BORING BAR BUSHINGS for CNC TURNING CENTERS

All straight BORING BAR BUSHINGS have two elongated holes to make them universally applicable for most machine tools.

They are hardened and precision ground on O.D., I.D. and the back of the flange.

By positioning the BUSHING on the boring bar and securing it in place with the socket set screw, pre-setting off the machine can be done.
