## Summary description

Dolfamex NAWIERTAK NWRC 3,15 is a 3.15 mm drill bit designed for precision drilling tasks. As a single-diameter cutting tool, it suits applications that require small, accurate holes. Use it for metalworking, plastics, PCB drilling, and other light industrial or hobby projects where a 3.15 mm diameter is required.

## Long description

Dolfamex NAWIERTAK NWRC 3,15 mm is a single-diameter 3.15 mm drill bit designed for precision drilling in small-diameter applications. Intended for tasks that require accurate, repeatable holes, this drill bit is suitable for metalworking, plastics, printed circuit boards (PCB), and similar light industrial or hobby uses where a compact, rigid cutting tool is required.
Advantages
The 3.15 mm Dolfamex NAWIERTAK NWRC delivers consistent hole diameter and stable performance during fine drilling operations. Its single-diameter geometry reduces wander at the drill entry, supporting improved positional accuracy. The bit is compatible with standard drill chucks and micro-drilling setups, offering straightforward mounting and replacement. Its design supports efficient chip evacuation for the materials indicated, which helps maintain cutting stability and prolongs tool life when used within recommended parameters.
Suitable for
Precision metal drilling of thin sheets and small components
Drilling in plastics and acrylics where accurate hole size is required
Printed circuit board (PCB) drilling and electronics prototyping
Hobbyist model making and light workshop tasks
Key specifications
Nominal diameter: 3.15 mm
Type: single-diameter drill bit for precision drilling
Typical materials: ferrous and non-ferrous metals (thin sheets), plastics, PCB substrates
Shank compatibility: standard cylindrical shank suitable for micro chucks and standard drill chucks
Application level: light industrial and hobbyist precision work
How to use
Secure the drill bit in a suitable chuck or collet with correct axial alignment to minimize runout. Select an appropriate spindle speed and feed rate according to the material being drilled—higher speeds for plastics and PCB substrates, moderate speeds for thin metals. Use light, steady feed pressure and pecking cycles where necessary to clear chips and avoid overheating. If drilling PCBs, consider using backing material to prevent breakout on the exit side.
Usage recommendations
For best results, use cutting fluid or a suitable lubricant when drilling metals to reduce heat and improve tool life. Inspect the bit for wear or chipping before use and replace when accuracy diminishes. Store the drill bit in a dry, protected case to preserve its cutting edge and dimensional consistency.
