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 angle tubing and metal ranging between 1/16″ and 5/16″ in thickness. The blade’s oversized design with an ultra-hardened cutting edge provides faster and more rigid cuts in fewer passes. Diablo’s Perma-SHIELD® non-stick coating protects the blade from heat buildup. All combined benefits provide up to 5X longer blade life compared to standard bi-metal blades
