Take the two speed Dremel,to an electric components shop they can cobble together a speed dial (like controller for model trains) to lower the rotations to a manageable level.

Unfortunately both the cost and space rule out the drill press, I am in a 1bd apt. I do have a cordless dremel but it unfortunately spins way to fast for what I need to do. I need 4-500 rpm, the slowest it goes (only two settings) is 5000rpm. So I needed to find a different route than dremel. But thank you again for all your help. It is really appreciated!

I tried to do some more looking and stumbled upon a Jewelry site called Fire Mountain Gems. They had a Micro Adapter Pin Chuck Set / Part Number H20-4828TL. It has a 3/32 (2.38mm) shank and is used for #61-80 bits. They are less than $3 US. I figure that should fit the Tamiya drill as it has a collet for 2 to 3mm bits. Am I right or way off????

Dremel makes several collets to fit. By the way, have you thought of a Dremel drill press or stand if you have difficulty holding your drill? Again, Try looking at the Micro-Mark catalog or Dremel's website. I have a Dremel drill Press/stand, and use it to drill with one hand or no hands, it holds the drill at any angle, so you can bring the item to the bit.

Hello Everyone,
Due to some health issue with my hands, I am looking at a Tamiya Handy Drill to use. I would like to use it for my #61 to #80 drill bits, the real small ones. Is this possible? If so, HOW? I can't for the life of me figure it out and what I would need. I would appreciate hearing from anyone.

Best Wishes,

Walter




Have you looked in the Micro-Mark catalog? besides carrying popular Dremel tools and bits, They also have several miniature powered drills and bits. I recently purchased a slow speed battery powered screwdriver from them, along with an adjustable chuck that converts it into a drill. The Drill cost $34.95, the chuck was about $20 (later, I found the same screw-driver/drill in the tool section at Lowes for $19.95--but without the chuck). With the add on chuck It's a very good slow speed drill, and is very handy in that it has a forward and reverse direction switch. With the chuck, it takes drill bits as large as 1/4 inch, and reduces down to basically nothing-- holding the smallest of bits. The only drawback I've found is it requires constant pressure on the switch to operate--but you get used to that. It offers a lot of slow speed drilling control> I have an older lithium battery Dremel I can reduce down to about 2000 RPM, but even at that slow speed, I sometimes have difficulty with control. This drill solves that problem.

Thank you all for the ideas. Unfortunately I do not have the ability to create what I need. I really like the idea of the mini chuck, would work fine but it is .175 mm to thick. The Tamiya drill collet goes up to 3mm, the 1/8 in chuck isn 3.175. Also the dremel idea is good but I have no way of making my own insert, tape would just wear out to quick. Wish I knew someone who could possibly modify the 1/8 chuck to fit, that would be ideal. I just can't grasp things for a decent period of time, cramps and loss of control plague me.

Open to all and any ideas, please keep them coming. Something must work for me.

I think the vice-grips(Edit: the correct word is collet) that holds the drill bits are too large for most of the drills in the range #61 to #80, #61 and maybe a few more might fit but the smaller ones will just drop out (see link in Ryans post below: #66 is the smallest drill that will stay in place).

If you could find small drills with larger shanks, sort of one size shank for all sizes of drill bits ....
Another possibility is to find or make vice grips for smaller drill bits ...
/ Robin

Edit:
Two examples, there are probably others
Small drills with larger shanks:
https://minitaps.com/drill-bits-50mm-to-2-50mm/drill-bit-99mm-61/

or a Micro drill chuck:

on the other hand: I don't know if I would trust this Handy Drill ....
