I’ve got some older heads that I have to bore to .370. Do I use the .355 reamer for this or the .370 reamer listed on the Canadian site. I might purchase the hand chuck as well. I’ve never done this before so it’s a little touch and go. Any tips are very welcome.
Customer wants his heads to accept .370 graphites. Not a whole lot of economical choices in .355 graphite. Many thanks

We prefer to use the T bit, then the U bit, then the 3/8 bit. Start with the T and drill all the way to the bottom, then the U bit all the way to the bottom, then the 3/8 all the way to the bottom. It’s usually easier to do it that way, but it does take a little more time. We highly recommend it be done with a drill press and a jig to hold the irons hosel perfectly vertical. The bore really has to be perfectly centered for it to yield the necessary result.
You can just skip all that and use a 3/8′ drill bit or the .370″ reamer, but it’s more difficult as your trying to cut all the material at once.
