Are you looking for a shop to make these drill bits? or are you looking for someone to tell you how to do them? If you are looking for a shop to do them for you I work for a company whose main product group is medical drills and cutting tools. We are located in Michigan. If you wish for us to quote send me a PM and I will give you the email for our sales rep. About 99% of our parts are stainless steel. Our engineering group could even help you with your design if you wish. Here is our website if you wish to take a look.
