Benchmark Abrasives 3" ceramic quick change discs are built for fast stock removal, grinding, deburring, and finishing where heat control matters. The ceramic abrasive cuts aggressively while a grinding aid helps reduce heat, glazing, loading, and stripping, making these discs especially useful on heat-sensitive metals such as stainless steel, aluminum, high-nickel alloys, and titanium. The 3" diameter provides greater surface coverage while remaining compact enough for contours, hard-to-reach areas, and detailed fabrication work.
The ceramic grain is resin-on-resin bonded to durable X-weight cloth for strong grain retention along with heat and moisture resistance. These discs work on flat or contoured surfaces, odd angles, and compact spaces while the Type R quick change attachment makes it easy to move between grits as the job progresses.

Materials & Applications
Common Materials
Cast Iron
Steel
Stainless Steel
Titanium
Nickel
Wrought Iron
Copper
Aluminum
Fiberglass
Plastic
Hard Rubber
Wood
Stone
Common Applications
Rapid stock removal
Weld blending
Grinding
Deburring
Edge cleanup
Surface preparation
Contour grinding
Finishing flat, angled, or hard-to-reach areas
Use lower grit numbers for faster, more aggressive material removal, then move to finer grits as the work shifts into blending and surface refinement.
Machine Compatibility
Designed for rotary quick change sanding tools using a matching 3" Type R backing pad.
Recommended Benchmark Abrasives Tools
Benchmark Abrasives Right Angle Pneumatic Quick Change Sander
Always verify that the disc, backing pad, and tool are properly matched and that the maximum operating speed of every component meets or exceeds the tool speed.
Safety Tips
Inspect the disc and holder before use
Fully secure the disc to the Type R holder before operating
Never exceed the maximum RPM of the lowest-rated component
Follow the tool manufacturer's operating and safety instructions
Frequently Asked Questions
Use a matching 3" Type R holder. Compatible choices include the Benchmark Abrasives BMT-QC90 Right Angle and BMT-QCPG Pistol Grip Quick Change Sanders. Other verified examples include Milwaukee 2984-20 with a suitable 1/4" shank holder and Dynabrade 48530, 48531, or 48532 with the matching 51346 Type R pad. Always confirm the RPM rating of the complete assembly.
Ceramic is a performance-focused abrasive for demanding grinding and sustained stock removal, particularly on difficult metals. This product also uses a grinding aid to help manage heat, glazing, and loading during use.
Yes. They are designed to cut cool during rapid stock removal and are particularly useful on materials such as stainless steel, aluminum, high-nickel alloys, and titanium.
The 3" diameter provides more working surface for faster coverage on broader areas. A 2" disc is generally preferable when maximum access and localized control are the priority.
Yes. They can be used on flat or contoured surfaces, odd angles, and compact areas where larger grinding products may be difficult to use.

No. These ceramic quick change discs are specified for dry use only.
The 25-piece mixed pack contains 5 discs each of 24, 40, 60, 80, and 120 grit.
No. 25,000 RPM is the maximum rated speed. Never exceed the RPM rating of the lowest-rated component in the disc, holder, and tool assembly.
No. The disc uses a Type R quick change attachment. A separate holder or mandrel may use a 1/4" tool shank, which is a different connection.
