4 Flute Solid Carbide 5mm square cutting end mill Flat Bottom CNC Cutting Tool for Steel Hard Metals
Introduction:
Our 5mm 4-flute solid carbide square end mill is engineered for high-performance machining of steels and hard metals (up to HRC 60). Featuring a precision-ground flat bottom and ultra-fine grain tungsten carbide construction, this industrial-grade cutting tool delivers exceptional rigidity, wear resistance, and surface finish quality in demanding CNC milling applications.
The optimized 4-flute geometry provides the ideal balance between material removal rate and tool life, making it perfect for mold/die manufacturing, aerospace components, and general precision machining where dimensional accuracy is critical.
Features:
True square end (<0.05mm corner radius) for sharp 90° shoulders
4-flute design maximizes feed rates while maintaining stability
35° helix angle reduces cutting forces and harmonics
Full-length cutting edges enable side-wall finishing
Sub-micron carbide substrate (0.6μm grain size)
AlTiN/TiSiN coating options (up to 3,800HV hardness)
Polished flutes prevent chip adhesion in gummy materials
✓ 4× longer life vs standard HSS end mills in 4140 steel
✓ 0.10mm/tooth feed rates achievable in alloy steels
✓ Ra 0.8μm surface finish in finishing passes
✓ IT7 tolerance maintained over full tool life
Diameter tolerance: ±0.005mm (h6) available
Length variants: 3×D, 5×D, 8×D cutting lengths
Shank types: Straight, Weldon, HSK, BT
Special geometries: Corner radius, variable helix
