AlTiCrN 5 Flute Carbide End Mill for Steel High Performance CNC Milling Cutter for Hardened Steel Stainless Alloys

Introduction:

The AlTiCrN Coated 5-Flute Carbide End Mill is a premium cutting tool engineered for high-efficiency machining of steel, hardened alloys, and stainless steel. Featuring an advanced AlTiCrN (Aluminum-Titanium-Chromium-Nitride) coating and 5-flute design, this end mill delivers exceptional wear resistance, extended tool life, and superior surface finishes in demanding CNC applications. The optimized geometry ensures reduced vibration, improved chip evacuation, and higher metal removal rates (MRR), making it ideal for both roughing and finishing operations.

Features:

✔ Ultra-Hard AlTiCrN Coating – Withstands extreme temperatures (up to 1100°C) and offers 3-5X longer tool life compared to standard TiN or TiAlN coatings.

✔ 5-Flute High-Efficiency Design – Balances chip load for smoother cuts, higher feed rates, and improved productivity in steel and tough alloys.

✔ Solid Tungsten Carbide Construction – Provides maximum rigidity, wear resistance, and edge retention for heavy-duty machining.

✔ Variable Helix & Pitch Geometry – Reduces harmonics and vibration, enabling stable performance at high RPMs.

✔ High-Feed Capable – Optimized cutting edges allow for aggressive machining without sacrificing tool life.

✔ Coolant-Ready – Compatible with high-pressure coolant (through-spindle or external) for better heat dissipation and chip control.

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.

Applications:

• Hardened Steels (HRC 45-65) – Tool steels (D2, H13), die steels, mold bases

• Stainless Steel (304, 316, 17-4PH) – High-efficiency milling with minimal work hardening

• Alloy Steels (4140, 4340) – Automotive & aerospace components

• High-Temp Alloys (Inconel, Waspaloy) – Turbine blades, engine parts

• General CNC Machining – Industrial parts, precision tooling
