Drill bit Dolfamex NAWIERTAK NWRD 2,5 — Dolfamex 2.5 mm

Dolfamex NAWIERTAK NWRD 2,5 is a 2.5 mm precision drill bit designed for small-diameter drilling tasks. Suitable for use in handheld and bench drills, this bit is intended for applications in metalworking, woodworking and plastics where accurate, narrow holes are required. The geometry and size make it appropriate for model making, delicate repair work and general precision drilling.

Advantages

The 2.5 mm diameter provides stable, repeatable hole sizes for fine work. Its construction ensures a straight drilling path and reduced wobble in compatible drill chucks. The bit's versatile design allows it to cut effectively in common workshop materials such as soft metals, wood and plastics, enabling multi-purpose use without frequent tool changes.

Suitable for

• Model making and scale building
• Electronics and PCB work requiring small holes
• Precision repair and maintenance tasks
• Woodworking details and joinery pilot holes
• Drilling in plastic components and prototypes

Key specifications

• Diameter: 2.5 mm
• Intended use: precision small-diameter drilling
• Compatible tools: handheld drills and bench drills with compatible chucks
• Suitable materials: soft metals, wood, plastics
• Typical applications: model making, repairs, general precision drilling

How to use

Secure the drill bit in the chuck of a handheld or bench drill, ensuring it is centered and tightened to prevent slipping. Select a suitable drilling speed and support the workpiece to minimize movement. For metals and harder materials, start at a moderate speed and apply steady, even pressure; for wood and plastics, a higher speed with light pressure is often effective. Use a pilot mark or center punch for exact positioning when accuracy is critical. Clear chips regularly to maintain cutting efficiency and reduce heat buildup.

Usage recommendations

Use cutting fluid or light lubrication when drilling metals to prolong tool life and improve hole quality. When working with thin or fragile materials, use backing supports to prevent tear-out on the exit side. Replace the bit if it shows signs of dulling, bending or excessive vibration to maintain hole accuracy.
