(Sandvik Coromant U.S.: Mebane, NC) – Sandvik Coromant, a global leader in metal cutting tools and solutions, is expanding its versatile CoroCut 2 with a new -GL parting and grooving geometry and an updated -CR parting-off geometry. The new and updated geometries increase chip control in long-chip material and provide a strong edge for high-feed parting-off.

Sandvik Coromant continues to develop its long-established parting and grooving concept, CoroCut 1-2, known for its high performance and security across a variety of applications. CoroCut 2 increases productivity and overall efficiency by maximizing output while minimizing energy consumption and waste. This expansion in geometries will make a significant difference to workshops machining hard-to-chip steels and in parting-off operations where a strong edge is needed.

Featuring the most aggressive chip breaker in the CoroCut 2 concept, the new
-GL geometry is ideal for workshops requiring better chip control in demanding ISO P components, such as low-carbon steel, clean steels, and cold-forged automotive components.

Jenny Claus, product manager of the parting and grooving division at Sandvik Coromant, says, “It’s no secret that good chip control will help you boost efficiency and avoid costly machine stops. But not just any insert will master this kind of material. This geometry has been developed to solve that problem.”

The -GL geometry also provides security that paves the way for increased automation.

“Shorter chips lead to less tangling and fewer stops, minimizing the need for manual handling and enabling more automated processes,” says Claus.

The -CR geometry is the first choice for parting-off operations at higher feeds or during intermittent cutting, and it’s suitable for a wide range of materials. With its strong edge and wiper design, it increases productivity and ensures excellent component quality.

Fredrik Selin, product application specialist at Sandvik Coromant, says, “All of our parting geometries feature this wiper design. It allows you to machine components at high feed rates without sacrificing surface finish and chip-breaking capabilities. A general guideline is two times the feed rate, same surface finish. Same feed rate, twice as good surface finish.”

When it comes to parting and grooving operations, stability is key. The main challenge is securing the insert to minimize any movement. Both the -GL and
-CR geometries feature Sandvik Coromant’s well-established rail interface, ensuring a more precise insert position and reducing movement for enhanced stability, especially when side forces are applied. Additionally, both geometries are produced with Sandvik Coromant’s patented FlashLight technology, generating higher quality and a more consistent edge line, resulting in superior and predictable tool life.
