Drill bits set Dedra WMT01540 — 1.5 mm x 40 mm, 10 pieces, for metal

Dedra WMT01540 is a set of 10 precision drill bits with a 1.5 mm diameter and 40 mm length, designed specifically for drilling metal. The compact set offers uniform sizing for accurate small-diameter holes in sheet metal, thin plates and light fabrication work. These drill bits are intended for tasks where precise, fine metal drilling is required and come as a convenient assortment for hobbyists, repair technicians and light industrial users.

Advantages

The set provides ten identical 1.5 mm bits for consistent hole sizing across multiple operations. With a 40 mm length, each bit reaches through thin materials while retaining rigidity for controlled drilling. Being designed for metal, the bits allow clean penetration of sheet metal and thin plates, reducing burr formation and the need for secondary finishing. The compact pack keeps the small bits organised and ready for sequential tasks.

Suitable for

• Drilling small-diameter holes in sheet metal and thin metal plates
• Hobby and model-making metalwork
• Light repair and maintenance tasks on appliances and metal housings
• Pre-drilling for small fasteners and rivets in thin metal

Key specifications

• Drill bit diameter: 1.5 mm
• Overall length: 40 mm
• Material suitability: metal
• Quantity: 10 pieces

How to use

Select a drill chuck that securely accepts a 1.5 mm shank and clamp the bit with minimal runout. Mark the drilling point on the metal surface and use a center punch if required to prevent bit wandering. Start drilling at low speed with steady, moderate pressure, and use cutting fluid or light oil when drilling thicker or harder metal to reduce heat buildup and extend bit life. Retract occasionally to clear chips and maintain cutting efficiency. After use, clean and store the bits in their pack to prevent damage and loss.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For thin sheet metal, support the workpiece to avoid bending. Replace the bit if it becomes dull or overheats; re-sharpening small bits may be impractical.
