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. High-performance TiCo™ hi-density carbide blade delivers an unmatched up to 50X longer cutting compared to standard bi-metal blades in extreme metal cutting applications between 3/16 to 9/16 in. An oversized blade body helps produce straighter cuts with less vibration and chatter, while an enhanced carbide tip-to-blade connection provides extreme impact-resistance. Diablo's Perma-Shield® non-stick coating helps each blade resist heat and prevent gumming and corrosion.
