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. Metal Demon's ability to drill up to 50% more holes per battery charge ensures professionals can complete more in less time. An optimized flute design removes metal debris faster, keeping the tip cooler for ultimate strength and durability in all metal drilling applications.
