Solid carbide end mill FANAR FREZ TRZPIENIOWY WEGLIK FI 12.0 26/83 Z3 HA12 VHM AT X‑MILL 345 R345

Solid carbide end mill FANAR FREZ TRZPIENIOWY WEGLIK FI 12.0 26/83 Z3 HA12 VHM AT X‑MILL 345 R345 is a 12.0 mm diameter, 3‑flute milling cutter designed for precision metalworking on CNC machines. Constructed from cemented carbide (VHM) with an AT coating and HA12 geometry, this end mill is intended for the X‑MILL 345 series and delivers consistent performance for slotting, profiling and finishing operations. The tool geometry and number of flutes balance chip evacuation and surface finish to meet typical machining tolerances in steel and non‑ferrous materials.

Advantages

The combination of VHM material and AT coating enhances tool life and wear resistance during continuous and interrupted cuts. Three flutes provide a compromise between material removal rate and chip clearance, supporting stable cutting in through‑cut and shallow slot applications. HA12 geometry optimizes cutting edge strength and reduces cutting forces, resulting in predictable tool behaviour and improved surface quality without compromising dimensional accuracy.

Suitable for (tasks / use cases)

• Slotting operations in steel and non‑ferrous alloys
• Profiling and contour milling on CNC machining centres
• Finishing passes to achieve required surface roughness
• Light to medium depth milling and semi‑finishing

Key specifications

• Material: cemented carbide (solid carbide)
• Diameter: 12.0 mm
• Number of flutes: 3 (Z3)
• Geometry code: HA12
• Coating: AT
• Series compatibility: X‑MILL 345

How to use

Mount the end mill in an appropriate collet or tool holder compatible with the X‑MILL 345 series and ensure proper runout and clamping. Select cutting parameters (spindle speed, feed per tooth, depth of cut) based on workpiece material and machine rigidity; start with conservative values and adjust for optimal chip formation and surface finish. Use appropriate coolant or air blast where recommended to manage heat and evacuate chips. Inspect the cutting edges periodically for wear and recondition or replace the tool when dimensional or surface quality requirements are no longer met.

Usage recommendations

For steel machining, reduce feed per tooth and depth of cut compared with aluminium to prolong tool life. Ensure effective chip evacuation with three‑flute tools by adjusting feed and coolant direction; avoid excessive dwell at the part to prevent built‑up edge formation.
