DeWalt DW8309 Flap Disc, 80-Grit Zirconia, 4-1/2 In.

The DeWalt DW8309 is a 4-1/2 inch flap disc designed for use with angle grinders and other power tools requiring a 7/8 inch arbor. This zirconia abrasive disc is engineered for grinding, shaping, and material removal on metal surfaces, making it ideal for metalworking and metal preparation work.

Zirconia abrasive grit is significantly more aggressive than traditional fiber resin alternatives. The Type 29 fiberglass backing design supports optimal grinding angles between 10 and 25 degrees, providing precise control and preventing the disc from marring your workpiece. The abrasive cloth delivers consistent performance for demanding metalwork applications.
