Cover more of the workpiece with Benchmark Abrasives 3" unitized quick change discs. Fine silicon carbide and compressed, bonded non-woven nylon help produce a uniform finish on stainless steel after heavier grinding or material removal.
The larger 3" diameter covers more surface area than a 2" quick-change disc while still maintaining the control and convenience of a Type R attachment. Its open non-woven construction helps release debris and reduce loading during use, making it a strong choice for final surface refinement and preparation before polishing.

Features & Benefits
2S Fine silicon carbide for controlled fine finishing and surface refinement
Produces a fine, uniform finish, particularly on stainless steel
3" diameter provides greater surface coverage than smaller quick-change discs
Compressed unitized construction offers support while remaining conformable during finishing
Open non-woven structure helps reduce loading and release debris
Type R quick-change attachment allows fast abrasive changes with the proper holder
Useful for preparing properly refined surfaces for a subsequent polishing step
Applications
Ideal for fine finishing and surface preparation on:
Stainless steel
Steel
Cast iron
Titanium
Nickel
Wrought iron
Copper
Aluminum
Fiberglass
Plastic
Hard rubber
Wood
Stone
These 2S Fine discs are intended for surface refinement and finishing, not aggressive stock removal, heavy weld grinding, or cutting.
Finishing Performance
The 2S Fine construction is designed for light-pressure finishing where surface control and uniformity are more important than aggressive material removal. It is particularly effective on larger stainless-steel surfaces that have already been leveled or blended with a more aggressive abrasive.
Choose the 3" size for broader finishing coverage. Use it after weld leveling or deep scratch removal, then follow with polishing as needed for your desired finish.
Keep the pad matched to the 3" disc and follow the sander's mounting instructions. No separate shank-mounted holder is needed when using a suitable supplied pad.
For a quick-change tool with a 1/4" collet and approved 3" disc capacity, use the Benchmark 3" Type R Quick Change Holder (BM-QC3HLDR_1). The tool must be rated at no more than 15,000 RPM.
The 3" holder is rated higher than the disc, but that does not increase the allowable operating speed. The disc limits the complete assembly to 15,000 RPM maximum.
Inspect the disc and holder before use and replace damaged or excessively worn components.
Use only the proper 3" Type R quick-change holder.
Secure the backing pad using the tool manufacturer's mounting instructions. On collet-equipped tools, secure the separate holder's 1/4" shank in a matching collet.
Never exceed the disc's maximum rated speed of 15,000 RPM.
Confirm that every component in the disc, holder, and tool assembly is rated for the intended operating speed.
Allow the tool to reach operating speed before contacting the workpiece.
Use controlled pressure; excessive force is unnecessary for fine unitized finishing.
Follow all machine and accessory operating and safety instructions.
Frequently Asked Questions
2S Fine identifies this as a low-density, fine-grade silicon carbide unitized abrasive. It describes the construction and finishing characteristics rather than a conventional coated-abrasive grit number.
2S Fine is a finishing grade, not a numbered sandpaper grit. Choose it for controlled fine finishing and surface refinement before polishing.
Use a tool-compatible 3" Type R pad, such as the pad supplied with the Benchmark Right Angle Sander. For a 1/4" collet-equipped tool, use the separate Benchmark 3" Type R Quick Change Holder (BM-QC3HLDR_1).
No. Type R describes the disc's quick-change attachment system. The separate 3" Benchmark holder has the 1/4" shank that mounts into the tool.
The Benchmark Right Angle Pneumatic Quick Change Sander (BMT-QC90_1) is listed for 3" Type R discs at up to 15,000 RPM. Another specification-matched option is the 3M 20232 at 15,000 RPM, using the Benchmark 3" holder in its 1/4" collet. Use the correct pad and never exceed the disc's 15,000-RPM rating.
The maximum safe speed of the complete assembly is determined by its lowest-rated component. The 3" disc is rated to 15,000 RPM, so that remains the maximum even though the holder is rated higher.
Stainless-steel finishing is one of their primary applications. The fine unitized construction is designed to refine the surface and can help prepare it for a subsequent polishing step.
These are fine finishing discs rather than aggressive stock-removal abrasives. Complete heavy weld grinding and substantial material removal with a more aggressive abrasive first.
