The cutting data above is an initial recommendation and depends on the machine condition, workpiece profile and the application clamping A relief groove is highly recommended, if not possible a gradual volume decrease should be made at the end of the broaching groove
The HK tool must be positioned outside of the hole/groove before each stroke After setup and first stroke, we recommend to observe the tool and the application to make sure no collision occurred
