Item #BC776815
3M™ Coated Flap Disc, Standard, Type 27, 4-1/2 in Dia, 7/8 in, 120, Fine, Zirconia Alumina Abrasive, X-Weight Cloth Backing, Resin Bond, Applicable Materials: Carbon Steel and Stainless Steel Applicable
- 3M™ flap disc 546D features self-fracturing alumina zirconia abrasive with a superior cut rate to aluminum oxide and versatile performance on many metal types. It is?? made with an x-weight cotton backing that supports a fast cut for light duty grinding and finishing and is?? resin coated for heat resistance. Flap discs can be easily adapted to most right angle grinders and typically provide a finish one grade?? finer than they are graded. Flap discs are three dimensional grinding discs with overlapping layers that fan out from a central hub. These abrasive coated, fiber-reinforced flaps continually wear away with use to expose fresh mineral for a fast, consistent cut. Under normal conditions, flap discs will generate a finish that is?? one grade?? finer than the finish of a fiber disc of the same grade??. The closed coat on 3M™ flap disc 546D means that the abrasive particles are tightly configured on the backing, resulting in?? maximum cut and finish consistency on metal. And, because their overlapping construction allows more abrasive material?? to be loaded onto the cutting surface, they far outlast typical discs.
