Dewalt DW8329 Type 29 Flap Disc 7 in 60 Grit Zirconia

Product Description

The DEWALT DW8329 is a Type 29 zirconia flap disc designed for aggressive grinding and blending on metal surfaces. Built with a 7-inch diameter and a 5/8 inches-11 threaded hub, it mounts directly to standard large-angle grinders. The 60-grit zirconia alumina abrasive delivers a consistent cut rate on steel, stainless steel, and other ferrous metals. The conical T29 profile concentrates pressure at the contact point, making it well suited for weld blending, surface preparation, and stock removal at low to moderate angles. Fabricators, ironworkers, and pipefitters reach for this disc when they need reliable material removal without frequent disc changes.

This disc is a practical choice for structural steel fabrication, pipe welding prep, and general metalworking applications in both shop and field environments. The 60-grit designation places it in the medium-coarse range, appropriate for initial weld blending or removing mill scale before finish grinding. It is sold individually and is intended for use with 7-inch angle grinders equipped with a 5/8 inches-11 spindle.

Key Features

• Type 29 conical profile for efficient material removal at low grinding angles
• Zirconia alumina abrasive grain for extended disc life on ferrous metals
• 60-grit rating suitable for weld blending and surface prep
• 7-inch diameter with 5/8 inches-11 threaded hub fits standard large-angle grinders
• Consistent cut rate reduces operator fatigue during extended use

Compatibility

Designed for use with 7-inch angle grinders equipped with a 5/8 inches-11 spindle thread. Verify maximum RPM rating of the grinder matches or exceeds the disc rating before installation.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Inspect the disc for cracks or damage before mounting and never use a damaged disc. Power down and disconnect the grinder from the power source before changing discs. Always use the appropriate guard and wear face protection rated for grinding operations in accordance with applicable ANSI and OSHA standards.
