## Long description

Dolfamex NAWIERTAK NWRC 3,15 WZM — ø3.15 mm precision metal/wood drilling is a twist-style drill bit designed for small-diameter, accurate holemaking in both metal and wood. The 3.15 mm cutting diameter and the bit's specialized geometry provide stable cutting action and consistent hole size, suitable for delicate fabrication tasks, electronics work, and fine woodworking. The bit fits standard chucks on hand drills and drill presses and is intended for tasks that require repeatable precision rather than high-volume drilling.
Advantages
The drill bit offers a precise 3.15 mm diameter with geometry optimized for stable chip evacuation and reduced wandering on start. Its design delivers consistent hole diameter across a range of materials including soft and hard woods and many metals. Compatibility with common hand drills and drill presses makes it practical for workshop and bench use. The construction and cutting profile focus on dimensional accuracy and controlled cutting rather than heavy-material removal.
Suitable for
Precision metal drilling in thin sheets and small parts
Fine woodworking and cabinetry detail holes
Electronics and PCB prototyping where small, accurate holes are required
Hobbyist model making and instrument repair
Key specifications
Cutting diameter: 3.15 mm
Intended materials: metals and wood
Geometry: specialized twist profile for stable cutting and consistent hole dimensions
Compatibility: standard drill chucks on hand drills and drill presses
Typical use: precision, low-to-moderate feed drilling
How to use
Secure the workpiece and select an appropriate drill speed for the material: slower speeds for harder metals, moderate speeds for softer metals and wood. Fit the 3.15 mm bit in the drill chuck and tighten firmly. Start drilling with light axial pressure to establish the hole and avoid walking; use a center punch on metal sheets if extra accuracy is needed. Apply steady feed and withdraw occasionally to clear chips when drilling deeper holes. For metal, use cutting fluid as required to reduce heat and prolong bit life.
Usage recommendations
For best results use the bit for precision, low-force drilling operations; avoid excessive speed and feed that can cause overheating or premature wear. When drilling thin metal sheets, support the workpiece to prevent deformation and use a backing piece to improve hole quality.
