Dewalt DW8302 Type 27 Zirconia Flap Disc 60 Grit

Product Description

The DEWALT DW8302 is a Type 27 zirconia alumina flap disc designed for aggressive grinding and blending on metal surfaces. Measuring 4 inches in diameter with a 5/8-inch arbor bore, this disc delivers a 60-grit cut suited for weld removal, surface preparation, and stock removal on steel and ferrous metals. At 0.17 pounds, it is a lightweight consumable that mounts directly to compatible angle grinders. The flat Type 27 profile keeps the disc parallel to the workpiece, making it the right choice for flat surface work rather than edge grinding. Fabricators, welders, and pipefitters are the primary users.

This flap disc is used in metal fabrication shops, structural steel work, and maintenance welding applications. The 60-grit zirconia construction removes material faster than aluminum oxide at the same grit rating, making it appropriate for initial weld dressing and surface conditioning before finishing passes. It is sold individually and is a standard consumable for angle grinder workflows where controlled stock removal on flat surfaces is required.

Key Features

• Type 27 flat profile for surface grinding parallel to the workpiece
• Zirconia alumina abrasive grain for fast cut rate on steel and ferrous metals
• 60 grit for aggressive stock removal and weld dressing
• 4-inch diameter with 5/8-inch arbor bore fits standard angle grinders
• Lightweight at 0.17 pounds for reduced operator fatigue during extended use

Compatibility

Designed as a standard consumable replacement for 4-inch angle grinders accepting a 5/8-inch arbor. Verify maximum RPM rating of the grinder against the disc rating before mounting.

Installation Notes

Installation and disc changes should be performed by qualified operators following ANSI B7.1 safe use guidelines for abrasive wheels. Always power down and unplug or lock out the grinder before mounting or removing the disc. Inspect the disc for cracks or damage before each use and do not mount a disc that shows any visible defects. Wear appropriate PPE including face shield, gloves, and hearing protection during operation.
