For speed, long life and ease of use, nothing comes close to the power of Cubitron II abrasives.

For grinding, weld blending, deburring and other tough metal finishing jobs, 3M™ Cubitron™ II Abrasives outperform other discs in their class – thanks to a breakthrough 3M technology that re-writes the rules for speed, consistency and abrasive life. The secret lies in the revolutionary precision-shaped ceramic grain technology pioneered by 3M. As the triangular shaped grain wears, it continuously fractures to form sharp points and edges that slice through metal, and provide a fast cut, long life and smooth-running feel.

3M precision-shaped grain uses 3M microreplication technology to form sharp peaks that easily "slice" through metal - cutting cooler, faster and lasting longer than conventional grain.
Conventional ceramic abrasives grain tends to "plow" through the metal, causing heat to build up in the workpiece and the abrasive - resulting in a slower cut and shorter disc life.

3M™ Fibre Discs 782C and 787C

An unbeatable combination of performance and value

3M Fibre Discs 782C and 787C represent a new class of high-performance right angle abrasives – powered by the legendary speed and long life of 3M Precision-Shaped Grain. They are an ideal choice for applications like weld removal, beveling, edge chamfering and more – offering a faster cut and longer life than alumina zirconia (AZ) and conventional ceramic abrasives. 3M™ Fibre Disc 782C is an ideal choice for carbon steel.


3M™ Cubitron™ II Flap Discs 967A

Constructed with a poly-cotton backing that exposes fresh mineral as it wears, for a fast, forgiving cut. Performs well on many common applications, offering a great balance of fast cut and long life.

3M™ Cubitron™ II Depressed Center Grinding Wheels

Cubitron II Depressed Center Grinding Wheels are fast cutting, long lasting and require less pressure. These cool cutting wheels are ideal for heavy grinding and weld removal. Specially formulated for use on stainless and mild steel. Available with quick change attachment. DO NOT USE ON TOOLS WITHOUT GUARDS.
