The Tenryu HMC-20342BW heavy metal circular saw blade has a thin-kerf design coupled with a lower tooth count for effortless cutting of thick-wall mild steel (1/8 In. to 1/2 In.). Expertly crafted plates provide outstanding durability and cut-life. Ideal for hand-held metal cutting saws and dry cutters. Grind: TCG. Specially engineered alloy teeth provide exceptional cut-life and lowest cost per cut in the most demanding applications. Designed for Milwaukee metal cutting saw. The heavy metal plus series is an evolution of the heavy metal in that it features the same super thin-kerf and grinds as the heavy metal series, but features specially engineered alloy cutting tips to further extend cut-life in heavy load applications.
