Dewalt DW8327 Zirconia Flap Disc 7 in 36 Grit

Product Description

The DEWALT DW8327 is a 7-inch zirconia alumina flap disc designed for aggressive material removal on metal, weld seams, and fabricated steel surfaces. Threaded for a 5/8 inches-11 arbor, it mounts directly to standard angle grinders in that size class. At 36 grit, this disc cuts fast and removes stock quickly, making it a go-to choice for grinding down welds, deburring heavy plate, and blending rough edges. The zirconia abrasive grain self-sharpens during use, maintaining a consistent cut rate longer than standard aluminum oxide flaps. Each disc is sold individually and weighs 0.72 pounds.

This flap disc is suited for metal fabrication shops, structural steel work, shipbuilding, and heavy equipment repair. It performs well on mild steel, stainless steel, and cast iron in both production grinding and field service applications. The 36-grit designation places it firmly in the coarse range, appropriate for initial stock removal rather than finishing passes. Welders, ironworkers, and pipefitters commonly reach for this disc when cleanup speed matters more than surface finish.

Key Features

• 7-inch diameter with 5/8 inches-11 threaded arbor fits standard large angle grinders
• 36 grit zirconia alumina abrasive for fast, aggressive stock removal
• Self-sharpening grain extends disc life compared to aluminum oxide alternatives
• Flap construction provides cooler cutting and reduced loading on metal surfaces
• Sold individually — unit of measure is each

Compatibility

Designed as a direct-mount flap disc for angle grinders accepting a 5/8 inches-11 threaded spindle, commonly found on 7-inch class grinders used in metal fabrication and welding applications.

Installation Notes

This disc is installed by a qualified operator or tradesperson using a compatible 7-inch angle grinder. Always power down and disconnect the grinder before mounting or removing any abrasive disc. Verify the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before operation. Inspect the disc for cracks or damage before each use and follow ANSI B7.1 safe use guidelines for bonded and coated abrasives.
