Diablo's new range of Steel Demon Amped reciprocating saw blades are "AMPing Up" thick metal cutting with the introduction of the industry's first ever industrial-grade coating, black industrial cooling element (ICE). The ultra-slick black ICE provides the coolest and cleanest cutting edge and an ultra great chip evacuation. High-performance carbide delivers an unmatched up to 100x longer cutting life in metal cutting applications ranging in thickness from 3/16 to 9/16 in. The combination of Black ICE and Diablo's carbide delivers extended life and an impressive up to 2x increased performance vs standard metal cutting carbide reciprocating saw blades.Diablo made TiCo hi-density carbide delivers the greatest durability and cutting performance in thick metal applicationsBlack ICE coating protects carbide cutting edge by creating a slick, lubricant like action for a cool cutting edge and great chip evacuationEnhanced carbide tip to blade connection for extreme impact resistance1 in oversized blade body provides stability and rigidity for straighter cuts with less vibrationPerma-SHIELD resists heat build-up by protecting the blade against gumming and corrosion
