Benchmark Abrasives 2" 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. Their compact 2" size also provides the control needed for tight contours, hard-to-reach areas, and smaller work zones.
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 can be used on flat or contoured surfaces, at odd angles, and in compact spaces where larger grinding products may not fit, while the Type R quick change attachment makes it easy to move between grits as the job progresses.

Nickel
Wrought Iron
Copper
Aluminum
Fiberglass
Plastic
Hard Rubber
Wood
Stone
Common Applications
Rapid stock removal
Weld blending
Grinding
Deburring

Finishing smaller or hard-to-reach areas
The current product page specifically highlights stainless steel, aluminum, high-nickel alloys, and titanium for cool cutting during rapid stock removal, while its broader application list also includes the materials above.
Use lower grit numbers for faster, more aggressive material removal, then move to finer grits as the work shifts into blending and surface refinement.

Follow the tool manufacturer's operating and safety instructions
Frequently Asked Questions
Use a matching 2" 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 2485-20, 2486-20, and 2984-20 when fitted with a suitable 1/4" shank holder. Always confirm the tool’s accessory capacity and the RPM rating of the complete assembly.
Ceramic is positioned for more 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. The ceramic grain and grinding aid support cooler cutting during rapid stock removal on stainless steel, aluminum, high-nickel alloys, and titanium.
Yes. Their compact 2" size makes them useful on flat or contoured surfaces, odd angles, and tighter areas where larger grinding products may be harder 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, not the recommended working 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.
