Dewalt DWA8207H Flap Disc Type 29 60 Grit 4.5 Inches

Product Description

The DEWALT DWA8207H is a Type 29 zirconia alumina flap disc designed for aggressive grinding and blending on metal surfaces. Rated to a maximum of 13,300 RPM and sized at 4.5 inches in diameter with a 5/8-11 center hole, this disc mounts directly to standard angle grinders used in fabrication, maintenance, and industrial settings. The Type 29 angled flap configuration increases surface contact, making it well suited for material removal and edge work at a coarse 60 grit. Licensed trades and metalworking professionals rely on this disc for weld blending, rust removal, and surface prep tasks that demand consistent cut rate and durability.

This disc is appropriate for use on mild steel, stainless steel, and other ferrous metals in both shop and field environments. The coarse 60 grit rating makes it a common choice for initial weld seam grinding, deburring, and aggressive stock removal before moving to finer finishing steps. Its compact 4.5-inch format fits the angle grinders most commonly found in fabrication shops, HVAC sheet metal work, plumbing rough-in, and general mechanical contracting. The zirconia alumina abrasive provides a self-sharpening cut that extends disc life compared to standard aluminum oxide options.

Compatibility

Designed for use with 4.5-inch angle grinders equipped with a 5/8-11 spindle thread. Verify that the grinder's no-load RPM does not exceed the 13,300 RPM disc rating before installation.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder safety practices. Disconnect or power down the grinder before mounting or removing any disc, and confirm the disc is properly seated and the guard is in place before operation. Always inspect the disc for cracks or damage before each use and never operate above the rated maximum RPM. Eye protection, hearing protection, and appropriate gloves are standard PPE for grinding operations.
