12mm TiSiN Coated Carbide Bull Nose End Mill R1 Corner Radius,
150mm OAL 70mm Cutting Length for Steel Hardened Alloys
Introduction:
This industrial-grade 12mm bull nose end mill features an extraordinary 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
where standard tools fail.
Features:
1. Extreme Reach Capability
150mm OAL / 70mm cutting length
Special neck relief design prevents rubbing
Maintains rigidity at 5:1 length-to-diameter ratio
2. Nano-Layered TiSiN Coating
1000°C+ thermal barrier protection
5-8X longer life than standard AlTiN
Self-lubricating properties reduce built-up edge
3. High-Precision Carbide Substrate
Sub-micron grain structure (0.3-0.5μm)
Optimized core strength (92.5 HRA)
Ground to aerospace tolerances (±0.008mm)
4. Vibration-Dampened Geometry
Variable helix (37°/42°) eliminates harmonics
Unequal flute spacing (82°/98°)
R1 radius maintains corner integrity
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.
