Are metric auger bits available?
It would seem they must have been standard in Europe and Asia.

Jim,
I expect there are but remember UK was very late going metric and it was the major tool maker.

Are you joining the modern world and going metric?
No, it is just an easy way to drill a 25/64" hole is with a 10mm bit.Are you joining the modern world and going metric?

Star-M and Wood Owl make metric auger bits. I have both ...
Wood Owls at the rear ...
The Star-M bits are augers for use in a drill press.
The Wood Owls are the best augers on the market, with three cutting edges ...
Both come from the same manufacturer, as far as I am aware, based in Japan.
Google for Star-M.

Hmmm...may go back and re-measure those older bits, some time. Since they were made and labeled in sixteenths...as in a #4 would have been a 4/16". throw in a few decades of wear, clean-ups, and more wear..
A #5 bit...measured 1/4" between the spurs...but did not reach all the way to 5/16" ...about a 1/32" shy of 5/16".
Same with a few others I checked...
Most of my auger bits measure a few thousandths over their specified size. Some of my bits are right on. Dowelling bits were made exactly to size.
Improperly sharpened bits may be a little smaller at the spurs when someone files the outsides of the spur. These will often bind when boring a deep hole.
A 10mm bit suits my needs for a 25/64" equivalent. A good auger bit, used carefully can leave a cleaner hole than a twist drill bit.
