FANAR solid carbide milling cutter (end mill) Ø8.0 mm, 19/63 mm length, Z4, HB8 coating, VHM, X-MILL 440N

FANAR solid carbide milling cutter X-MILL 440N with an 8.0 mm cutting diameter and four flutes is designed for precision metalworking tasks in CNC machining. The tool is manufactured from solid carbide (VHM) to provide high rigidity and dimensional stability. A specialized HB8 wear-resistant coating improves surface finish and tool life under typical industrial cutting conditions. The length specification 19/63 mm denotes the cutting length and overall length suitable for a range of slotting and profiling operations where access and reach must be balanced with stiffness.

Advantages

The end mill combines the hardness and heat resistance of solid carbide with a multi-layer HB8 coating to reduce flank wear and extend tool life. Four flutes provide a balance between chip evacuation and surface finish, making the cutter suitable for finishing passes and semi-finish machining. The tool geometry and coating are optimized for consistent cutting performance, dimensional accuracy and reduced need for frequent tool changes in repetitive CNC cycles.

Suitable for

• Slotting and pocketing in steel and alloy materials
• Profiling and contour milling in production parts
• Finishing passes to achieve tight dimensional tolerances
• High-volume CNC machining with stable setups

Key specifications

• Cutting diameter: 8.0 mm
• Number of flutes: 4 (Z4)
• Material: solid carbide (VHM)
• Coating: HB8 wear-resistant coating
• Cutting length / overall length: 19/63 mm

How to use

Select spindle speeds and feed rates appropriate to the workpiece material and machine rigidity; use established milling parameter charts for solid carbide tools as a starting point and adjust for coating and cutter diameter. Use appropriate coolant or lubrication according to material recommendations to control temperatures and improve chip evacuation. Ensure the tool is mounted securely in a suitable holder and check runout to maintain surface finish and dimensional accuracy.

Usage recommendations

For best results, use this end mill in stable setups with minimal overhang and maintain recommended cutting parameters for solid carbide tools. Replace the cutter when wear affects tolerances or surface finish to avoid part rework. For abrasive or hard materials, reduce cutting speed and increase coolant flow to extend tool life.
