Diablo's Steel Demon Carbide Teeth Reciprocating Saw Blades are designed for thin metal cutting including EMT conduit and tubing. Hi-Performance Carbide teeth deliver an unmatched 50X longer cutting life than standard bi-metal blades. An enhanced tip-to-blade connection provides extreme impact resistance, while the oversized 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.
