Wasn't sure where I should post this, but thought this forum was the best fit...
With all of the holes I drill in the PCBs I make, I noticed that the little bits I had that came in a micro drill kit get dull really quickly and don't make the best holes (and sometimes would lift pads
). I didn't know that most places typically use tungsten-carbide bits for drilling PCBs because of their durability and strength, so when I found this out I tried finding some.
This place is where I went with:
http://www.drillbitcity.com/
or http://drillcity.stores.yahoo.net/ (they're both the same place, but this one offers 5pc of same size bits).
The prices seemed great so I ordered some (the new carbide ones, though I've read good things about the resharpened ones too). After some mishap with the Postal Service (took em over a week to deliver across 2 states!), I got them in, and DrillBitCity was very good about looking into the problem and offering to send them again. They're great! (as Tony the Tiger would say, lol)
They drill VERY quickly, make very clean holes (no burrs), and so far have held up much better than the previous (I'm guessing steel) bits. HIGHLY recommended for anyone drilling their own PCBs.
I just use a Dremel tool with these, but I actually had to turn the speed down compared to my previous bits because these things drill SO FAST! And, these are also much easier to load in dremel than the usual tiny bits since they have 1/8" base and a cool little collar that has the size marking.
I'd definitely recommend the bits and the company!
