Product Description

Our 3.7mm 4-flute carbide flat end mill is precision-engineered for high-performance steel machining applications. Manufactured from ultra-fine grain tungsten carbide and available with advanced TiCN or AlTiN coatings, this end mill delivers exceptional durability and precision in the most demanding CNC operations.

The optimized 4-flute design provides the perfect balance between material removal rate and surface finish quality, making it ideal for mold making, die manufacturing, and general precision machining of carbon steels, alloy steels, and hardened steels up to HRC 55.

Features
1. Superior Tool Geometry
  • True 4-flute design for balanced cutting forces and reduced vibration
  • 30° helix angle optimizes chip evacuation in steel alloys
  • Precision ground cutting edges (±0.005mm) for consistent performance
  • Flat bottom design with <0.1mm corner radius for accurate profiling
2. Advanced Material Technology
  • Sub-micron carbide substrate (0.5μm grain size) for maximum toughness
  • Coating options:
    • TiCN (Titanium Carbonitride) - Ideal for general steel machining
    • AlTiN (Aluminum Titanium Nitride) - For hardened steels (HRC 45-55)
  • Polished flutes minimize chip adhesion in gummy materials
3. Performance Advantages
  • 3-5× longer tool life vs standard HSS end mills in steel
  • 20% higher feed rates enabled by optimized flute geometry
  • Superior surface finish (Ra 0.8μm achievable)
  • Reduced power consumption through efficient cutting design
4. Customization Options
  • Special diameters: 3.5-4.0mm available (±0.01mm tolerance)
  • Cutting lengths: Standard (3×D), Long (5×D), Extra-Long (8×D)
  • Shank configurations: Straight, Weldon flat, HSK compatible
  • Special geometries: Variable helix, reduced neck
