Roughing, Finishing Aluminum-Specific End Mill Line Expansion

Cutting tool specialist Sandvik Coromant is expanding its line of CoroMill Dura versatile solid end mills with aluminum-specific tools. The concept, originally introduced in November 2022, is well suited for roughing and finishing, giving it a variety of uses for industries like mold and die.

“Stable cutting, small burr, good surfaces and minimal vibration is a combination that’s hard to beat for a versatile end mill like this,” Antti Wikström, global product manager, solid end mills, at Sandvik Coromant, says. “One of the main advantages of the new CoroMill Dura aluminum-specific end mills is their versatile performance in all different types of roughing applications, while also offering finishing capabilities. Up to 2×D full slot, pocketing, 5-20-degree ramping, shoulder milling and more — all with the same end mill.”

Another advantage is Sandvik Coromant’s WhisperKut helix concept, in which each flute is carefully oriented, unequally spaced from the others and has its own individually adapted helix angle, effectively breaking up harmful harmonics. This design is meant to eliminates vibration, resulting in quiet, safe and efficient machining.

The standard assortment offers diameters from 2-25 mm, depths of cut between 1.5-3×D, neck options, extended reach cutters, and sharp and corner radius styles. Tailor Made options include coated grades for more abrasive aluminums, specific diameters, corner designs and shank options.

To make tool selection easier, an online CoroPlus Tool Guide assists with tool and cutting data recommendations. “With the CoroPlus Tool Guide for CoroMill Dura, we can give the most accurate starting values for a specific application,” Wikström says. “And, if you have CAM software with the CoroPlus Tool Guide plug-in, it makes it even easier — you get the most relevant cutting data recommendations directly into your CAM program.”
