DEWALT Extreme Metal DT40255-QZ, 230 mm, Diamond cutting disc

The DEWALT Extreme Metal DT40255-QZ 230 mm Diamond Cutting Disc is a consumable designed for metal-cutting tasks in professional fabrication and construction settings. It measures 230 mm in diameter and cuts steel, stainless steel, cast iron, rebar, sheet metal, and non-ferrous metals. The disc delivers consistent cutting performance from the first cut to the last, maintaining a steady diameter throughout its service life. A solid steel body supports the cutting edge to produce straight cuts.

The 22.23 mm bore fits compatible angle grinders, crosscut saws, and cut-off saws. This design lasts longer than conventional thin bonded cut-off wheels. In suitable applications, users can achieve over 1,000 cuts, with a service life up to 30 times that of standard abrasive alternatives. The rigid construction reduces the risk of disc breakage during operation and helps limit airborne dust. Its composition requires no special storage conditions, so the product keeps on the shelf without deterioration.
