Product Overview

This industrial-grade 12mm bull nose end mill features a 150mm overall length (OAL) with 70mm cutting length, specifically engineered for deep cavity machining in hardened materials up to HRC65. The advanced TiSiN (Titanium Silicon Nitride) nano-composite coating provides maximum thermal protection in challenging applications.

Key Features
  • Extreme Reach Capability: 150mm OAL / 70mm cutting length with special neck relief design to prevent rubbing while maintaining rigidity at 5:1 length-to-diameter ratio
  • Nano-Layered TiSiN Coating: 1000°C+ thermal barrier protection with 5-8X longer life than standard AlTiN and self-lubricating properties to reduce built-up edge
  • High-Precision Carbide Substrate: Sub-micron grain structure (0.3-0.5μm) with optimized core strength (92.5 HRA) and ground to aerospace tolerances (±0.008mm)
  • Vibration-Dampened Geometry: Variable helix (37°/42°) with unequal flute spacing (82°/98°) and R1 radius to maintain corner integrity
Performance Advantages
✓ Longer Tool Life: AlTiCrN coating drastically reduces wear in abrasive materials
✓ Higher Productivity: 5-flute design enables faster machining with excellent surface finish
✓ Reduced Vibration: Engineered flute geometry minimizes chatter in hard materials
✓ Versatile Application: Effective in dry, wet, or MQL (Minimum Quantity Lubrication) machining
Recommended Applications
  • Deep Cavity Machining: Mold cores & ejector pockets, turbine blade root features, automotive die cavities
  • Aerospace Components: Engine casing grooves, landing gear structural pockets, wing spar channels
  • Medical Manufacturing: Orthopedic implant contours, surgical instrument profiles, dental mold details
