Meet the Diablo Metal Demon 17/64 in. x 4.3 in. L Metal Drill Bit with a 3-Flat Shank—engineered for precision, durability, and consistent performance when you’re drilling into metal. If you’re a professional tradesperson or a serious DIYer tackling steel, aluminum, or other metals, this bit is built to keep up with your toughest jobs.
Why this bit stands out
-
3-Flat shank design: The 3-flat shank delivers superior grip and torque transfer, reducing slippage in your chuck and helping you maintain straight, true holes even under high-torque drilling.
-
Optimized geometry for metal: With a flute length of 2.7 inches and a total length of 4.3 inches, this drill bit is tuned for metal work—efficient chip evacuation and a steady cutting action that minimizes wandering.
-
Compact, precise size: 17/64 inch drilling diameter is ideal for creating clean pilot or through-holes in steel, aluminum, and other metals without overloading the bit.
-
Solid metal construction: Built to withstand the demands of metalworking, delivering dependable performance project after project.
What you can do with the Diablo Metal Demon drill bit
- Drill clean, accurate holes in cold-rolled steel, stainless steel, aluminum sheets, and other metal stock for fabrication, automotive work, or home repairs.
- Create pilot holes to guide larger cuts or taps, ensuring precise alignment and reduced bit wandering.
- Tackle metalworking tasks in tight spaces where a longer, more flexible bit would be unwieldy, thanks to its balanced length.
How it compares to standard metal drill bits
- The 3-flat shank provides a more secure grip than round shanks, translating to less slip and more consistent hole quality under high torque.
- Engineered flute and overall dimensions optimize heat management and chip clearance, reducing heat buildup and prolonging bit life during repetitive drilling.
Practical tips for best results
- Use cutting oil or plenty of lubrication when drilling metal to extend edge life and improve cut rate.
- Start with a small pilot hole if you’re working on thicker metal to guide the bit and reduce wandering.
- Operate at moderate speeds appropriate for metal drilling and apply steady, constant pressure—avoid forcing the bit.
- Let the bit do the work; stop periodically to clear chips and inspect progress to prevent overheating.
Whether you’re outfitting a workshop, upgrading your toolbox, or tackling a metal fabrication project, the Diablo Metal Demon 17/64 in. x 4.3 in. L Metal Drill Bit with a 3-Flat Shank is designed to deliver reliable, precise holes when it matters most. Add it to your drill bit assortment and experience smoother drilling and longer bit life in metal-work tasks.
