| Here is a sturdy unit of extended boring range, capable of peeling off heavy roughing cuts as well as a tool of extreme sensitivity. The use of a wide base bar holder, resting securely on the body, eliminates the need for a separate side plate. You will note this has become an integral part of the body. The direct reading adjusting screw is ground after hardening and a plainly marked dial face in non-reflecting satin chrome allows easy reading and adjustments of .0005 or less. All CRITERION boring heads have threaded backs for use with a variety of shanks. This model takes a 1-1/2-18 Threaded shank. Has a cross hole diameter of 3/4,and center distance between holes of 15/16. |
