Anybody know where I can purchase round cutters for cutting the round parts of f holes? I can't find any in the UK and the internet hasn't turned up anything yet. Perhaps I'm not using the right terminology?
Any help would be appreciated.

David,
I see item W026-T-255 F-hole Drill set for $98.50 on the International Violin web site International Violin.
I also see it from DICK Tools in Germany. 73,08 EUR (incl VAT)
Item 701110 DICK GmbH
I've listed the English version of the web site, but there is also a German version at Dick GmbH Germany
Hopefully this is what you are looking for.
Kevin

I use spur bits. They're normal drill bits sharpened so that the outside edge forms a cutting spur. The ones that are sold commercially aren't really sharp enough to do the job, but once you've seen one, it's easy to figure out how to make one from a normal bit by using the corner of a grinding wheel.
There's one illustrated here:
http://en.wikipedia.org/wiki/Drill_bit
It's gold-colored, on the right of the page, a little bit down the page. As they point out, another name for it is "brad point". Use them in the drill press, and they do an extremely clean job.
Here's another photo:

I just found in my latest catalogue that Japan Woodworker sells bits which are sharp enough to do the job, and also provides excellent photos, if you want to make them yourself. The only difference with home made is that instead of a flat bottom between the inside and outside you'll have a V-shaped bottom, from the corner of your grinding wheel.

If you choose to go the route of drill bits then I think it will be hard to top these babies....

Here is a page with an explanation about lipped brad point bits:

I hope that this helps.
