Diablo's Metal Demon Drill Bits redefine metal drilling with the industry's first three-in-one bit to tackle all metals - mild, hardened, and stainless steels. Long-gone are the days where professionals must purchase and carry multiple bit types (Titanium, Cobalt, and Black Oxide), the Metal Demon bit's exclusive design brings a one-bit solution for any application ensuring maximum durability, speed, precision, and productivity. 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. Cutting Edge, an automated precision CNC grinding process, ensures strict industrial standard angle tolerances that create a cutting motion to minimize bit wear allowing for faster hole drilling up to 2-times than other bits. A 130-degree Hybrid Split Point Tip design creates fast, on-point starts in both stationary and handheld drills. Productivity is now a concern of the past. An optimized flute design removes metal debris faster, keeping the tip cooler for ultimate strength and durability in all metal drilling applications.
