Installation Notes

Installation and toolholder changes should be performed by a qualified machinist or CNC technician with the machine in a powered-down, locked-out state per applicable machine safeguarding procedures. Secure the shank firmly in the tool turret or tool post to the machine manufacturer's specified clamping torque before operation. Inspect the insert pocket and screw before each insert index to confirm the seat is clean and the clamping screw is in serviceable condition. Follow the insert manufacturer's indexing procedure to avoid edge chipping during changeover.
