DEWALT, DT40252-QZ, 125 mm Diamond cutting disc

The DEWALT Extreme Metal Diamond Cutting Disc is a diamond cutting disc designed for cutting a wide range of metal materials. It handles steel, stainless steel, cast iron, rebar, sheet metal, aluminium, non-ferrous metals, and alloy steels. The disc is intended for professional metalworking, fabrication, installation, and maintenance applications where intensive cutting performance is required. This positions it for use in fabrication shops, on construction sites, and in maintenance settings. The product is supplied as a single unit per pack.

The diamond cutting edge is engineered to deliver more than 1,000 cuts and to last up to 30 times longer than traditional bonded cut-off wheels. A solid steel body helps reduce the risk of disc breakage during operation. The diamond edge maintains the disc's original diameter throughout its service life for consistent cutting depth. At 100 g, the disc is lightweight for its class, reducing load on the grinder during extended cutting sessions. These characteristics make it suited to repeated use in demanding workshop and on-site environments.
