Diablo's Steel Demon Carbide Teeth Reciprocating Saw Blades for Thick Metal are the first carbide-tipped blades designed for extreme metal cutting; including high strength alloys, cast iron, and stainless steel. Hi-Performance Carbide teeth deliver an unmatched 100X longer cutting life metal cutting applications between 3/16” to 9/16”. An enhanced tip-to-blade connection provides extreme impact resistance, while an oversized 1" blade body provides straighter cuts with less vibration and chatter. Diablo's Perma-SHIELD non-stick coating helps the blade resist heat buildup, preventing gumming and corrosion.
