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 observing the tool and the application to make
sure no collision occurs.
