Diablo’s Bi-Metal Reciprocating Saw Blades for Medium Metal with Full Contact Arched Design are specifically designed for maximum performance in metal cutting applications, including metal ranging from 1/16 in. to 5/16 in. The blade’s Full Contact Arched Design with ultra hardened cutting edge provides faster cuts in fewer passes, delivering up to 5X longer cutting life compared to standard bi-metal blades. An oversized 1 in. demolition body translates to straighter cuts with less vibration and chatter. Diablo’s Perma-SHIELD® coating helps protect the blade from heat, gumming and corrosion.
