Sandvik Coromant’s CoroTurn 300 is designed to increase component quality, handling efficiency and tool life in high-volume OD steel turning applications that require longitudinal and face-turning operations. The tool features stable insert clamping through the iLock interface. The system locks the insert in place to prevent cutting forces from affecting the tool position. iLock provides tool accuracy within ±0.05 mm (0.002"), giving the operator indexing repeatability for a better surface finish and increased tool life.

The CoroTurn 300 features eight-edge inserts with 80-degree cutting edges, which are available in GC4325 and GC4315 grades. The inserts feature Inveio coating, a uni-directional crystal orientation to increase wear resistance and tool life. According to the company, the design features excellent chip-breaking capabilities and less carbide per edge, which reduces environmental impacts and produces less waste.

The tool offers additional chip-breaking capabilities through high-precision over- and under-coolant. Coolant from above controls chip breaking for secure machining while under-coolant controls the temperature for extended tool life. The tool is also equipped with Coromant Capto interface in a variety of sizes, and Quick Start shanks, which enable quick tool changes and coolant connections to increase efficiency.
