3M 87149, Cubitron II File Belt Kit, 87149, 1/2 x 18 in, 7010327546, 25 per case

3M Precision-Shaped Grains
The 3M Cubitron II File Belt Kit allows you to try a range of abrasive file belts in one convenient package. This pack features belts that feature precision-shaped ceramic grain which continually fracture into super-sharp points and edges that slice cleanly through metal, rather than gouging or plowing as traditional abrasives do. This creates a super-fast cut and lessens heat build-up in the workpiece, reducing heat-related stress cracks and discoloration. Moreover, because the abrasives themselves stay cooler and sharper, they last significantly longer than conventional ceramic grain belts, decreasing costs and reducing belt changeovers.

Durable Design
The exceptionally fast cut and long life of precision-shaped grain make this belt ideal for industrial environments. It is also heat resistant, produces a uniform finish over the life of the product, and helps eliminate burning during end-grain sanding applications. The tough cloth backing on the 984F and 947A belts provide durability and the mineral is resin bonded to the backings for reliable performance, even under high heat and pressure.
