Benchmark Abrasives 3" zirconia quick change discs are built for aggressive grinding, weld blending, deburring, and stock removal where faster cutting on metal is the priority. The larger 3" diameter gives you more working coverage than a 2" disc, making it a strong choice for broader welds, fabricated surfaces, and general metalworking while still keeping the convenience of a compact quick change system.
Made with zirconia grain on durable X-weight cloth backing, these discs are suited for demanding dry sanding and grinding applications. Available from 24 through 120 grit, they let you move from heavy material removal into progressively finer blending without changing abrasive systems.

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.
They are best suited for aggressive metalworking applications such as weld blending, stock removal, deburring, and surface cleanup where faster cutting is more important than fine finishing.
Choose zirconia when you need more aggressive metal removal and sustained grinding performance. Aluminum oxide is generally the more economical option for lighter, general-purpose sanding.
The 3" diameter covers more surface area and is better suited for broader welds and larger work areas. A 2" disc is generally preferable when tighter access and more localized control are the priority.

No. These zirconia 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 mandrel or holder may use a 1/4" tool shank, which is a different connection.
