Solid Carbide End Mill FANAR FREZ TRZPIENIOWY FI 1.0 mm, Ø4.0/50 mm, Z4, HA4, VHM, X-MILL 440N

Solid carbide end mill FANAR FREZ TRZPIENIOWY X-MILL 440N with a 1.0 mm shank/core and a nominal diameter of 4.0 mm is designed for precision milling tasks on metal and alloy workpieces. The tool has an overall length of 50 mm and four flutes (Z4) with HA4 geometry, produced from VHM (tungsten carbide) to provide high rigidity and consistent cutting performance in CNC machining operations.

Advantages

The X-MILL 440N combines solid carbide construction and HA4 flute geometry to deliver stable chip evacuation, improved surface finish and extended tool life compared with high-speed steel alternatives. Its 4-flute configuration allows for balanced cutting forces and finer axial engagement, while the 1.0 mm core increases torsional strength for small-diameter milling. The tool’s design supports repeatable accuracy and dimensional stability in series production and fine finishing passes.

Suitable for

• Precision slotting and profiling in steel and non-ferrous metals
• Finishing and semi-finishing passes on machined components
• CNC milling of small features, pockets and contours
• Operations requiring high rigidity and repeatability

Key specifications

• Material: solid tungsten carbide (VHM)
• Shank/core diameter: 1.0 mm
• Nominal cutting diameter: 4.0 mm
• Overall length: 50 mm
• Number of flutes: 4 (Z4)
• Flute geometry: HA4

How to use

Mount the end mill in a properly sized collet or tool holder that secures the 1.0 mm core to avoid runout. Select appropriate spindle speeds and feed rates for the workpiece material, starting with conservative parameters and increasing as tool performance and surface finish allow. Use proper coolant or lubricant according to the material being machined and the machine’s capabilities. Monitor tool wear and inspect part tolerances periodically to maintain repeatable results.

Usage recommendations

For best results, use this solid carbide end mill in rigid machine setups with minimal runout, apply interrupted cut strategies cautiously, and ensure adequate chip evacuation. When machining hardened or abrasive alloys, reduce feed per tooth and verify coolant compatibility to prolong tool life.
