FANAR solid carbide end mill M9-44GMA0-0080 8.0 mm diameter, 19/63 mm length, Z4, HA8 coating

FANAR solid carbide end mill M9-44GMA0-0080 is an 8.0 mm diameter VHM cutter engineered for precision milling operations. The tool features a 19/63 mm length specification with four flutes (Z4) and an HA8 surface treatment that improves wear resistance and extends tool life in metalworking applications. It is intended for general machining and finishing where a compact 8 mm solid carbide end mill with reliable geometry and coating is required.

Advantages

The four-flute geometry delivers a balance between material removal rate and surface finish, while the solid carbide construction provides rigidity and thermal stability under cutting loads. The HA8 coating reduces friction and increases resistance to abrasive wear, helping maintain consistent performance over repeated cycles. The tool’s overall dimensions and flute count enable stable cutting in a variety of feeds and speeds suitable for common milling setups.

Suitable for

• Profile milling and slotting in steel and non-ferrous metals
• Finishing passes requiring a smooth surface quality
• Machining in setups where an 8 mm diameter tool is standard
• CNC milling operations with moderate to high spindle speeds

Key specifications

• Cutting diameter: 8.0 mm
• Overall/working length: 19/63 mm (length specification)
• Flutes: 4 (Z4)
• Material: solid carbide (VHM)
• Surface treatment: HA8 coating for enhanced wear resistance

How to use

Mount the end mill in a compatible collet or tool holder ensuring correct concentricity and secure clamping. Select cutting parameters based on workpiece material, machine rigidity, and coolant availability; start with moderate spindle speed and feed and adjust to optimize chip formation and surface finish. Use appropriate depth of cut per pass to avoid excessive radial or axial loads that could reduce tool life. Apply coolant or air flow as recommended for the specific material to control heat and evacuate chips.

Usage recommendations

For best results, use the cutter for finishing and semi-finishing passes where stable tool engagement is possible. Monitor for signs of wear on the cutting edges and replace the tool when surface finish or dimensional accuracy degrades. When machining hard or abrasive alloys, reduce feed per tooth and increase coolant flow to prolong tool life.
