You should run carbide drills quite fast. 30000 RPM is not too fast for
them.
A regular drill press is on the slow side in any setting, and might even
have too much runout.
I bought them bits via ebay germany, don't remember the seller. Asked
off-auction for what i needed and got a reasonable price so bought direct.
Just search ebay, you want used bits that have been replaced in cnc
machines routinely way before they were properly dull they are dirt cheap.
Also, avoid assortments with sizes smaller than 0.6 you don't want to use
them and they are plentiful 'cause of vias. Better get a seller where you
can select sizes. I must have paid something like 0.2eur per bit.
