Introducing the Dewalt Extreme Metal Diamond edge blade using the same technology used with the Lenox METALMAX� wheel who are also part of the SBD Dewalt Group The Extreme Diamond Edge is the new alternative to abrasive cut off wheels, delivers more than 1000 cuts with no need for wheel changes. That is 30 times longer life than thin bonded cut off wheels. Recommended for multiple types of metal including steel, sheet metal, stainless steel, rebar, cast iron, aluminum and non-ferrous metals. When cutting aluminum, it is recommended to apply cutting wax or other type of saw lubricant to avoid chip welding. Designed for use in the same power tools as bonded abrasive wheels, at the same RPMs and feed forces. No changes in operating settings are required. Use this EXTREME Metal blade as you would a bonded abrasive wheel. Features Longer Life - Advanced diamond technology provides extreme durability in metal cutting applications, leading to increased productivity, reduced downtime, and a lower cost per cut compared to thin bonded cut-off wheels Diameter Retention - The blade is made with diamonds, so it doesn't get smaller. The cutting depth stays the same throughout its life, meaning better control, reach and precision Safety - made with a solid steel body that is stronger to greatly reduce the risk of breakage Less Dust Residue - generates less odor and dust residue as the wheel does not wear down like bonded abrasives. Visible sparks originate only from the material being cut One Wheel Multiple Materials - recommended for multiple types of metal including steel, sheet metal, stainless steel, rebar, cast iron, aluminum and nonferrous metals 2 Blades Included in this pack
