Carbide End Mill FANAR X-MILL 440N, diameter 1.5 mm, Z4, length 50 mm, HA4 coating

Solid carbide end mill FANAR X-MILL 440N with a 1.5 mm diameter and four flutes (Z4) is engineered for precision milling tasks in CNC environments. With a total length of 50 mm and a VHM (solid carbide) body, this tool is intended for small‑diameter slotting, profiling and finishing operations on metals and alloys. The HA4 surface coating increases wear resistance and helps maintain dimensional stability and cutting performance during repetitive and high‑speed machining.

Advantages

The FANAR X-MILL 440N combines a solid carbide construction with an advanced HA4 coating to provide improved hardness and thermal resistance compared with uncoated tools. The four‑flute geometry balances material removal rate and surface finish, while the 1.5 mm diameter enables access to tight features and fine detail. The 50 mm length offers reach for deeper slots and profiles without sacrificing stiffness for typical small‑tool milling applications.

Suitable for

• Precision slotting and narrow pocket machining in steel and non‑ferrous alloys
• Profiling and contouring of small features on CNC milling machines
• Finishing passes where tight tolerances and good surface finish are required
• High‑speed and repetitive machining where tool wear resistance is important

Key specifications

• Material: solid carbide (VHM)
• Coating: HA4 surface treatment for increased wear and heat resistance
• Cutting diameter: 1.5 mm
• Number of flutes: 4 (Z4)
• Total/working length: 50 mm

How to use

Select appropriate spindle speed and feed rate based on workpiece material and machine rigidity; start with conservative parameters and adjust for optimal chip formation and surface finish. Secure the tool in a high‑precision collet or holder to minimize runout. Use appropriate coolant or air blow‑off to evacuate chips and manage temperature when machining metals and alloys. For best results, perform roughing passes with lighter depth of cut and finish with reduced radial engagement and feed per tooth to achieve the required dimensional accuracy and surface quality.

Usage recommendations

Monitor tool wear and inspect the cutting edges regularly when machining abrasive alloys or hardened steels. Maintain minimal spindle runout and use balanced holders to preserve tool life and maintain consistent accuracy with the 1.5 mm diameter FANAR X-MILL 440N.
