Dewalt DW8315 Type 29 Flap Disc 5x7/8 Inch 36 Grit Zirconia

Product Description

The DEWALT DW8315 is a Type 29 zirconia flap disc designed for aggressive grinding and blending on metal surfaces. The conical T29 profile presents the abrasive at an angle to the workpiece, increasing contact area and stock removal rate compared to a flat T27 disc. At 36 grit, this disc cuts fast and is well suited for heavy material removal, weld blending, and surface preparation before coating or further finishing. The 5-inch diameter paired with a 7/8-inch arbor hole fits standard 5-inch angle grinders commonly used in fabrication, welding, and construction trades.

This disc is used in metal fabrication shops, structural steel work, pipeline work, and general maintenance where heavy grinding is required. The zirconia abrasive grain self-sharpens during use, maintaining cut rate longer than standard aluminum oxide under high-pressure applications. It is appropriate for use on carbon steel, stainless steel, and other ferrous metals. Licensed contractors, ironworkers, welders, and pipefitters will recognize this disc as a standard consumable for angle grinder work in both shop and field environments.

Compatibility

Designed for use with standard 5-inch angle grinders accepting a 7/8-inch arbor. Confirm grinder RPM rating meets or exceeds the disc's maximum RPM rating before use.

Installation Notes

This disc is installed and replaced by anyone operating an angle grinder — no licensed trade certification is required, though proper PPE including a face shield, gloves, and hearing protection is mandatory. Always ensure the grinder is unplugged or the battery pack removed before mounting or removing a disc. Inspect the disc for cracks or damage before each use and never exceed the maximum RPM marked on the disc. Follow ANSI B7.1 safe use guidelines for bonded and coated abrasives.
