Lenox METALMAX�- A new alternative to abrasive cut-off wheels.The Lenox MetalMax, 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 METALMAX� as you would a bonded abrasive wheel.FeaturesLonger 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 wheelsDiameter 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 precisionSafety - made with a solid steel body that is stronger to greatly reduce the risk of breakageLess 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 cutOne Wheel Multiple Materials - recommended for multiple types of metal including steel, sheet metal, stainless steel, rebar, cast iron, aluminum and nonferrous metals.
