I am looking for a miniature drill of a type that used to be widely available, but now seems hard to find. They are smaller than Dremels, and ran on 12-18 volts DC (with an AC adaptor). They would run at about 15,000 to 24,000 rpm.

A good example is the Bosch MBM40.

Anyone know where to get such things?
 
Your talking about a 1/4 inch drill... used almost exlusively in aircraft repair/manufacture!

The little air drills are real cool, super high RPM and a real fine hole. The problem? Expensive to buy... and most people need more power!

I havent seen a small electric drill in a long time. But I do know what your talking about. A handle with maybe 4 inches of stuff before the chuck.
 
First of all, thanks for all the replies.

This may be more information than anyone wanted to know, but this drill will be used for experimental surgery. Smaller is better, and because of motility issues,it must be electrical.
 
Surgery as in medical?

I dont think any of the above would work in a medical environment just because of the sanitation problems! :eek:
 
you looking for something like this:

Happy Spelunking!
 
Thanks, but I have tried those (and similar options). And I have taken care of the sanitation issue. It is surgery, as in medical.

The requirements are lightness of weight, small diameter, running on electricity (not compressed gas) and ability to accomodate 1/4 - 2 mm
burr heads.
 
Most of the drills that I sue are dental drills, but I need somehting a little more specialized.

And home trepanning is NOT an option. :D
hmm, maybe we need an icon for that.

I am a biomedical researcher, and need this to go through very delicate skull bone. Under normal circumstances, the pressure-powered dental drill is fine, but I now need something more portable. It also has to hava a good "feel", so I can tell what I am doing, if that makes sense.

Now, you would think that some of my colleagues would be able to help, but I have made the rounds, and not too many people are doing this kind of work--it could just be that I am "cutting edge", if you'll pardon the expression. So, I turn to the biggest community of gearheads that I know.

Quite seriously, the people that post on Bladeforums have about the greatest variety of experience that I know of. That is the reason I posted this request.
 
I know what you are looking for.I have about six of them. They are used in dental labs.I make my living carving ivory and fossilized bone and use a micromotor every day.They are not cheap.they cost from $250 to $1000.
I have four Osada , http://www.osadausa.com/ ,
and they are top quality.I have bought all of mine used.I have two being rebuilt and it will cost $100 for each of them.Do a eBay search on ,lab handpice , and you will find some.
 
Um, were the M130 and 150 minicraft drills still too big? Would a little Fordam flex-shaft tool work? Jewlers and carvers seem to favor them.
