Why the 3-Flat Shank makes a difference
The 3-flat shank design delivers superior torque transfer between your drill and the bit, reducing slippage and cam-out under heavy metal-cutting loads. That means steadier starts, fewer wandering holes, and more consistent hole quality—even on stainless steel and other hard metals. The flat surfaces also provide better chuck engagement, so you can push your materials harder without losing control.
What you can drill with it
- Stainless steel and other hard metals in automotive, fabrication, and shop applications
- Thin-walled or thicker metal stock, thanks to its robust steel construction and balanced geometry
- DIY projects that require precise, repeatable holes without bit wandering
How to get the best results
- Use a lower drilling speed and steady feed—metal bits heat up quickly and require controlled cutting to maintain edge integrity
- Apply a light lubricant or cutting oil to reduce heat and extend tool life
- Begin with a center punch to guide the bit and prevent walking on hard metals
- Keep the bit cool and clear of chips to maintain accuracy and finish quality
For tasks that demand reliability and a clean, precise bore in stainless steel and other metals, the Diablo Metal Demon 31/64 in. x 6 in. drill bit with a 3-flat shank is a focused, performance-driven choice. It’s the kind of tool you reach for when the project matters and the results count.
