Cut through tough metals with continuous power using the Dewalt DT40255-QZ Extreme Metal diamond cutting disc. Unlike conventional bonded abrasive wheels that shrink as they wear, this solid steel wheel maintains its full 230 mm diameter for a consistent cutting depth from start to finish. Its advanced diamond edge delivers over 1000 cuts across steel, stainless steel, cast iron, rebar, and non-ferrous metals. You also benefit from a cleaner workspace with significantly less airborne dust. Featuring a 22.23 mm bore and a 2.1 mm thickness, it is designed for reliable dry cutting on your angle grinder.
