FANAR solid carbide end mill X-MILL 440N, 8.0 mm diameter, 19/63 mm, Z4, HA8 coating

FANAR solid carbide end mill X-MILL 440N with an 8.0 mm cutting diameter is a four-flute milling cutter designed for general metalworking and precision milling. With overall dimensions 19/63 mm and HA8 surface treatment, this tool is intended for slotting, profiling and finishing operations on CNC machines and conventional mills. The solid carbide construction provides rigidity for stable cuts and consistent dimensional accuracy.

Advantages

The X-MILL 440N combines a four-flute geometry with a wear-resistant HA8 coating to extend tool life and improve surface finish on a range of metallic materials. Its solid carbide body offers high stiffness for reduced vibration and reliable tool performance at moderate to high spindle speeds. The cutter’s balanced flute design promotes efficient chip evacuation and consistent cutting forces for repeatable results in serial production and single-part machining.

Suitable for

• Slotting and pocketing in steel and non-ferrous metals
• Profiling and contour milling on CNC machining centers
• Finishing passes to achieve tighter surface roughness
• General-purpose milling where tool life and surface quality are required

Key specifications

• Cutting diameter: 8.0 mm
• Overall dimensions: 19/63 mm (cutting length/overall length)
• Number of flutes: 4 (Z4)
• Material: solid carbide
• Surface treatment: HA8 coating for increased wear resistance

How to use

Install the end mill in a compatible, properly tightened toolholder and verify runout prior to machining. Select cutting parameters appropriate for the workpiece material, taking into account spindle speed, feed per tooth and depth of cut recommended for four-flute carbide cutters. Use coolant or compressed air as appropriate for chip evacuation and temperature control. For slotting or heavy material removal, reduce axial engagement and make multiple passes rather than a single deep cut to preserve tool life.

Usage recommendations

Use balanced spindle speeds and conservative feed rates during initial cuts to confirm tool behavior and adjust parameters based on observed surface finish and tool wear. Regularly inspect the cutting edges and replace the tool once edge deterioration affects dimensional accuracy or surface quality.
