Installation Notes

Installation is performed by a qualified machinist or toolroom technician during insert indexing or toolholder service. Ensure the toolholder is removed from the machine spindle and all motion has stopped before servicing the clamp. Use the correct S532 clamp screw and appropriate torx or hex key as specified by the toolholder manufacturer. Do not substitute clamp screws of a different series, as improper clamping force can cause insert movement or ejection during cutting.
