Hello: Rhaney2

I am in the tool sharpening business. As a vocation but I do have it as a part time business. I can sharpen tools but do not have expertise in the topic of your question.

With that in mind, to help you obtain the answer to your question, I am copying it into the tools forum.

Check on your question in that forum. I am sure there will be an expert to answer your question.

You might want to contact a local machine shop or look for a Tool grinder shop, ie; someone who re-sharpens carbide endmills for the machine shops. To cut carbide you need to use a diamond grinding wheel, now if they have anything that small is a different story.

I went to a tool supply web site, MSC. Here is a link to the page I found the tool on that you could use, it is on the right side of the page. They don't have the exact size if I recall, but one that is smaller that could be use to open the hole up. I must tell you that it will still be hard to do without the equipment to hold the die and the diamond tool.

Good luck

If you are enlarging an existing hole and want reasonable acccuracy in the final opening you need to ream it out rather than drill it. A drill maintains its center with the tip. If you put a bit into a hole that is close to the bit's size it will wander.
With the proper tools this would be a snap but for one hole it may not be worth the cost.
A machine shop might be your best bet as comtnman suggested.
