Sandvik Coromant is introducing a completely new range of high-end versatile solid end mills. CoroMill Dura 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.

What makes CoroMill Dura stand out compared to the former versatile concept and competitor end mills, is the WhisperKut technology. Dr. 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.”

Another noticeable feature is how easy it is to choose the correct tool within the comprehensive range of solid end mills presented in the offer. “We have put extremely high effort on the tool selection aspect. Finding the right tool within the CoroMill Dura assortment should never be a hustle,” continues Groppe.

First choice is the four-flute plug and play solution, which works 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 can also be given with the CoroPlus Tool Guide for CoroMill Dura online tool selector supporting the application areas slotting, side milling, pocketing and helical interpolation — all to make tool selection simpler.

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