Drill bit Dedra WM11014 — diameter 11 mm, length 142 mm, for metal, 1 pc

Dedra WM11014 drill bit with an 11 mm diameter and 142 mm overall length is designed for drilling clean holes in ferrous and non‑ferrous metals. This single‑piece metal drill bit fits standard chucks that accept an 11 mm shank and is suitable for use with both hand drills and drill presses in workshop, construction and repair environments.

Advantages

The solid design and correct geometry of the cutting edges provide reliable centring and consistent chip evacuation for metalworking. Its 142 mm length gives extended reach for deeper holes while the 11 mm diameter matches common fastening and assembly requirements. Supplied as a single piece, the bit is simple to store and replace when worn.

Suitable for

• Drilling holes in ferrous metals such as steel and cast iron
• Drilling holes in non‑ferrous metals such as aluminium, brass and copper
• Workshop and repair tasks requiring single 11 mm holes
• Use with hand drills and stationary drill presses that accept 11 mm shanks

Key specifications

• Diameter: 11 mm
• Total length: 142 mm
• Intended material: metal (ferrous and non‑ferrous)
• Quantity in pack: 1 piece
• Compatible with standard drill chucks for 11 mm shanks

How to use

Install the drill bit securely in the drill chuck, ensuring proper centring and clamping. Select an appropriate drilling speed and use cutting fluid or lubricant when working with metals to improve tool life and hole quality. Apply steady feed pressure without forcing the bit; withdraw periodically to clear chips when drilling deep holes. After use, clean the bit and store it dry to prevent corrosion.

Usage recommendations

For best results when drilling metals, use suitable cutting fluid, start with a pilot hole if precision is required, and match drill speed to the material: lower speeds for harder or thicker steels, higher speeds for softer non‑ferrous metals.
