Close Coated Abrasive Flap Disc, 4-1/2 IN Dia Disc, 7/8 IN Cent

3M™ flap disc 546D provides a system for low pressure grinding, small weld removal, finishing and surface preparation with just one disc. The one step alternative to bonded wheels and fiber discs, these discs run fast enough for stock removal but provide cushioning with the flaps for a soft finish. 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.
