High-performance turning insert for steel and stainless steel

The CCMT ... -HM RT300 is a versatile indexable turning insert specifically engineered for medium machining tasks. Thanks to its wear-resistant RT300 PVD coating, it is an ideal choice for universal turning applications in steel and stainless steel (M10-M25). The integrated HM geometry supports smooth chip breaking, contributing to stable machining processes even during light interrupted cuts. This makes the insert an economical and dependable tooling solution for professional daily operations.

Applications

The CCMT ... -HM RT300 is excellently suited for the medium turning of steel and stainless steel components. It demonstrates its full potential when manufacturing shafts, axles, and flanges where reliable chip control is required. Thanks to its toughness, it performs exceptionally well under both continuous and light interrupted cutting conditions, making it a flexible option for varying workpiece contours.

Special features

A key feature of this positive indexable insert is the RT300 PVD coating, which significantly enhances wear resistance when machining abrasive stainless steels. The combination of this advanced coating and the precisely designed HM chipbreaker reduces cutting forces and effectively prevents built-up edges. This not only promotes a superior surface finish but also ensures reproducible results in batch production.
