Cheaper alternative...........
Don't know about the Dremel but my Chinese knock off (cost $20-25) has no slack and runs at 8000 - 2500rpm, continuesly variable, no load. Most of the time I run it at about 3/4 of max, in order to keep the noise down. Have never broke a drill bit.philba said:For drilling pcbs, you really want a very high speed drill. well outside the price ranges you guys are talking. I used to use a delta drill press with a cross sliding vise. it was ok but I broke a fair number of carbide bits. this will happen with most of the lower speed drills. the Dremel has the advantage that it runs at high speed but has huge slop.
I use a Sherline mill now for drilling and haven't broken a single bit yet. it spins at 30K and is pretty accurate. I'll convert it to cnc some day for even better results. I bought it for a song at an auction - around $150.
