Dewalt DW8317 Flap Disc 60 Grit Type 29 5 Inch

Product Description

The DEWALT DW8317 is a Type 29 zirconia alumina flap disc designed for aggressive material removal on metal surfaces. The conical Type 29 profile keeps the abrasive at a working angle that increases contact and stock removal rate compared to flat Type 27 discs. At 60 grit, it sits in the coarse range, making it well suited for weld blending, deburring, and surface conditioning on steel and stainless steel. The fiberglass backing plate provides rigid support while keeping disc weight low. Rated at 12,200 RPM maximum, it is compatible with standard 5-inch angle grinders fitted with a 7/8-inch arbor. Licensed electricians, fabricators, and maintenance technicians are the primary installers and operators of this disc.

This disc is intended for use on ferrous and non-ferrous metals, specifically steels and stainless steel. The 5-inch diameter and 7/8-inch arbor hole fit the most common angle grinder spindle size found in commercial fabrication shops, field maintenance, and industrial facilities. The coarse 60-grit cut rate makes it a go-to choice for initial weld seam blending and heavy scale removal before finishing passes with finer abrasives. It is sold individually.

Installation Notes

Always verify the grinder free-speed rating does not exceed the 12,200 RPM maximum marked on the disc before mounting. Ensure the grinder is unplugged or the battery is removed before changing discs. Use the correct flange and locking nut for the arbor size, and confirm the disc is seated flush before tightening. Operate with the appropriate angle grinder guard in place in accordance with ANSI B11 and applicable OSHA standards for abrasive wheel machinery.
