3 5 and 6 Flute End Mills

3 5 and 6 Flute End Mills


 

3-Flute Carbide End Mills

5-Flute Carbide End Mills

6-Flute Carbide End Mills

Advantages

  • Higher Chip Removal Rate: 3-flute end mills provide larger chip evacuation paths due to fewer flutes. This results in efficient chip removal, making them suitable for high-speed machining.
  • Enhanced Rigidity: With fewer flutes, these end mills offer greater rigidity, reducing the chances of deflection and vibration during heavy cuts.
  • Improved Chip Control: They are particularly effective in materials that produce long, stringy chips, such as aluminum, as they can better control chip formation.
  • Smooth Surface Finish: 5-flute end mills produce fewer tool marks and a smoother surface finish due to the higher number of flutes, which results in more contact points with the workpiece.
  • Enhanced Stability: They offer good stability during machining, reducing chatter and vibration, particularly in applications requiring precision and fine finishes.
  • Exceptional Surface Finish: 6-flute end mills provide even more contact points with the workpiece, resulting in an exceptionally smooth surface finish with minimal tool marks.
  • High Precision: They are excellent for precision machining applications where tight tolerances and high accuracy are essential.

Use Cases

  • Slotting and Roughing: Their rigidity makes them well-suited for slotting and roughing operations in various materials, including steel and stainless steel.
  • High-Speed Machining: The larger chip evacuation paths allow for higher cutting speeds, making them ideal for high-speed machining applications.
  • Finishing Operations: 5-flute end mills are excellent for finishing passes in materials like aluminum, stainless steel, and high-temperature alloys.
  • Hard Milling: They can handle hard materials like tool steel and hardened alloys while maintaining a high-quality surface finish.
  • Profile Machining: These end mills excel in profiling complex shapes and contours.
  • Finish Machining: 6-flute end mills are often used for finish machining of intricate parts, such as aerospace components and medical devices.
  • Contouring: These end mills excel in contouring complex shapes and intricate profiles.
  • High-Speed Machining (HSM): In applications requiring high-speed machining, 6-flute end mills can maintain precision and quality surface finishes.

 

45-Degree Helix

60-Degree Helix

End mills with a 45-degree helix angle are versatile and suitable for a wide range of materials and applications. They offer a balance between chip evacuation and rigidity. End mills with a 60-degree helix angle are designed for high-efficiency machining, especially in materials that are prone to work hardening. They excel in materials like stainless steel and heat-resistant alloys.
