Diablo’s Demo Demon™ Carbide Teeth Reciprocating Saw Blades for Nail-Embedded Wood are the most innovative blades on the market for cutting wood with high strength fasteners. TiCo™ Hi-Density carbide-tipped blades offer up to 50X the cutting life of standard bi-metal blades. A unique plunge tip design enables faster starts and easier plunging into material. An enhanced carbide tip-to-blade connection enables extreme impact resistance while a 1 in. oversized blade body provides straighter cuts with less vibration. Diablo’s Perma-SHIELD® non-stick coating protects the blade from friction and heat buildup, preventing gumming and corrosion.
