Drill bits Dedra WIT01540 — 1.5 mm × 40 mm, metal, set of 3

Dedra WIT01540 — 1.5 mm × 40 mm drill bit set (3 pieces) is designed for precise small-diameter drilling in metal. These straight-shank bits fit standard drill chucks and are intended for tasks that demand accuracy, such as electronics, model making, light fabrication and metalworking where holes of 1.5 mm are required. The set contains three identical bits, allowing replacement or multiple-tool setup for repetitive jobs.

Advantages

The Dedra 1.5 mm × 40 mm bits provide consistent hole diameter and straightness thanks to their accurate machining and uniform shank size. Their 40 mm overall length gives enough reach for shallow to moderate-depth holes while remaining rigid for controlled drilling. Compatibility with standard chucks makes them easy to mount in handheld drills, drill presses or rotary tools. Supplied in a set of three, the bits offer immediate spares to reduce downtime.

Suitable for

• Precision metalworking and sheet metal drilling
• Electronics and PCB component mounting
• Model making and hobby projects involving metal parts
• Light fabrication, maintenance and repair tasks requiring small holes

Key specifications

• Diameter: 1.5 mm
• Overall length: 40 mm
• Material suitability: metal
• Shank type: straight shank for standard chucks
• Quantity: 3 pieces

How to use

Select an appropriate drill speed for metal and clamp the workpiece securely. Mount a 1.5 mm bit in the drill chuck and tighten firmly. Use cutting fluid or lubricant when drilling ferrous metals to reduce heat and prolong bit life. Begin at a low speed to establish the hole, apply steady pressure and increase speed as needed. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

Use a center punch to mark the drilling point before starting to improve accuracy and prevent bit wandering. For prolonged bit life, avoid excessive feed pressure and high speeds; match speed and lubrication to the metal type.
