New Solid End Mills Assortment Applicable for Cutting Molds, Dies

Cutting tool and tooling system specialist Sandvik Coromant is introducing a new range of high-end versatile solid end mills. The 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, giving it a variety of uses for industries like mold and die.

According to Dr. Markus Groppe, global product application manager at Sandvik Coromant, what makes the CoroMill Dura stand out compared to the former versatile concept and competitor end mills is its WhisperKut 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,” Groppe explains.

Another notable feature is the ease in which users can choose the correct tool within the comprehensive range of CoroMill Dura solid end mills. 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.
