>Far circuits sells carbide tipped PCB drills with large (1/8?) shanks, but they're way too expensive from them. I'm looking for cheap ones, but not unusably cheap Chinese ones. Something like Enco house brand quality (no, I didn't check Enco). What do people who do this a lot buy?
Harbor Freight has an assortment, resharpened, of about 20 for roughly
six dollars. That's both on line and in the stores if they still
carry it. Now if you go online to HF, they (at one time) had a larger
assortment for only a few dollars more. Bear in mind that you will be
getting a good number of unusable drills (because of size) if you try
this approach. On the other hand, you may find this useful.
the 1/8 inch size is an industry standard. I'd recommend something
other than a dremel, since the runout on a dremel is worse than that
on a Proxxon. The 12 volt version of a proxxon will work, but I like
the 120 volt better.
