FANAR solid carbide end mill X-MILL 430, diameter 2.5 mm, length 50 mm, 8/50 Z4 HA4 VHM

FANAR solid carbide end mill X-MILL 430, diameter 2.5 mm and overall/working length 8/50 mm, is a precision milling tool made from micro-grain solid carbide (VHM) with four flutes and HA4 geometry. The tool is intended for small-diameter milling operations where rigidity, dimensional accuracy and consistent chip evacuation are required. Its compact form and balanced flute design support high-speed CNC machining, slotting and finishing passes in a range of metallic and harder workpiece materials.

Advantages

The X-MILL 430 combines a micro-grain carbide body with a four-flute profile and HA4 geometry to deliver stable cutting performance, good surface finish and extended tool life in small-diameter applications. The 2.5 mm diameter offers access to narrow features and fine detail while the 8/50 mm length ratio provides a compromise between reach and rigidity. The flute geometry supports efficient chip removal and reduced vibration during high-speed rotation, improving dimensional repeatability.

Suitable for

• Precision CNC milling of small features and slots
• Finishing passes on hardened or tough metals
• Micro-machining and toolroom prototyping
• High-speed operations requiring rigid, small-diameter tooling

Key specifications

• Cutting diameter: 2.5 mm
• Overall/working length: 50 mm / 8 mm
• Number of flutes: 4 (Z4)
• Geometry: HA4
• Material: solid carbide (VHM), micro-grain
• Intended use: milling, slotting, finishing

How to use

Select appropriate spindle speeds, feed rates and depth of cut for the workpiece material and machine rigidity; small-diameter carbide end mills typically require higher spindle speeds and moderate feeds per tooth to avoid chipping. Ensure secure clamping of the workpiece and minimal overhang of the tool to maximize stiffness. Use appropriate coolant or air blast to aid chip evacuation when machining steels and other materials that create long chips. Inspect tool condition regularly and replace if wear or edge chipping is observed to maintain dimensional accuracy.

Usage recommendations

For best results with the FANAR X-MILL 430 2.5 mm solid carbide end mill, minimize tool overhang, optimize cutting parameters for the specific material, and use coolant or compressed air to improve chip flow. For finishing operations reduce axial depth of cut and increase spindle speed to achieve improved surface quality and tool life.
