Drill bit Dedra WK04075 — 4 mm diameter, 75 mm length, for metal, 1 pc

Dedra WK04075 — 4 mm diameter, 75 mm length, single-piece drill bit engineered for drilling metal. This solid twist drill is intended for use with handheld drills and drill presses to produce precise, straight holes in steel, iron and other metallic materials. The compact diameter and extended length make it suitable for reaching confined areas while maintaining accuracy for maintenance, fabrication and assembly work.

Advantages

The drill bit delivers consistent hole quality with a 4 mm cutting diameter and a 75 mm overall length that balances reach and rigidity. Its design supports accurate centring and stable cutting in metallic workpieces when used at the recommended speeds and coolant conditions. Supplied as a single piece, the bit is easy to store and replace during on-site or workshop tasks.

Suitable for

• Drilling through steel plates and structural metal components
• Creating pilot or clearance holes in iron and ferrous alloys
• Repair, maintenance and assembly tasks requiring small precision holes
• Working in tight or recessed areas where extra reach is needed

Key specifications

• Cutting diameter: 4 mm
• Overall length: 75 mm
• Intended material: metal
• Pack quantity: 1 piece
• Shank type: straight round shank (suitable for standard drill chucks)

How to use

Secure the drill bit in a compatible drill chuck and tighten firmly to prevent slippage. Mark and centre-punch the drill location on the metal surface to improve initial tracking. Select an appropriate rotational speed and apply steady feed pressure; reduce speed and use cutting fluid when drilling harder metals to extend tool life and improve hole finish. Withdraw the bit periodically to clear chips and avoid clogging during deeper holes.

Usage recommendations

Use protective equipment such as safety glasses and gloves. Match drill speed and coolant use to the metal type: higher speeds for softer metals, lower speeds and cutting fluid for hardened steels. Inspect the bit before use and replace when worn or chipped to maintain hole quality.
