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:


1. Advanced Tool Geometry

  • 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


2. Premium Material Technology

  • 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


3. Documented Performance Advantages

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


4. Customization Options

  • 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


Applications:


① Mold & Die Industry

  • Precision cavities in P20, H13 mold steels

  • EDM electrode machining


② Automotive Components

  • Transmission gear machining

  • Engine block detailing


③ General Metalworking

  • Carbon steel fixture manufacturing

  • Alloy steel prototype machining


④ Tool & Die Maintenance

  • Die repair and refurbishment

  • Precision slot cutting
