Aggressive Yet PreciseFor auto body jobs requiring a coarse grit abrasive, our 3M™ Stripping Discs provide an aggressive cut that translates to a consistent finishthat makes subsequent auto body stages easier and less time consuming. Durable aluminum oxide mineral abrasive self-fractures during use, continually exposing fresh cutting surfaces to keep the disc sharper longer. Non-woven fibers act like tiny springs, providing superior conformity and helping preserve irregular or contoured surfaces. This combination also resists loading and reduces heat for longer disc life. And the small 2" size makes the Stripping Disc ideal for specialty jobs requiring more precision, such as finishing disc brakes, polishing bare metal and removing used gaskets from engine parts.About Aluminum Oxide AbrasiveAluminum oxide mineral is popular among industrial and auto body professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose freshcutting edges in use, whereas traditional abrasives quickly wear down. Due to its fast cut-rate, hardness, strength, and low heat retention, it is widely used in grinding applications as well as in sanding and finishing. Aluminum oxide is suitable for a wide variety of materials in metalworking, including ferrous alloys.
