Diablo's Metal Demon Drill Bits redefine metal drilling with the industry�s first all-in-one bit to tackle all metals: mild, hardened, and stainless steels. Diablo�s proprietary Thermal Shield Protective Coating creates a multi-layered protective barrier around the tip to shield against heat, maximizing durability and increasing the bit�s life up to 30-times longer than Titanium, Cobalt, or Black Oxide metal drill bits. A 130-degree Hybrid Split Point Tip design creates fast, on-point starts in both stationary and handheld drills
