Model BT
The BT Adjustable boring tool is used in screw machines, turret lathes, and CNC lathes for fast set up when boring from the turret. A reversible eccentric bushing, furnished with tool, permits either right or left hand boring. The micrometer adjusting screw graduated in .001″ is used for close tolerances. Mating surfaces, bores and shanks are precision ground to assure parallelism and squareness.
