I use my Dremel tool all the time for drilling my boards. I use a #70 drill bill. I don't even use a carbide bit and I have had no problems. Cheers. Harvey L. McRae, 838 McKenzie Rd., Kelowna, BC. V1X2B3, www.webs.com/harriscreekcentral

Is a dremel adequate for drilling pcbs using carbide drills? I know
it isn't good enough for pcb routing, but just for drilling?? If not,
what is a good, small, reasonably priced alternative?
