A new bar has been set for metal cut-off wheels with the Lenox 12" MetalMax Diamond Cut-Off Wheel, Gas Saw (1972930). Their advanced diamond technology provides extreme durability allowing 1,000 or more cuts with no need for wheel changes while maintaining speed and finish. The cutting depth remains the same throughout the life of the wheel thanks to its diamond edge coated steel body construction. Lenox's MetalMax cut-off wheels are recommended for multiple types of metal including steel, sheet metal, stainless steel, rebar, cast iron, aluminum and non-ferrous metals.
