Dewalt DW8337 Type 29 Zirconia Flap Disc 24 Grit

Product Description

The DEWALT DW8337 is a Type 29 zirconia alumina flap disc designed for aggressive material removal on metal, weld seams, and fabricated steel surfaces. Measuring 4-1/2 inches in diameter with a 5/8 inches-11 threaded arbor, it mounts directly to standard angle grinders used in welding, fabrication, and mechanical trades. The 24-grit abrasive delivers fast stock removal on rough or scaled surfaces where finer finishes are not yet required. The conical Type 29 geometry angles the abrasive cloth into the workpiece, increasing surface contact and cutting efficiency compared to a flat Type 27 disc.

This disc is suited for grinding, blending, and stock removal applications in structural steel fabrication, pipe fitting, shipbuilding, and general metalworking. It is a common tool for ironworkers, pipefitters, welders, and maintenance mechanics who need rapid material removal before a finishing pass. The 4-1/2 inch diameter fits the most widely used class of handheld angle grinders in trade settings.

Key Features

• Type 29 conical profile increases workpiece contact angle for faster removal rates
• Zirconia alumina abrasive grain for durability on ferrous metals and hard alloys
• 24-grit coarseness suited for aggressive stock removal and weld grinding
• 4-1/2 inch diameter fits standard angle grinders with 5/8 inches-11 spindle thread
• Sold individually (UOM: Each)

Compatibility

Designed as a direct-mount replacement flap disc for angle grinders equipped with a 5/8 inches-11 threaded spindle, which is the standard arbor size on most 4-1/2 inch corded and cordless angle grinders.

Installation Notes

Flap discs are installed and serviced by welders, fabricators, and mechanical trades using standard angle grinders. Always confirm the grinder RPM rating meets or exceeds the disc RPM rating before mounting. Power down and disconnect or de-energize the grinder before changing discs. Inspect the disc for damage before each use and never use a disc that shows cracks, missing flaps, or delamination.
