Sandvik Coromant’s CoroMill Dura in action.
Sandvik Coromant has introduced a new range of high-end solid end mills.
The CoroMill Dura will replace the existing CoroMill Plura end mills. The concept is developed for roughing to finishing with different engagements in all applications and materials.
What makes the CoroMill® Dura different from the former version and competitors is its 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.”
Sandvik Coromant also says it has simplified the process of choosing the correct tool from th full range of solid end mills presented in the offering. “We have put a lot of effort into tool selection. Finding the right tool within the CoroMill® Dura assortment should never be a struggle,” Groppe says.
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 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.
