Carbide End Mill FANAR FREZ TRZPIENIOWY VHM FI 3.0 Z4 HA6 for X-MILL 440N

Solid carbide end mill FANAR FREZ TRZPIENIOWY VHM FI 3.0 Z4 HA6 is a small-diameter, high-rigidity cutter designed for the X-MILL 440N series. With a 3.0 mm cutting diameter and four flutes, this tool is intended for precision milling operations such as slotting, pocketing and finishing where tight tolerances and smooth surface quality are required. The HA6 tolerance ensures consistent concentricity and reliable fit for setups demanding repeatable accuracy.

Advantages

This solid carbide end mill provides high stiffness and wear resistance typical of VHM (solid carbide) construction, improving stability during high-speed and high-precision operations. The four-flute geometry balances chip evacuation and cutting edge contact for improved surface finish on small-diameter features. The HA6 tolerance contributes to predictable tool behaviour in automated toolholders and spindle systems compatible with X-MILL 440N tooling.

Suitable for

• Precision milling and finishing of small features
• Slotting and pocketing in metalworking
• Profile machining and toolmaking applications
• High-speed machining where rigidity is critical

Key specifications

• Cutting diameter: 3.0 mm
• Number of flutes: 4 (Z4)
• Material: solid carbide (VHM)
• Tolerance class: HA6
• Compatibility: designed for use with X-MILL 440N series tooling systems

How to use

Select appropriate spindle speed and feed to match workpiece material and the small 3.0 mm diameter; reduce radial engagement and increase axial stepdowns as needed to avoid overload. Ensure the toolholder and spindle are clean and meet the HA6 tolerance requirement for correct seating. Use consistent coolant or air blast for chip evacuation when machining metals and verify runout before critical finishing passes.

Usage recommendations

For best results, use the cutter for finishing and light roughing with conservative depths of cut, prioritize stable clamping of thin workpieces, and inspect the cutting edges regularly to prevent tool breakage due to the small diameter.
