FANAR solid carbide end mill M9-44GMAX-0030 — Ø3.0 mm, R1.5, Z4, HA6, VHM, TS, B440N

The FANAR solid carbide end mill M9-44GMAX-0030 is a precision cutting tool with a 3.0 mm diameter and a 1.5 mm corner radius. Constructed from VHM (solid carbide) and finished with a TS coating, this four-flute cutter is intended for accurate slotting, profiling and finishing operations where tool rigidity and edge stability are important. The HA6 designation and B440N specification denote its geometry and application range within general-purpose and precision milling tasks.

Advantages

This solid carbide end mill provides high dimensional stability and wear resistance thanks to its VHM construction and TS surface treatment. The four-flute geometry balances material removal rate and surface finish, while the 1.5 mm corner radius reduces chipping risk at the cutter edge and improves corner strength. The small 3.0 mm diameter allows access to narrow features and fine contours in workpieces.

Suitable for

• Precision slotting and micro-milling in metals and hard materials
• Profiling and finishing operations requiring fine surface quality
• Machining narrow pockets, internal contours and tight features
• High-speed machining with small-diameter tools

When it may not be suitable

This tool may not be suitable for heavy roughing or large-volume stock removal where larger diameter cutters and fewer flutes or roughing geometries are preferred. It is also not intended for use in materials or conditions that require coolant-internal or special-chip-breaking geometries if those features are necessary for the application.

Key specifications

• Cutting diameter: 3.0 mm
• Corner radius: 1.5 mm
• Number of flutes: 4
• Material: solid carbide (VHM)
• Surface treatment: TS coating
• Geometry designation: HA6
• Application specification: B440N

How to use

Select appropriate spindle speed and feed per tooth for the workpiece material, taking into account the small 3.0 mm diameter and four-flute configuration. Use light, steady depths of cut for finishing and maintain proper tool holding to minimize runout. When slotting, ensure sufficient chip evacuation and consider climb milling for improved surface quality. Verify cutting parameters on a test cut before full production to optimize tool life and part accuracy.

What to consider before purchase

• Compatibility with your tool holder and collet system for minimal runout
• Suitability of the HA6 geometry and B440N specification for your workpiece material
• Required surface treatment and wear resistance for your production volumes
• Machine rigidity and spindle speed capabilities for small-diameter carbide tools

Usage recommendations

Use this FANAR VHM end mill for precision finishing and profiling with controlled depths of cut, ensure precise tool clamping, and adjust feeds and speeds to the material to maximize tool life and surface quality.
