Drill bit Dedra WK04275 — 4.2 mm diameter, 75 mm length, for metal (1 pc)

Dedra WK04275 is a single 4.2 mm diameter drill bit with a 75 mm overall length designed specifically for drilling metal. Manufactured as a one-piece cutting tool, this bit fits hand drills and drill presses and is intended to create accurate small-diameter holes in steel and other ferrous materials. The product is supplied as a single unit and is suitable for tasks in metal fabrication, maintenance, repair and workshop use where a compact metal drill bit is required.

Advantages

The single-piece construction provides rigidity and consistent concentricity for precise hole making in metal. Its 4.2 mm cutting diameter and 75 mm length allow access to confined spaces while maintaining sufficient working length for standard metalworking tasks. Compatibility with both hand-held drills and drill presses makes it versatile for on-site repairs and workshop operations. Being optimized for metal, the bit resists deformation under typical drilling loads encountered in steel and similar ferrous materials.

Suitable for

• Drilling holes in steel sheets and metal plates
• Maintenance and repair tasks on machinery and equipment
• Metal fabrication and assembly work requiring small-diameter holes
• Workshop and hobby projects using hand drills or drill presses

Key specifications

• Diameter: 4.2 mm
• Overall length: 75 mm
• Material application: Metal (ferrous materials)
• Pack quantity: 1 piece
• Tool type: One-piece twist drill bit suitable for hand drills and drill presses

How to use

Secure the workpiece to prevent movement and select an appropriate drilling speed for metal, typically lower speeds for harder steels. Mark the drilling point and, if necessary, use a center punch to guide the bit. Fit the Dedra WK04275 drill bit into the chuck of a hand drill or drill press and tighten securely. Apply steady, moderate pressure and allow the bit to cut; withdraw occasionally to clear chips and reduce heat buildup. Use cutting fluid or lubricant when drilling thicker or harder metal to extend bit life and improve hole quality.

Usage recommendations

For best results, use appropriate personal protective equipment, clamp the workpiece, and apply cutting fluid when working with harder ferrous metals. Match drilling speed to the material hardness and avoid excessive side loads to maintain bit life and hole accuracy.
