16mm 8 Flute Carbide Finishing End Mill High Precision CNC Milling Cutter for Steel Aluminum 45° Helix Angle Mirror Finish

Introduction:

Our 16mm 8-Flute Carbide Finishing End Mill is engineered for ultra-precise finishing operations in CNC machining. Designed with an optimized 45° helix angle and high-performance carbide substrate, this cutter delivers mirror-like surface finishes (Ra ≤ 0.4μm) on steel, aluminum, and alloys. Ideal for industrial applications demanding tight tolerances and smooth part aesthetics.s.

Features:

1. Premium Carbide Construction

• Material: Ultra-fine grain tungsten carbide (YG10X) for maximum wear resistance and edge retention.

• Hardness: 92 HRA, ensuring longevity even in hardened steels (up to HRC 50).

2. 8-Flute Design for Finishing Excellence

• High Flute Count: 8 flutes maximize surface contact for superior finish quality and reduced tool marks.

• Balanced Cutting Forces: Minimizes vibration for chatter-free operation at high RPMs.

3. 45° Helix Angle Optimization

• Smooth Chip Evacuation: Prevents chip re-cutting and workpiece damage.

• Reduced Cutting Resistance: Lowers power consumption and extends tool life.

4. Advanced Coating Technology

• TiAlN (Titanium Aluminum Nitride) Coating:

  • Increases heat resistance (up to 900°C).

  • Reduces friction by 25% vs. uncoated tools.

  • Extends tool life by 3X in abrasive materials.

5. Precision Engineering

• Tolerance: ±0.008mm for critical tolerance applications.

• Runout: <0.003mm ensures consistent finish quality.

• Edge Prep: 20° rake angle for clean shearing in non-ferrous metals.

Performance benefits:

✔ Mirror Finishes – Achieve Ra 0.2–0.4μm surface roughness without secondary polishing.

✔ High MRR (Material Removal Rate) – 8 flutes enable 20% faster finishing passes vs. 4-flute end mills.

✔ Multi-Material Versatility – Optimized for:

• Steel: AISI 1045, P20, H13 (HRC ≤50).

• Aluminum: 6061, 7075 (no built-up edge).

• Exotics: Titanium Grade 5, Inconel 718 (with reduced feeds).

✔ Cost Efficiency – Replaces grinding/polishing steps in mold/die production.

Applications:

• • • Aerospace: Turbine blade finishing, structural components.

• • • Automotive: Transmission housings, cylinder heads.

• • • Mold & Die: Cavity polishing, EDM electrode machining.

• • • General Engineering: Precision shafts, hydraulic components.
