray color designation identifies this pad as Ultra-Fine grade, finer than the Maroon (Very Fine) 7447, and used in aerospace and aviation applications for the final surface preparation steps, scuff sanding between topcoat coats, light surface cleaning, and producing a very fine, uniform scratch pattern for the most demanding finishing applications.

The Ultra-Fine grade of the 7448 is particularly valuable for aerospace refinishing applications where the surface must be prepared to the highest standard before final topcoat application — the very fine scratch pattern produced minimizes the leveling work required of the final topcoat and contributes to a smoother, higher-gloss final finish on aircraft exterior surfaces. The gray 7448 is also widely used for scuff sanding existing finish coats before recoating, intercoat adhesion preparation, and cleaning delicate aerospace surface materials where coarser abrasive grades would cause excessive scratch depth.

The box of 20 provides a practical production supply for aircraft paint shops, refinishing operations, and MRO facilities performing finish-quality surface preparation and intercoat scuffing on commercial and military aircraft components.

Technical Information

3M Scotch-Brite 7448 uses very fine aluminum oxide mineral bonded into a non-woven nylon fiber web at a lower mineral density than the Maroon 7447, producing the softer, finer cutting action characteristic of the Ultra-Fine grade. The lower abrasive mineral density and finer mineral particle size combine to produce a very fine scratch pattern with minimal material removal per stroke — enabling the finishing-quality surface preparation that Ultra-Fine pads are used for in aerospace finishing applications.

The Ultra-Fine grade approximately corresponds to a 400-600 grit equivalent range, making it appropriate for the finest hand-applied surface preparation operations in aerospace — scuffing between paint coats, preparing surfaces for clear coat application, removing very light contamination from sensitive surfaces, and producing a fine de-gloss on existing finish for adhesion preparation. The conformable non-woven construction of the 7448 follows the contoured surfaces of aircraft panels and components for consistent, uniform scratch pattern application without sharp edge pressure points.

For aerospace intercoat scuffing applications, use the 7448 with light, consistent pressure and uniform stroke patterns to produce an even, fine scratch pattern across the entire surface being prepared. After scuffing, remove all abrasive dust and residue with a clean tack cloth or compressed air blow-off before applying the next coat of paint or primer.
