Features

This general-purpose insert is designed for steel machining and is fully compatible with throw-away grooving and cut-off tool holders. Therefore, it delivers stable cutting performance and precise groove formation in a wide range of steel processing applications. Because it is equivalent to the insert included with No. 66704, it ensures seamless replacement and consistent machining quality. Moreover, its durable construction supports reliable edge retention and controlled chip evacuation, which enhances surface finish and overall efficiency. To replace the insert correctly and securely, a separate insert replacement tool No. 66750 is required. As a result, you maintain proper installation, dependable clamping stability, and accurate cutting performance throughout grooving and parting operations.
