Corner Radius End Mill

Recommended Corner‑Radius End Mills  4‑Flute, 

• 30° helix,  

• Perfect for light roughing/finishing with strengthened edges for improved lifespan.

3. Carbide Corner Radius

• Stub-length (1″ flute), corner radius adds durability—ideal for robust pocket finishing  India‑Available CARBITEC Series

• Ø 6 mm , 4‑Flute, 55HRC,

•  Technical Insights

• Coatings & Materials: Options span uncoated, TiAlN — suitable for a wide range of steels, cast iron, stainless, and non-ferrous materials 

• Helix & Flute Design: 30° helix provides balanced performance. Variable index and unequal-pitch designs  minimize chatter and improve finish 

• Corner Radius Benefit: Rounded corners significantly strengthen the cutting edge and extend tool life—effective starting radius ~0.005" for small cutters 

 Choosing the Right Tool

 Best Practices

1. Depth vs. Radius: Ensure both axial and radial depths ≥ corner radius to avoid rubbing and premature wear 

2. Coolant Strategy: Always use flood or mist—coatings hold up with or without coolant, but coolant extends tool life 

3. Minimize Overhang: Keep tool extensions short to avoid deflection and maximize finish quality.

4. Toolpath Setup: Combine roughing passes with smaller-corner cutters followed by finishing passes with larger radius for smooth transitions.
