Solid carbide end mill FANAR FREZ TRZPIENIOWY WEGLIK FI 4.0 Z4 HA6 VHM AT 440N X-MILL 440N

Solid carbide end mill FANAR X-MILL 440N with a 4.0 mm cutting diameter is a high-precision milling cutter designed for metalworking on CNC machines. The tool features four flutes (Z4), HA6 tolerance and VHM (solid carbide) construction with AT 440N geometry. It is intended for slotting, profiling and finishing operations where rigidity, dimensional accuracy and wear resistance are important.

Advantages

The FANAR X-MILL 440N combines solid carbide construction and a four-flute design to provide high stiffness and cutting stability at small diameters. HA6 tolerance ensures accurate concentricity and repeatable positioning in tool holders. The AT 440N geometry improves chip evacuation and surface finish when machining common steels and alloy materials. Overall, the cutter is optimized for long tool life and consistent performance in series production and precision machining.

Suitable for

• Slotting and pocketing in steel and alloy materials
• Profiling and contour milling on CNC machining centers
• Finishing passes where surface quality and dimensional accuracy matter
• High-precision components and small-diameter features

Key specifications

• Material: solid carbide (VHM)
• Cutting diameter: 4.0 mm
• Number of flutes: 4 (Z4)
• Tolerance class: HA6
• Geometry: AT 440N optimized for chip evacuation and finish
• Application: slotting, profiling, finishing

How to use

Install the end mill in an appropriate collet or holder that matches the HA6 tolerance to ensure proper runout and clamping. Use recommended spindle speeds and feed rates for the material being machined, gradually increasing to production settings while monitoring chip formation and surface finish. For slotting, maintain steady axial engagement and avoid excessive radial immersion to reduce tool deflection. For finishing passes, use reduced depth of cut and higher feed per tooth to achieve the desired surface quality.

Usage recommendations

Keep coolant or compressed air directed to the cutting zone to assist chip removal and reduce heat buildup when machining steels and alloys. Regularly inspect the cutting edges for wear and replace the tool when dimensional tolerances or surface finish degrade to maintain consistent part quality.
