> And 1/32" size seems perfect for what I want

For general purpose boards 1mm / 1/32 is fine for just about
every electronic component. 1.2mm and 1.5mm HSS are handy
for various h/w

I must say I abuse my 1mm cobalt bit above and beyond the call
of duty and it's coming up for 10 years old

It gets used carefully as a milling bit, on an angle, for slots (eg PCB-
mount audio and DC connectors) and as a cutter for trimming tracks.
All hand-held. But I'd probably not attempt that with a thinner bit
unless it was considerably shorter
