Our 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. Heat-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. Vital for increasing your grinding capabilities in collision repair, our 3M™ Disc Kut-Down™ Abrasive Disc Adapter lets technicians quickly and easily adapt our aggressive 3M™ Disc Kut-Down™ Discs to a variety of common hand held shop tools – the full power of industrial abrasive discs right in the palm of your hand.
