-
How many pieces come per case?
Each case includes ten discs so you have everything needed to get started on your project right away.
-
How durable are these flap discs?
The overlapping abrasives wear evenly and resist loading which allows it to last much longer compared to traditional sanding discs while providing consistent finishes.
3M™ Flap Disc 769F is a high performance abrasive disc that provides a consistent cut rate. This versatile disc provides all the advantages of standard flap discs, including conformability and low gouge risk, at an affordable price.
The ceramic blend flap disc utilizes 3M Precision-Shaped Grain technology that continually fractures into sharp points. Unlike traditional alumina-zirconia mineral that plows through the substrate, Precision-Shaped Grain cleanly cuts through metal. It's ideal for use on carbon steel, stainless steel, and other heat sensitive alloys.
This long lasting, polyester backed flap disc delivers fast cutting performance. It can be used in various applications, including weld grinding, beveling, edge deburring, blending, finishing, surface preparation, scale removal, and weld spatter removal.
