Lenox MetalMax 1972921 Cut-Off Wheel, 4-1/2 in Dia, 3/64 in Thick, 7/8 in Arbor, 40, 50 Grit, Diamond Abrasive

Lenox MetalMax Diamond Edge cut-off Wheel 4-1/2 x 7/8 in, is an alternative to bonded abrasive cut-off wheels. Breakthrough diamond technology delivers 1,000 or more cuts and 30X longer life than thin bonded cut-off wheels without sacrificing speed or finish. Made of solid steel to greatly reduce the risk of breakage, the combination of a steel body with a diamond edge allows MetalMax to hold its original wheel diameter until the last cut, meaning better control, reach and cut precision throughout the wheel life. The enhanced design substantially reduces dust particles and lessens odor. Lenox MetalMax is suitable for metal cutting applications including steel, sheet metal, stainless steel, rebar, cast iron, aluminum and non-ferrous metals and works at the same speeds and feeds as thin bonded abrasive wheels. Average performance in 1 in carbon steel square tube vs. thin bonded abrasive cut-off wheels cutting wax or saw lubricant is recommended to avoid chip welding when cutting aluminum. Lenox Metalmaxâ„¢ is designed for use in the same power tools as bonded abrasive wheels, at the same rpms and feed forces Lenox Metalmaxâ„¢ is recommended for multiple-types of metal including steel, sheet metal, stainless steel, rebar, cast iron, aluminum and non-ferrous metals Average performance for 4-1/2 in wheel in one carbon steel square tube vs thin bonded abrasive cut-off wheels When cutting aluminum, it is recommended to apply cutting wax or other type of saw lubricant to avoid chip welding Metalmaxâ„¢ delivers 1000 or more cuts with no need for wheel changes, that is 30 times longer life than thin bonded cut-off wheels Long-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 Because Lenox Metalmaxâ„¢ is made with diamonds, it doesn't get smaller, the cutting depth stays the same throughout its life, meaning better control, reach and precision
