Why the 3-flat shank matters
The 3-flat shank design provides a secure, slip‑resistant grip in standard drill chucks, delivering improved torque transfer and reduced bit wandering. That means starting holes with precision, maintaining straight trajectories, and achieving cleaner cuts in tougher metals compared with round-shank alternatives.
Ideal use cases
- Drilling holes in steel brackets, chassis components, and metal hardware
- Fabrication work where precise hole placement is critical
- Hobbyist projects involving aluminum panels or thin sheet metal
Performance and outcomes you can expect
With a 9/64 in diameter, this drill bit is suited for small, precise holes where clean edges and controlled chip removal matter. The 1.5 in flute length helps evacuate material efficiently, reducing heat buildup and prolonging bit life during extended metal-cutting sessions.
Practical tips for best results
- Secure the workpiece with clamps to prevent movement and ensure holes start true.
- Use a steady feed and moderate RPM appropriate for the metal you’re drilling; avoid high speeds that can overheat and dull the bit.
- Apply a light cutting fluid or oil when drilling tougher metals to improve lubrication and extend bit life.
- Withdraw the bit periodically to clear chips and prevent binding.
Whether you’re outfitting a shop crate or stocking a toolbelt for on-site metalwork, the Diablo Metal Demon 9/64 in. drill bit delivers dependable performance, precise starts, and durable construction designed to handle everyday metal drilling with confidence.
