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.
All-in-One Metal Drilling Solution – The industry’s first three-in-one bit designed to drill mild, hardened, and stainless steel, eliminating the need for multiple bit types like Titanium, Cobalt, and Black Oxide.
Unmatched Durability and Longevity – Thermal Shield Protective Coating creates a multi-layered heat-resistant barrier, extending bit life up to 30X longer than traditional metal drill bits.
Faster, More Efficient Drilling – Cutting Edge CNC grinding process ensures precise angle tolerances, reducing bit wear and enabling drilling speeds up to 2X faster than other bits.
Precision Starts Every Time – 130° Hybrid Split Point Tip delivers quick, on-point starts in both stationary and handheld drills, preventing walking and ensuring accurate holes.
Maximized Productivity – Optimized flute design removes debris faster and keeps the tip cooler, allowing professionals to drill up to 50% more holes per battery charge, saving time and increasing efficiency.

Fantastic! Highly recommended!
Fantastic! These bits did what my Snap-on and Erwin bits could not! They drilled through a hardened stainless steel bolt with very little effort. I purchased these bits after burning up 8 bits from the two different sets, 4 from each. I will be purchasing a second set as a back up, and I will purchase them again in the future as needed. I highly recommend these bits.

Very sharp, high quality
There are few things I hate more than drilling holes. I used this new drill set this morning for the first time, and I was thrilled, but not surprised, at how well they worked. I have used a lot of different Diablo saw blades and always had good luck, so these fell right into place⦠they are fantastic.
