The Benchmark Abrasives 3" quick change stripper discs are the standard, general-purpose option for removing paint, rust, coatings, adhesives, epoxy, oxidation, and other surface contamination. Silicon carbide abrasive is distributed throughout an open nonwoven nylon web, delivering effective stripping action without the heavy stock removal of a conventional grinding abrasive.
The larger 3" diameter provides more surface coverage than a 2" quick-change disc while still offering excellent control for localized surface preparation, contours, and smaller work areas. The Type R quick-change attachment allows fast disc changes, while the open-web construction helps shed debris and resist loading during fabrication, automotive, restoration, maintenance, and general metalworking applications.

Features & Benefits
Standard general-purpose stripping disc for everyday surface preparation.
Open nonwoven construction helps resist loading and shed debris.
3" diameter provides increased coverage compared with smaller quick-change discs.
Type R attachment allows fast disc changes between operations.
Flexible web conforms well to contours and irregular surfaces.
Designed for coating and surface-contamination removal rather than heavy stock removal.
Materials & Applications
Ideal for removing:
Paint
Rust and oxidation
Coatings
Adhesives
Epoxy
Light scale and surface contamination
Suitable for use on:
Steel
Stainless steel
Cast iron
Aluminum
Copper
Brass
The 3" diameter is well suited for localized stripping where more surface coverage is desired while retaining the control and convenience of a quick-change system.
Machine Compatibility
Requires a Benchmark Abrasives 3" Type R Quick Change Holder, sold separately.
Use with a compatible die grinder or pneumatic grinder that accepts the holder's 1/4" shank, is approved for a 3" accessory, and has a maximum no-load speed at or below the disc's 10,500 RPM rating.
Choose a low-speed tool for these 3" discs. The Benchmark BMT-QC90_1 runs at 15,000 RPM, above this disc's 10,500 RPM limit, so it is not a match.
Safety Tips
Never exceed the maximum rated speed of 10,500 RPM.
Always use the correctly sized 3" Type R quick-change holder.
Confirm the disc is fully engaged with the holder before starting the tool.
Verify the tool is approved for a 3" accessory and does not exceed 10,500 RPM.
Inspect the disc and holder before use and replace damaged components.
Allow the abrasive to perform the stripping action rather than applying excessive pressure.
Test on an inconspicuous area when preserving the underlying finish is important.
Follow all machine, holder, and abrasive safety instructions.
Frequently Asked Questions
The Black version is the standard general-purpose option for everyday removal of paint, rust, oxidation, coatings, adhesives, epoxy, and other surface contamination.
They require the Benchmark Abrasives 3" Type R Quick Change Holder, which is sold separately.
No. The disc attaches to the matching Type R holder, and the holder's 1/4" shank mounts into the compatible tool.
The 3" diameter covers more surface area per pass, making it useful when you want greater coverage while retaining the control and fast-change convenience of a compact Type R system.
Black is the all-around choice for everyday stripping. Blue uses harder resins for longer life with a slower, more controlled cut, while Purple uses sharper grains for faster, more aggressive removal.
It uses silicon carbide abrasive distributed throughout an open nonwoven nylon web.
They are designed for controlled surface stripping rather than heavy stock removal. Because they are still abrasive products, test first when preserving dimensions or a finished surface is critical.
Use a tool approved for 3" discs with a matching Type R holder and a maximum no-load speed of 10,500 RPM or less. The Dynabrade 49425 (3,200 RPM, 1/4" collet) meets the speed and shank requirements, but its 3" disc-and-holder capacity must be confirmed before use.
