Anyone know where I can buy a 9mm (not 3/8") Forstner or sawtooth
bit in the
UK?



I'm a little surprised in the fact +0.52mm isn't accurate enough for
you.

However, I wondered if you'd considered a 9mm spade bit for your
task?
They're more readily available, all indicators on Screwfix and
Axminster led to a 3/8ths size bit, for the forstner bit. Rutlands
who I consider at the top end of the British market also only do
either a 3/8ths or 8 and 10mm forstner bit.

I feel you may have to compromise, or, have your own bit milled to
exact specifications?


Just curiosity mixed with perfectionism. I have some 9mm rare earth
magnets I'm using to make door catches. They fit perfectly snugly
into a 9mm hole and are loose in a 3/8" one. A 9mm brad point drill
does the job nicely but is too long to give clearance under the
drill
press for the edge-on wood.

Uh, why not just cut off a brad-point bit to the length you need? 30
seconds with a Dremel and you're done.

Mainly becasue if I'd done that with the only 9mm brad point I had to hand I
would have ended up trying to grip the flutes in the chuck!


FWIW, googling "metric forstner bit" showed many sources for 10mm and
larger, and one set with 6mm, but no 9mm--the set jumps from 6 to 10.

Yes - that's what I found. Just wondered if anyone knew better.

Anyway, problem solved now
