Nope, not at all. I'm using a MasterCraft drill press model # 55-5917-0.
It looks a lot like this unit:
http://www.canadiantire.ca/assortments/product_detail.jsp?PRODUCT%3C%3Eprd_i
d=845524441897707

It has speeds of 570, 900, 1390, 2090 and 3050 with a built-in lamp, very
useful. It is set at 3050 RPM right now and I've done many circuit boards
with it. The shaft rotates true and doesn't break any tiny carbide bits.


I use a Minicraft drill (MB1012) and stand at max. speed (18,000 rpm) for
drilling PCBs, with tungsten carbide bits. There is a bit of slop in the
bearings, but I don't break too many bits.
