DT40252-QZ Extreme Metal Diamond Cutting Disc, 125 x 22.23 x 1.3 mm. Longevity of up to 1000 or more cuts without changing the disc, lasts 30 times longer than thin bonded cutting discs. The diameter of the blade is diamond-coated, so it does not decrease in size. Safety: features a stronger solid steel core to minimize the risk of breakage. Less dust residue: the Extreme diamond cutting disc operates with reduced odor and dust, as the disc does not wear down like bonded abrasives. Application examples: suitable for a variety of materials such as steel, stainless steel, cast iron, rebar, sheet metal, aluminum, and non-ferrous metals.
