The chucks are designed for mounting on universal and special lathes. The design of the chucks provides high pressure force transfer with much less vise grip wrench torque compared to concentric jaw chucks. Wedge bar chucks have high wear resistance and long service life, stability in reaching high precision of centering parts. The chuck is made on the basis of a steel body, the grooves for the jaws are hardened with HDPE. This chuck has T-slots on the body for installation of various technological adjustments.
