## Summary description

FANAR Wiertło WDG drill bit with a 3.30 mm diameter, manufactured with four layers/variants of VHM (carbide) and a TiAlN (titanium aluminum nitride) coating. Designed for precision drilling in metalworking and machining applications, it offers wear resistance and heat protection for high-speed cutting. Suitable for use in CNC machines and precision drill presses where a small-diameter, coated carbide bit is required.

## Long description

FANAR Wiertło WDG Ø3.30 mm is a precision carbide drill bit with a 3.30 mm cutting diameter and TiAlN surface treatment. Constructed from multi-layer VHM (solid carbide), the bit is intended for demanding metalworking tasks where small-diameter accuracy, elevated cutting speeds and thermal stability are required. The TiAlN coating provides heat protection and reduced wear, making the tool suitable for high-speed machining and repeated short-run operations in CNC equipment and precision drill presses.
Advantages
The four-layer VHM construction delivers consistent hardness and cutting-edge stability throughout the tool, while the TiAlN coating increases temperature resistance and reduces friction during cutting. This combination supports prolonged tool life, maintains hole dimensional accuracy and reduces the likelihood of built-up edge when machining steels and similar alloys. The small 3.30 mm diameter enables tight tolerances and fine-detail drilling in metal components.
Suitable for
Precision drilling in steel and alloy components
CNC machining centers and small toolholders
Prototype and small-batch metal production
Drilling tasks requiring fine-diameter holes and close tolerances
Key specifications
Cutting diameter: 3.30 mm
Material: multi-layer solid carbide (VHM)
Surface coating: TiAlN (titanium aluminum nitride)
Coating purpose: improved heat resistance and wear protection
Application focus: high-speed cutting and precision drilling in metals
How to use
Mount the FANAR Wiertło WDG Ø3.30 mm in a suitable collet or precision chuck ensuring proper runout within recommended tolerances. Select cutting speeds and feed rates appropriate for carbide tooling and the workpiece material; use coolant or compressed air as required by the machined material to manage heat and clear chips. For best results, employ peck drilling or chip-break techniques when drilling deep holes and verify hole dimensions with appropriate metrology tools after machining.
Usage recommendations
Optimize spindle speed and feed to match the workpiece material and maintain steady coolant flow to maximize tool life. Replace the bit when wear affects hole accuracy or surface finish.
