Dewalt DW8252 Flap Disc 4-1/2x7/8 Inches Z80 Type 27

Product Description

The DEWALT DW8252 is a Type 27 flap disc engineered for aggressive grinding and blending on metal surfaces. Measuring 4-1/2 inches in diameter with a 7/8 inch arbor hole, this disc uses Z80 zirconia alumina abrasive grain, which self-sharpens during use to maintain a consistent cut rate. The Type 27 flat profile is suited for work on flat stock and mild angles. Fabricators, ironworkers, pipefitters, and metal finishers install this disc on standard 4-1/2 inch angle grinders for surface preparation, weld blending, and deburring tasks.

This flap disc is intended for use on ferrous metals including mild steel and stainless steel in fabrication shops, job sites, and maintenance environments. The Z80 grit designation places it in the medium-to-coarse range, making it effective for stock removal while leaving a surface finish that reduces the need for secondary operations. It is sold individually and suits both production and repair grinding applications where a controlled, consistent cut is required.

Key Features

• Z80 zirconia alumina grain self-sharpens for sustained material removal rate
• Type 27 flat profile optimized for flat and low-angle surface work
• 4-1/2 inch diameter fits standard angle grinders with 7/8 inch arbor
• Medium-to-coarse 80 grit suitable for weld blending, deburring, and surface prep
• XP construction for extended disc life compared to standard aluminum oxide flap discs

Compatibility

Designed as a direct-fit replacement flap disc for 4-1/2 inch angle grinders accepting a 7/8 inch arbor, consistent with standard Type 27 disc applications in metal fabrication and maintenance grinding.

Installation Notes

Flap discs are installed and serviced by metalworkers, fabricators, and tradespeople using standard angle grinders. Before mounting, confirm the grinder is unplugged or the battery is removed. Inspect the disc for damage before each use and never exceed the maximum RPM rating marked on the disc. Proper guard installation on the angle grinder is required per ANSI B11 and tool manufacturer guidelines.
