Hey Doc...The problem I've always encountered with using a Dremel as a free-hand drill is that, even with the variable speed models, the RPM is too high for accurate control. I went out and found this, which works really well:

Yep... Agreed.@Hobbit99 Whatever the tool, Dremel, Proxxon or others I think a 3 jaws chuck will never be as accurate as collets. Especially for small diameter drills
Here is mine, running at pretty low speed with a #69 drill chucked into it. Not much wobble. Your mileage may vary!

I have the same Dremel handpiece, it is really compact, has variable speed and doesn't wobble. I mean acceptable. I drill holes for hull treenails with 0.4mm drill bit.The rpm is 5000 to 22000 works real good is quiet too
Another way to reduce the 'wobble' effect, is to leave the drilling part of a drill bit as short as possible, just long enough to penetrate the part.Watch, I'll buy one and it will wobble around like a drunk man on a skateboard.!!
Thanks Janos...My choice is the Micromotor, which I am using for drillbits (no wobble) as well as for carving. Speeds from 0 to 35000 and absolutely concentric. Small dia body, smooth running with speed control foot pedal this is the perfect tool for modelling.

Nice selection.!!For heavy duty work, cutting, grinding, my Fordom tool. Corded, with a variable speed foot control, cable driven handpiece, collet, great for wood carving.
For lighter duty work, my cordless Dremel. 5 speeds, but most quite fast. Compact, fits my hand well. I use it a lot.
For drilling, I use these two cheapies. Both were listed as screwdrivers. The red one has two speeds, the grey one one very slow speed. I find the speeds to be very good for control when drilling. Not real fast, but much faster than a ball pin vice.
Lastly, the pin vices. I like the ball handle ones the best as they seem to fit my hand well. The black one, third from the right I have in 4 sizes - came in a set. The last one on the right is a "push" drill. Kinda works like the old "Stanley Yankee" screwdriver.
Slow? I guess. Accurate and controllable? The best for me.
I have several 3 jaw chucks that can be held in a 1/8" collet and I use them for grinding and cutting bits mostly, taking them off and using the collets in them for drilling.

dont knock it till ya try itYep... Agreed.
