Dewalt DW8270 Flap Disc 7in X 5/8in-11 Z40 T27 Xp

Product Description

The DEWALT DW8270 is a Type 27 (T27) flap disc designed for aggressive material removal on metal surfaces. It features a Z40-grit zirconia alumina abrasive, which delivers consistent cut rate and long service life under heavy grinding loads. At 7 inches in diameter with a 5/8 inches-11 threaded hub, this disc mounts directly to standard large-angle grinders. The flat T27 profile keeps the disc surface parallel to the workpiece, making it well suited for grinding flush to a surface or blending welds on flat stock. Fabricators, ironworkers, and metal tradespeople reach for this disc when they need material removed fast without repeated disc changes.

The DW8270 is intended for use on ferrous metals including structural steel, plate, pipe, and fabricated assemblies. The T27 geometry and Z40 grit make it a practical choice for weld blending, surface conditioning, and stock removal in both shop and field environments. It performs on flat or near-flat workpieces where a depressed-center profile would limit access. This disc is sold individually (UOM: Each) with a minimum order quantity of 5 units, making it appropriate for shop stocking or multi-tech supply orders.
