When your metalwork demands dependable performance, the Diablo Metal Demon 1/2 in. x 6 in. Stainless Steel Drill Bit with a 3-Flat Shank is built to deliver. Crafted in stainless steel for durability and corrosion resistance, this bit is purposefully designed to tackle thick metals with precision and control.
Key features that set this bit apart include a 1/2" drill size paired with a 6" overall length and a 4" flute length. The extended flute helps evacuate chips efficiently, enabling cleaner holes in deeper workpieces and reducing heat buildup that can dull cutting edges. The 3-Flat Shank enhances torque transfer, delivering steady, slip-free performance under heavy drilling loads—so you can push harder without losing control.

3-Flat Shank for superior torque transfer — minimized slippage in power drills, even during high-torque drilling.
-
Stainless steel construction — excellent corrosion resistance and long–life durability in metalworking environments.
-
6" overall length with 4" flute — reach tight spaces and drill deeper holes with cleaner chip evacuation.
-
1/2" drill size — ideal for through-holes and sizable pilot holes in steel, iron, aluminum, and other metals.
-
Carded packaging — ready to integrate into professional tool kits, with a single drill bit per package for easy stocking.
Who is this for? It’s an excellent choice for machinists, automotive technicians, metal fabricators, and DIY enthusiasts who need reliable performance on metal projects—from fabricating brackets and chassis components to enlarging holes in structural steel. If you routinely work with metals and require a bit that holds its edge while delivering accurate hole diameters, this Diablo Metal Demon bit is a strong companion.
How it excels versus common alternatives Unlike standard round-shank bits that can slip under load, the 3-flat shank of this Diablo drill bit locks into the chuck for consistent torque transfer and reduced wandering. Its stainless steel construction fights heat and corrosion, helping maintain a sharp cutting edge longer than cheaper alloys. The combination of a robust 1/2" diameter and a 6" length makes it a versatile choice for both through-holes and deeper bore applications in metalworking tasks.
Tips for best results:
- Lubricate with a light cutting oil to reduce heat and extend life when drilling through steel or other metals.
- Secure your workpiece with clamps to prevent movement and ensure clean, accurate holes.
- Use a controlled pecking approach to clear chips and avoid overheating—especially in thicker materials.
- Begin at a lower speed and increase gradually as you establish a clean cut, monitoring for dulling or chatter.
