Collection: 3+ Flute End Mills
3-flute and higher-flute end mills are optimized for rigidity, surface finish, and precision cutting, particularly in harder materials and finishing operations.
Additional flutes increase tool strength and place more cutting edges in contact with the material, resulting in smoother finishes, improved dimensional accuracy, and better performance in steel, stainless steel, and other harder alloys. These tools excel where stability and surface quality matter more than maximum chip evacuation.
2-Flute vs 3+ Flute — when to use each
Best suited for:
- Steel, stainless steel, and harder alloys
- Finishing passes and light to moderate material removal
- Applications requiring improved rigidity and reduced tool deflection
- High-precision profiling and contouring
- Situations where surface finish is critical
Use the filters below to narrow results by diameter, flute count, geometry, and cut direction to match the tool to your material, machine capability, and cutting strategy.
