16mm 4 Flute 45° Helix Angle Carbide End Mill Bits Blue Nano Coated Flat End

Product Specification

16mm 4 Flute 45° Helix Angle Carbide End Mill Bits Blue Nano Coated Flat End Milling Cutter for Steel CNC Machine Tool

Introduction:

Our 16mm 4-Flute Carbide End Mill with 45° helix angle and blue nano coating is engineered for professional-grade CNC machining of steel, stainless steel, and hard alloys. This high-performance flat end milling cutter delivers exceptional precision, durability, and cutting efficiency, making it an essential tool for industrial metalworking applications.

Features:

1. Premium Carbide Construction

• Material: Made from ultra-fine grain tungsten carbide (YG8) for superior hardness and wear resistance.

• Rigidity: High rigidity design minimizes deflection during heavy cutting operations.

• Heat Resistance: Maintains cutting edge integrity even at elevated temperatures.

2. Optimized 45° Helix Angle Design

• Smooth Cutting: The 45° helix angle ensures gradual engagement with the workpiece, reducing vibration and chatter.

• Improved Chip Evacuation: Efficient spiral flute design allows for better chip removal, preventing chip re-cutting and tool clogging.

• Surface Finish: Produces superior surface finishes (Ra ≤ 0.8μm) in steel and tough materials.

3. Advanced Blue Nano Coating

• Coating Type: TiAlN (Titanium Aluminum Nitride) + Nano multilayer coating for extreme heat and wear resistance.

• Benefits:

  • Reduces friction by up to 30%, lowering cutting temperatures.

  • Extends tool life 2-3X compared to uncoated end mills.

  • Prevents built-up edge (BUE) on sticky materials like stainless steel.

4. 4-Flute Design for Balanced Performance

• Optimal for Steel: 4 flutes provide the ideal balance between material removal rate and tool strength.

• Versatility: Suitable for slotting, profiling, plunging, and contouring operations.

• High-Speed Compatibility: Stable performance at RPMs up to 12,000 (varies by machine).

5. Precision Engineering

• Tolerance: ±0.01mm for high-accuracy machining.

• Edge Preparation: Micro-grinding technology ensures razor-sharp cutting edges.

• Runout: <0.005mm for vibration-free operation.

Applications:

• • Steel & Alloy Machining: Carbon steel, tool steel, alloy steel (HRC ≤60).

• • Stainless Steel: 304, 316, 17-4PH, etc.

• • Hard Metals: Cast iron, titanium alloys, Inconel (with reduced parameters).

• • Industries: Automotive, aerospace, mold & die, energy, and general engineering.
