Dewalt DW8256 Type 27 Flap Disc 4.5in Z80 Grit Xp

Product Description

The DEWALT DW8256 is a Type 27 flap disc engineered for aggressive material removal and surface blending on metal. Measuring 4.5 inches in diameter with a 5/8 inches-11 threaded arbor, it mounts directly to standard angle grinders used in fabrication, welding prep, and structural steel work. The Z80 grit designation places this disc in the medium-coarse range, making it well suited for weld seam grinding, rust removal, and deburring without excessive stock removal. The XP designation indicates an extended-performance abrasive cloth construction designed to resist heat buildup and maintain cut rate through the disc life. Licensed tradespeople and fabricators in ironwork, pipefitting, and sheet metal applications rely on this disc for consistent results on ferrous metals.

This flap disc is intended for use on angle grinders in both shop and field environments. Typical applications include grinding weld beads flush, blending surface imperfections on steel plate, removing mill scale, and light stock removal on structural components. The Type 27 flat profile is the standard choice when working on flat or slightly contoured surfaces where the disc face contacts the workpiece at a low angle. It is used across residential and commercial construction, industrial fabrication shops, and maintenance and repair operations.

Installation Notes
