DIY Drill press for Dremel type tool

Lateral play is critical. Given a drill bit 0.03" in diameter, 0.01" of lateral play can snap it.

As a hobby builder I drill FR-4 with steel bits. They dull more quickly, but they are cheaper and will not shatter when used in sloppy tolerance hobby tools. Carbide bits require collet chucks in very precise spindle bearings.
I use 1/32, (.032) diameter bits for most through hole construction. These cost about 50 cents each when purchased in 12 or 24 packs from buydrillbits.com. ( I have no financial interest in that company.) The 3/64 bits are used for larger component leads.
Numbered bits are more expensive

remember not to move the board itself.
The local prices of carbide bits are approximately 1.00 USD each, but
they will last a long time.
I do hand wired vias and mostly surface mount, so my requirements are
probably different than yours.

I found a small tabletop drill press (forgot what Proxxon called it) to hold my Proxxon IB/E rotary millilng tool vertical, so I can use it to drill holes in PCB.
IIRC, you can buy it from the vendor that sells the Proxxon tool. It works just like a drill press. It is also made by Proxxon. Haven't used it yet.
Still haven't got a laminator or heat press for toner transfer.
