MetalMax delivers 1,000 or more cuts with no need for wheel changes. 30 times longer life than thin bonded cut-off wheels. 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. Metal Max is made with diamonds, allowing the cutting depth to stay the same throughout its life, meaning better control, reach and precision. Less odor and dust residue as the wheel does not wear down like bonded abrasives. Sparks originate only from the material being cut. Recommended for multiple types of metal including steel, sheet metal, stainless steel, rebar, cast iron, aluminum (When cutting aluminum, apply cutting wax or other type of saw lubricant to avoid chip welding) and non-ferrous metals. Designed for use on the same power tools as bonded abrasive wheels, at the same RPMs and feed forces. No changes in operating settings are required
