Introduction:

ID expansion clamps expand to self-center and clamp on the inside diameter of a workpiece, leaving the outside clear for machining. 

Tightening the tapered center screw of ID clamps with a hex wrench pushes the clamping segments outward, and slightly downward, to exert force on the workpiece's internal bore.

ID expansion Clamps allow close mounting for multi-part machining on vertical and horizontal machining centers.
