Solid carbide end mill FANAR FREZ TRZPIENIOWY VHM Ø3.0 mm Z4 HA6 for MASTER MILL 440N

Solid carbide end mill FANAR FREZ TRZPIENIOWY VHM Ø3.0 mm Z4 HA6 for MASTER MILL 440N is a precision milling cutter with a 3.0 mm diameter and four flutes. Manufactured from solid carbide (VHM) and specified to HA6 tolerance, the tool is intended for high-rigidity machining of small features. It is suitable for slotting, pocketing and finishing operations on hardened and non-ferrous materials when compact tool geometry and dimensional accuracy are required.

Advantages

The solid carbide construction delivers high stiffness and wear resistance, supporting stable cutting at small diameters. Four flutes provide a balance between chip evacuation and surface finish, while the HA6 tolerance ensures consistent dimensional accuracy for repeatable machining. The geometry is optimized for use in compact setups such as the MASTER MILL 440N, enabling precise small-feature milling with reduced deflection.

Suitable for

• Precision slotting in hardened and non-ferrous materials
• Pocket milling of small cavities and features
• Finishing passes to achieve tight dimensional tolerances
• High-rigidity setups and compact machining centers

Key specifications

• Material: solid carbide (VHM)
• Diameter: 3.0 mm
• Number of flutes: 4 (Z4)
• Tolerance class: HA6
• Typical applications: slotting, pocketing, finishing

How to use

Mount the end mill in a suitable collet or tool holder compatible with the MASTER MILL 440N and ensure correct clamping to the specified tolerance. Select cutting parameters according to the workpiece material, flute count and the small diameter: use conservative feed and speed values when machining hardened materials and increase feed within recommended limits for non-ferrous alloys. Maintain appropriate coolant or air blast to aid chip evacuation and reduce heat buildup. Inspect tool runout before machining to minimize deflection and ensure dimensional accuracy.

Usage recommendations

Use low radial engagement and moderate axial depth of cut for best stiffness and surface finish. Rebalance feeds and speeds when switching between hardened and non-ferrous materials, and replace the cutter at the first sign of wear to preserve tolerance and part quality.
