Drill bits Dedra WK02557, Ø 2.5 mm, length 57 mm, metal, set of 2

Two-piece set of Dedra WK02557 drill bits with a 2.5 mm diameter and 57 mm overall length designed specifically for drilling metal. The set includes two straight-shank bits made to produce narrow, relatively deep holes in sheet metal, thin plates and small metal components. Construction follows the manufacturer's standard for metal drilling, providing cutting performance appropriate for small-diameter work in maintenance, electronics and precision repair tasks.

Advantages

The Dedra WK02557 drill bits offer consistent hole diameter and straightness for accurate drilling of small metal holes. Their 57 mm length allows reaching deeper points than standard short bits while maintaining rigidity suitable for controlled drilling. Supplied as a two-piece set, the bits provide a spare or an additional tool for repetitive tasks. The bits are intended for use in handheld drills and drill presses where small-diameter metal holes are required.

Suitable for

• Drilling narrow holes in sheet metal and thin metal plates
• Maintenance and repair of machinery with small fastener holes
• Electronics assembly and chassis work requiring precise, small-diameter holes
• Precision repair tasks in automotive and household metal components

Key specifications

• Diameter: 2.5 mm
• Overall length: 57 mm
• Material suitability: metal
• Quantity: 2 pieces
• Shank type: straight (compatible with standard drill chucks)

How to use

Secure the appropriate bit in the drill chuck and tighten firmly to avoid slippage. Mark the drilling point on the metal surface and, if required, use a center punch to reduce bit wandering. Start drilling at low speed to establish the hole, then increase speed as stability permits, applying steady, moderate pressure and periodic withdrawal to clear chips. Use cutting fluid or lubricant when drilling thicker or tougher metals to extend bit life and improve hole quality. After use, clean chips from the flutes and store the bits in a protective case.

Usage recommendations

For best results when drilling metal, use a pilot mark and appropriate cutting lubricant, maintain correct speed for small-diameter bits, and avoid excessive side load to preserve straightness and cutting edge life.
