Dewalt DW8356 Zirconia T27 Flap Disc 4.5 in 36 Grit

Product Description

The DEWALT DW8356 is a Type 27 zirconia alumina flap disc designed for aggressive stock removal and blending on metal surfaces. The disc measures 4.5 inches in diameter with a 5/8 inches-11 threaded hub and carries a 36-grit abrasive rating, making it suited for heavy grinding, weld blending, and surface prep on structural steel and fabricated components. The zirconia alumina grain self-sharpens during use, sustaining cut rate as the disc wears. Licensed trades and metal fabricators reach for this disc when a grinding wheel leaves too rough a finish but a finer abrasive would slow the work down.

This flap disc is used in metal fabrication shops, structural steel work, pipeline work, and general ironwork applications. The T27 flat-profile geometry keeps the disc flush to the workpiece, which suits flat surface blending and weld seam grinding. It is sold individually and is compatible with 4.5-inch angle grinders equipped with a 5/8 inches-11 spindle thread, the standard arbor size for small-diameter right-angle grinders used in HVAC sheet metal work, plumbing rough-in, and general trade fabrication.
