Drill bits Dedra WM01540 — 1.5 mm diameter, 40 mm length, set of 3, for metal

Dedra WM01540 drill bit set contains three high-precision bits with a 1.5 mm diameter and 40 mm overall length designed specifically for drilling metal. The bits are intended for use in standard drill chucks and are suitable for both hand-held drills and small machine drills. This set is aimed at fine metalworking tasks where small, accurate holes are required, such as electronics assembly, model making and precision repairs.

Advantages

The bits are manufactured to consistent dimensions to ensure repeatable hole size and fit in small components. Their length provides access to shallow and moderately recessed spots while maintaining rigidity for controlled drilling. Supplied as a set of three, the kit reduces downtime caused by breakage or wear and provides immediate spares for continued work.

Suitable for

• Drilling thin and sheet metal in electronics and PCB work
• Model making and hobby metalwork
• Precision repair tasks—jewellery, instruments and small appliances
• Pilot holes and small fastener holes in light metal assemblies

Key specifications

• Diameter: 1.5 mm
• Overall length: 40 mm
• Material compatibility: Metal (suitable for steel, aluminum, brass depending on drill speed and technique)
• Pack quantity: 3 pieces
• Shank style: standard straight shank for common drill chucks

How to use

Secure the drill bit in a compatible drill chuck, ensuring the bit is clamped straight and centred. Select an appropriate drill speed for the metal type (higher speeds for aluminium, lower speeds for hardened steel) and use cutting lubricant when drilling harder metals to reduce heat and prolong bit life. Apply steady, moderate pressure and allow the bit to cut without excessive force; withdraw periodically to clear chips when drilling deeper holes. For very small diameters, use a steady support or jig to prevent wandering.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves as needed) and match drill speed and lubrication to the metal being drilled. Replace bits at the first sign of dulling to avoid oversized holes or breakage; keep spare bits from the set available for uninterrupted work.
