3M™ Flap Disc 947D

3M™ Flap Disc 947D 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. Effective for preparing stainless steel for #3 and #4 finishes.

3M™ Flap Disc 947D features self-fracturing ceramic aluminum oxide abrasive grain 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.3M™ Flap Discs offer an unbeatable system for grinding and blending in one easy step. The construction wears away, exposing fresh mineral to extend disc life and provide consistent cut rates. Great for weld grinding, blending, deburring, rust removal, surface prep and edge grinding on all types of metals. Flap discs can be easily adapted to most right angle grinders and typically provide a finish one grade finer than they are graded.3M™ Flap Discs offer an unbeatable system for grinding and blending in one easy step. The construction wears away, exposing fresh mineral to extend disc life and provide consistent cut rates. Great for weld grinding, blending, deburring, rust removal, surface prep and edge grinding on all types of metals. And, because their overlapping construction allows more abrasive material to be loaded onto the cutting surface, they far outlast typical discs. Flap discs are ideal for a wide range of applications, including grinding of small welds, deburring, rust removal, edge grinding, and weld seam blending.
