Product Overview

This high-performance bull nose end mill is designed for precision finishing operations in steel, alloy steel, and hardened metals (up to HRC60+). Featuring a TiSiN coating and 4-flute design, it delivers exceptional wear resistance, extended tool life, and superior surface finishes in demanding CNC milling applications.

Key Features
  • Premium Carbide Material - Ultra-fine grain carbide substrate for high rigidity and thermal stability
  • TiSiN Coating - Enhances hardness (up to 3500 HV) and oxidation resistance
  • Optimized Geometry - 45° helix angle reduces vibration and improves chip evacuation
  • R2/R3 Corner Radius - Strengthens cutting edge while maintaining precision
  • 4-Flute Design - Balances efficiency and finish quality
  • Bull Nose Tip - Ideal for semi-finishing to finishing operations
Performance Advantages
  • Extended tool life with reduced friction and wear
  • Superior surface finish with minimized burrs
  • Versatile for both roughing and finishing operations
  • Optimized for high-speed cutting (HSC) applications
Typical Applications

Materials: Carbon steel, alloy steel, tool steel, stainless steel (annealed), hardened metals (HRC45-60+)

Operations: Profile milling, 3D contouring, mold/die finishing, rib machining, precision slotting

Industries: Aerospace, automotive, mold & die, general metalworking
