Features

This general-purpose insert is engineered for steel machining and is fully compatible with throw-away grooving and cut-off tool holders. Therefore, it delivers consistent cutting stability and precise groove formation across a wide range of steel processing tasks. Because it is equivalent to the insert included with No. 66705, it ensures direct compatibility and dependable replacement performance. Moreover, its durable edge design supports reliable wear resistance and efficient chip control, which enhances surface finish and operational efficiency. To replace the insert safely and accurately, a separate insert replacement tool No. 66750 is required. As a result, you maintain secure installation, stable clamping force, and high-precision cutting performance in demanding grooving and parting applications.
