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 ranging from 1/16″ to 5/16″ thick. The blade’s Full Contact Arched Design with ultra-hardened cutting edge provides faster cuts in fewer passes, resulting in less heat buildup and up to 5X longer cutting life compared to standard bi-metal blades. A dual-tooth design features a double-tooth configuration with small gullets for faster material removal and enhanced durability. An oversized blade body helps stabilize the blade for less chatter and vibration during crucial cuts. Diablo’s Perma-SHIELD non-stick coating protects each blade from heat buildup, preventing gumming and corrosion.
