Metal-cutting specialist and manufacturing solutions provider Sandvik Coromant introduces CoroTurn PI®, a new family of internal turning tools combining precision chip breaking, all-directional turning and a unique tool holder design to unlock significant productivity gains. Designed for high process security, the tool concept is ideal for demanding operations in ISO P, ISO M and ISO K materials.
Machining internal features such as holes in shafts, ring gears or connection hubs presents several challenges. Vibration, deflection and chip build-up are common issues that can compromise both productivity and quality. CoroTurn® PI addresses these challenges with a high-precision chip breaker, multiple coolant configurations and support for both roughing and finishing operations in a single tool, delivering quality and efficiency in demanding internal turning applications.
“This tool is all about process security,” says Sascha Bolling, Global Product Manager at Sandvik Coromant. “Internal turning is complex, but a dedicated tool like CoroTurn® PI will not only prevent cutting issues, it will also boost your productivity, output and cost-efficiency.”
At the heart of CoroTurn® PI is a unique tool holder design with two separate insert seats, one for roughing and one for finishing. That means fewer tool changes, reduced cycle times and higher output. “We saw an opportunity to increase efficiency immensely with the dual insert seat design,” says Åke Nilsson, Global Product Application Specialist at Sandvik Coromant. “I haven’t seen another turning tool with this functionality and level of performance.”
What’s more, each roughing insert comes with eight cutting edges, boosting tool life and driving down cost.
CoroTurn® PI utilizes the patented PrimeTurning™ method, where small entering angles and all-directional turning deliver flexibility and control. The small angles, paired with the tool’s precision chip breaker, enable secure chip evacuation despite the limitations of internal features. To further optimize performance, the tool comes with customizable coolant delivery options, tailored for components with blind or through holes. The result is better chip control, smoother machining and greater reliability.
