Drill bit Dedra WIT08011 — 8 mm diameter, 117 mm length, for metal (1 pc)

Dedra WIT08011 is an 8 mm diameter drill bit with a total length of 117 mm, designed specifically for drilling metal. This single-piece bit is made for use in hand-held drills and drill presses with standard chucks, providing a straightforward solution for creating precise 8 mm holes in steel and other ferrous materials. The geometry and dimensions are intended to deliver stable drilling performance for common metalworking tasks.

Advantages

The drill bit offers a consistent 8 mm hole size and an overall length that supports deeper drilling when compared to shorter bits. Its compatibility with standard chucks makes it easy to mount in most drills. Manufactured for metalworking, the bit maintains cutting stability and alignment to reduce walking and improve hole accuracy in metal sheets, bars, and structural components.

Suitable for

• Drilling holes in steel plates and profiles
• Workshop and maintenance metalwork
• Fabrication of metal parts and assemblies
• Use with hand drills and drill presses

Key specifications

• Diameter: 8 mm
• Total length: 117 mm
• Intended material: metal (ferrous materials such as steel)
• Quantity: 1 piece

How to use

Secure the drill bit into the chuck of a hand drill or drill press and tighten according to the tool manufacturer’s instructions. Mark the drilling point on the metal surface and, if necessary, use a center punch to prevent the bit from wandering. Begin drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit type. Apply steady, moderate pressure and use cutting fluid or lubricant to reduce heat buildup and prolong bit life. Retract the bit occasionally to clear swarf when drilling deep holes.

Usage recommendations

For best results when drilling steel and other ferrous metals, use cutting oil, select appropriate drilling speeds for an 8 mm bit, and ensure the workpiece is securely clamped. Replace the bit if wear or chipping affects hole quality.
