Rough boring head shanks are designed to be used with boring heads in machining operations. They are typically made from hardened steel and feature a threaded end for secure attachment to the boring head. The shank has a solid body with a hole on the bottom for mounting onto the spindle of the machine. It also has a collar on the top for connecting the boring head to the shank. The end of the shank is usually tapered to fit the boring head securely. Depending on the application, different sizes of boring head shanks may be used.
