Diablo's Steel Demon™ carbide teeth reciprocating saw blades are the first blades designed for extreme thin metal cutting in materials such as high strength alloys, cast iron and stainless steel. The blade's carbide teeth create a full barrier to heat resistance for maximum durability. These high-performance carbide blades deliver up to 50X longer cutting life than standard bi-metal blades in extreme thin metal cutting applications less than 3/16 in. thick. Each blade features TiCo™ Hi-Density carbide for greater durability and cutting performance and Perma-SHIELD® non-stick coating for less heat and friction that helps reduce gumming and corrosion.
