3M 7010298944 Cloth Abrasive Disc 24 in 40 Grit Ao

Product Description

The 3M 7010298944 is a coated cloth abrasive disc engineered for demanding metalworking and woodworking tasks. Built on an X-weight cloth backing, this disc handles heavy sanding and grinding without breaking down. The aluminum oxide abrasive mineral is closed-coat and resin-bonded, delivering fast cutting action and consistent performance across a wide range of substrates. At 24 inches in diameter and rated to 2500 rpm, it is sized for large-surface stationary disc grinders commonly found in fabrication shops and industrial woodworking facilities. Qualified finishers and metalworkers are the primary installers and operators.

This disc is suited for metal deburring, general metalworking, and woodworking applications where a controlled, consistent cut is required. The 40-grit rating places it firmly in the aggressive stock-removal range, making it appropriate for initial surface preparation, weld cleanup, and material removal on large flat or near-flat workpieces. It is sold individually and intended for high-volume production environments where large-format abrasive discs are standard equipment.
