The Diablo Steel Demon Carbide-tipped reciprocating blades are the first carbide-tipped blades designed for extreme metal cutting; including high strength alloys, cast iron, and stainless steel. This high performance carbide-tipped blade delivers unmatched 50 times longer cutting life than standard bi-metal blades in extreme thick metal cutting applications between 3/16” to 9/16”. High performance carbide for greater durability and cutting performance in metals with a thickness from 3/16" to 9/16" Enhanced carbide tip to blade connection for extreme impact resistance 1 in. oversized blade body for straighter cuts with less vibration Perma-SHIELD non-stick coating for less heat and friction Enhanced carbide tip to blade connection for extreme impact resistance 1 in. oversized blade body for straighter cuts with less vibration
