Benchmark Abrasives 2" zirconia quick change discs are built for aggressive grinding, weld blending, deburring, and stock removal where faster cutting on metal is the priority. The compact 2" diameter gives you strong control in smaller work areas, around contours, and in tighter spaces while the X-weight cloth backing provides the support needed for demanding handheld applications.
Compared with general-purpose aluminum oxide, zirconia is the better choice when heavier material removal and sustained metal grinding are more important than fine cosmetic finishing. Available from 24 through 120 grit, these discs give fabricators and maintenance professionals a practical range for coarse grinding, blending, and surface preparation.

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.
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 choice for lighter, general-purpose sanding.
Use a matching 2" Type R quick change backing pad. The backing pad is sold separately.
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.
