Cutting tool and tooling system specialist Sandvik Coromant is introducing a new range of solid end mills, the CoroMill Dura, which will replace the existing versatile CoroMill Plura end mills. The concept is developed for roughing to finishing with different engagements in all applications and materials.

CoroMill Dura features a WhisperKut technology. Markus Groppe, global product application manager at Sandvik Coromant, explains the unequal helix concept: “Each flute is oriented at a different helix angle, and every level of the cutting edge is unequally spaced from the others. This way, you can achieve very good stability and efficient machining without vibration.”

Included in the CoroMill Dura range is the four-flute plug-and-play solution, which is said to work for a wide range of applications. Additional tool variants are available for more specific operations, such as key slots, dynamic milling, semi-finishing and finishing. Further assistance comes from the CoroPlus Tool Guide for CoroMill Dura online tool selector, which supports slotting, side milling, pocketing and helical interpolation applications to make tool selection simpler.

The CoroMill Dura is available from two to seven flutes with 1-4 × D cutting length, with and without a chip divider. The end mills can be reconditioned up to three times to original specifications.
