FANAR solid carbide end mill M9-44GMAX-0080 Ø8.0 mm R4.0 Z4 HA8 VHM TS B440N MasterMill

FANAR solid carbide end mill M9-44GMAX-0080 Ø8.0 mm R4.0 Z4 HA8 VHM TS B440N MasterMill is a full-carbide, four‑flute cutter with an 8.0 mm nominal diameter and a 4.0 mm corner radius. The tool is produced for precision finishing and semi‑finishing operations in metallic materials where dimensional stability and wear resistance matter. The HA8 geometry/coating and VHM construction provide a balance of edge life and surface quality suitable for demanding machining cycles under MasterMill B440N guidelines.

Advantages

The solid carbide construction ensures high rigidity and thermal stability for consistent performance in continuous and interrupted cuts. The HA8 geometry/coating improves wear resistance and helps maintain cutting edge integrity, reducing frequency of tool changes. Four flutes deliver efficient chip evacuation and a favorable feed-per-tooth range for finishing passes, while the 4.0 mm corner radius reduces chipping at corners and supports smoother transitions on contoured surfaces.

Suitable for

• Finishing and semi‑finishing of steel alloys and other metals
• High‑precision contour milling and pocketing
• Operations requiring improved tool life and surface finish
• Short to medium length machining cycles with stable setups

Key specifications

• Diameter: 8.0 mm
• Corner radius: 4.0 mm
• Number of flutes: 4
• Material: solid carbide (VHM)
• Coating/geometry: HA8
• Application type: finishing and semi‑finishing

How to use

Select appropriate spindle speed and feed based on workpiece material and machine rigidity, using the tool's four‑flute geometry to set a suitable feed per tooth for finishing cuts. Use coolant or appropriate cutting fluid where recommended for the work material to manage heat and chip removal. For best results, program gradual step‑downs to reach final depth of cut and avoid excessive entry angles; use the 4.0 mm corner radius to maintain surface integrity on radius transitions.

Usage recommendations

The tool is intended for use on rigid machine setups with stable toolholding. For hardened or abrasive materials, monitor tool wear and adapt feeds/speeds to extend life. When milling thin walls or small features, reduce axial depth and use climb milling where applicable to minimise deflection.
