This combination is ready to go to work for you. Criterion has been the choice tooling for boring applications since their start in 1935. Time tested and proven. Very lightly used, very minimal wear noticeable. As machinists, we can probably get the job done with what we have. Having nice tooling makes the job that much easier. This type of tooling is the one that will make you a return on your investment and make it easy.

*CUSTOM BUNDLE*

With this bundle you will get the boring head and Criterion CB3-CV50 tool holder. All screws and adjustment screws move without issue. Shank diameter is 2.98”. Total range for the boring head is 3” to around 5”. Threaded extension looks to be shop made but very rigid, 5.28” long. The marks you see on the head were from me. This thing was very tightly screwed together, so much so that I broke three spanner wrenches getting it apart.

Orders over $600 require signature at delivery unless otherwise specified. I want to make sure this tool gets to where it needs to go. Orders ship next day, I have added two shipping options for your convenience. Shipping and returns are free. I will make sure this is packed for the worst so it arrives to you in the best. Please review all pictures. Any questions, I’m more than happy to help. Thanks for looking!
