Diablo’s Bi-Metal Reciprocating Saw Blades for Thick Metal are specifically designed for maximum performance in metal demolition applications. The blade’s ultra-hardened cutting edge delivers up to 5X longer life compared to standard bi-metal blades. Dual Tooth design features a double tooth configuration with small gullets for faster material removal and extra durability. An oversized 1″ blade body delivers straighter cuts with less vibration and chatter while Perma-SHIELD non-stick coating protects the blade from heat buildup, preventing gumming and corrosion.
