Diablo Metal Demon DMD2164JP1 Drill Bit, 21/64 in Dia, 4.6 in OAL, Three-Flat Shank

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 30X 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 2X than other bits. A 130 deg 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. The three-flat shank design prevents slippage for accurate hole drilling. 3-in-1 bit solution creates fast clean holes in all metal applications, eliminating the need to carry multiple bit types Up to 30X longer life than standard titanium, cobalt and black oxide drill bits, resulting in a savings up to 230 dollar per bit Thermal Shield Protective Coating™ protects the tip against heat, increasing bit life and maximizing bit durability Cutting Edge™ automated precision CNC grinding process allows the bits to slice through all metal types up to 2X faster holes than other bits Split point tip (130 deg) makes pre-drilling obsolete and maintains the tip's sharpness resulting in increased speed, accurate starts and precise holes Engineered with productivity top of mind, professionals can drill up to 50% more holes per battery charge allowing more work to be completed in less time and for less cost Optimized flute design removes metal debris and shavings faster, keeping the tip cooler for ultimate strength and durability Ideal for metal (mild steel), cast iron, stainless steel and sheet metals Can also be used to drill through wood and plastic
