Dewalt DW8308 4-1/2" Zirconia Flap Disc 60 Grit Type 29

The Dewalt DW8308 is a high-performance 4-1/2" flap disc designed for aggressive material removal on metal surfaces. Featuring premium zirconia alumina abrasive grains, this Type 29 conical flap disc delivers professional-grade grinding and finishing results for metalworking applications.

Key Features:

• Zirconia alumina grit provides 3X faster material removal compared to standard fiber resin metal sanding discs
• Premium abrasive cloth construction delivers up to 15X longer life than conventional fiber resin discs
• Type 29 conical design with fiberglass backing plate for optimal grinding angles of 20-25 degrees
• 60 grit rating ideal for medium stock removal, weld blending, and surface preparation
• 7/8" arbor hole fits most standard angle grinders
• Maximum RPM rating of 13,300 for safe, high-speed operation

This flap disc combines the grinding power of a depressed center wheel with the finishing characteristics of a fiber disc, making it an excellent choice for metal fabrication, weld removal, deburring, and surface conditioning. The overlapping abrasive flaps provide consistent finish quality while the self-sharpening zirconia grains maintain cutting performance throughout the disc's life.
