A holder provided for mounting of a lathe cutter includes a carrier, a first joint seat, a second joint seat, a limit rod and a clamp member. The first and second joint seats are disposed on a first and second base of the carrier respectively. The lathe cutter is mounted between the first and second joint seats. The limit rod is inserted into a through hole of the lathe cutter, and a first and second ends of the limit rod are coupled to the first and second joint seats respectively. The clamp member is disposed on the limit rod. The clamp member and the second joint seat are provided to clamp the lathe cutter to separate the lathe cutter from the first and second bases.

A clamping member in a non-limiting aspect of the present disclosure may have a columnar shape extended from a first end to a second end. The clamping member may include an upper jaw, a lower jaw and a pocket. The upper jaw and the lower jaw may be located away from each other. The pocket may be located between the upper jaw and the lower jaw. The upper jaw may include a first member and a second member. The second member may be located closer to the first end than the first member. Hardness of the first member may be first hardness, and hardness of the second member may be second hardness. The first hardness may be different from the second hardness.

A toolholder assembly includes a toolholder having a rearwardly facing toolholder shank, a base member having a bore configured for receiving the toolholder shank, a lock rod with an axial forward and an axial rearward end, at least one locking member in communication with the axial forward end of the lock rod, and a flexible canister configured for receipt in the bore of the base member. The flexible canister includes at least one flexible feature that reduces a stiffness (i.e., increases flexibility) of the flexible canister. In one aspect, the flexible feature is a slot proximate a locking passageway of the canister.
