VBHC-R8-BC3-I BORING HEAD C-TYPE imperial

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 now become an integral part of the body. The direct reading adjusting screw is ground after hardening and a plainly marked dial face in and adjustments of 0.01 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.
