Installation Notes

Installation is performed by machinists or toolroom technicians during toolholder setup or insert changeover on turning equipment. Power down or disable the machine and engage all safety locks before servicing the toolholder. Use the appropriate driver for the 1/4-28 clamp screw and ensure the XNS-47 screw is in serviceable condition before reuse. Do not substitute clamp screws of a different thread specification, as improper fasteners can compromise insert security during cutting.
