3M Disc Kut-Down Discs are used for a variety of collision repair jobs. They feature extremely coarse grades down to 24 grit for effective grinding and include a built-in backing plate that provides durable support and easy adapter attachment. Disc Kut-Down means that as the discs wear, the edges can be trimmed and refreshed so you can keep your discs longer and minimize wasted material.
Built-in backing plate provides durable support
Use for paint removal and metal grindingOur 3M Disc Kut-Down Discs are made with aluminum oxide, a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
Maintain stability at high temperaturesHeat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure.
