Installation Notes

Installation is performed by machinists or toolroom technicians during routine insert indexing or replacement. Always ensure the machine spindle is fully stopped and the toolholder is removed from the machine before replacing insert clamping screws. Use only the specified C KEY Torx driver to avoid stripping the T6 drive recess. Do not substitute a standard hex or slotted driver.
