Drill bit Dolfamex NAWIERTAK NWRD 1.6 mm

Dolfamex NAWIERTAK NWRD 1.6 mm is a precision drill bit engineered for fine-detail drilling. With a 1.6 mm cutting diameter, this slim drill bit is suitable for making small, accurate holes in materials compatible with high-speed rotary tools and standard drill chucks. The bit is intended for tasks that require tight tolerances and minimal material removal, commonly used in electronics, model making and delicate repair work.

Advantages

The Dolfamex 1.6 mm drill bit offers consistent hole quality and a narrow profile that reduces the risk of material splitting. Its design supports precise centering and clean chip evacuation for materials appropriate to small-diameter drills. The bit's compatibility with standard chucks makes it easy to install and use with commonly available handheld and bench drills.

Suitable for

• Drilling printed circuit boards and electronic components
• Model making and scale hobby work
• Instrument and watch repair requiring small holes
• Fine mechanical assemblies and prototyping

Key specifications

• Cutting diameter: 1.6 mm
• Intended use: precision/small-diameter drilling
• Compatible holders: standard drill chucks and rotary tool collets that accept 1.6 mm shanks
• Typical applications: electronics, modelling, instrument repair

How to use

Secure the Dolfamex 1.6 mm drill bit in a suitable chuck or collet, ensuring it is seated and tightened to avoid runout. Select an appropriate rotational speed for the material being drilled—higher speeds for soft plastics and lower speeds for harder materials—and apply gentle, steady pressure. Use cutting fluid or compressed air if recommended for the material to improve chip removal and reduce heat. After drilling, withdraw the bit while it is still rotating slowly to clear chips and prevent jamming.

Usage recommendations

For best results, start with a center punch or pilot marking when drilling brittle or very thin materials, and test drill on a scrap piece to confirm speed and feed settings. Replace the bit if signs of wear or dulling appear to maintain hole accuracy and avoid damage to sensitive components.
