Why this drill bit stands out
-
3-Flat Shank for confident grip—the 3-flat shank minimizes slipping in the chuck, delivering consistent torque and reducing walk during start-up, especially when you’re drilling in tight spaces or working with handheld drills.
-
Stainless steel construction—built to resist corrosion and maintain edge integrity over multiple uses, so you can rely on clean, accurate holes project after project.
-
Precisely sized for clean metal holes—17/64 in diameter with a flute length of 2.7 in and an overall length of 4.3 in, providing a balanced combination of reach and control for through-holes and pocketed drilling in metal workpieces.
-
Single-piece, carded packaging—ready for quick replacement in busy workshops, with reliable, on-shelf accessibility when you need it most.
-
Diablo Metal Demon lineage—part of a line built for enduring performance in metal fabrication, automotive work, and DIY projects that demand precision and durability.
Ideal for professional fabricators, automotive hobbyists, and do-it-yourself remodelers who regularly drill into metal. The 17/64 in. size is a versatile choice for drilling pilot holes, creating precise screw clearance, or starting holes for threading in steel or aluminum components. With its corrosion-resistant stainless steel body and slip-resistant 3-flat shank, this bit helps you achieve repeatable results without re-drilling or wandering.
Practical tips to get the most from your Metal Demon drill bit: start with a light, steady feed and use a sharp bit for best results; consider a splash of cutting fluid or light lubrication when drilling into harder metals to extend edge life; and deburr the hole edges afterward to ensure clean, finished workmanship. When not in use, store in a dry place to preserve the stainless steel edge for future jobs.
