Sandvik Coromant Introduces New Inserts

Sandvik Coromant has debuted new, double-sided negative inserts that feature four cutting edges and are designed for roughing/finishing in steel, stainless and duplex stainless steel, HRSA, and titanium.

The second-generation CoroTurn Prime B-type inserts are available for external and internal turning in a range of high-performing grades, including the new steel turning grades GC4415 and GC4425. Programming support is available in the most common CAM platforms and with CoroPlus Tool Path for PrimeTurning.

Since its 2017 introduction, PrimeTurning has been considered the biggest innovation in turning, since turning. The method enables turning in all directions and is a productive and efficient alternative to conventional machining. The concept comprises the PrimeTurning method, CoroTurn Prime A- and B-type tools and the CoroPlus Tool Path for PrimeTurning software.

The second-generation CoroTurn Prime B-type tools have undergone a major upgrade. “We are continuously working on developing our PrimeTurning offering,” said Staffan Lundström, product manager at Sandvik Coromant. “The new B-type tools are improved in all aspects to further support all-directional turning.”

A key benefit is that the new insert is negative and double-sided. Four cutting edges—twice the edges compared to the previous insert—allow more cost-efficient machining. The tool is also equipped with a new robust tip seat design, which prevents tool breakage if the insert breaks and enables shifting of feed directions without insert movements. Furthermore, the geometries are updated for better chip control even in very challenging materials, such as duplex stainless steel and ductile steels.

Comprehensive test results have shown productivity increases ranging from 50% to more than 100%.
