Cordless Micro Drills

[CLovehitch]

Is anyone using the WowStick Micro cordless drill?

Any suggestions for good quality Micro drill?

Thanks, Nick

I have had a General Tool cordless screwdriver with a chuck attachment. 

It works as a reamer, but the RPM are not all that they could be, nor the power.

 

I suspect any battery operated mini drill might not perform as well as desired.

 

A small DC motor with narrow gauge wiring to a selectable power supply ( MPJA ~$25) -more power - small enough wire not matter vs wireless.

AliExpress  features small motors - some with a larger Jacobs chuck - and some with a #60 or smaller keyless chuck.

 

Anything with a fixed DC output transformer will probably under perform.

As I understand it, a DC motor will tolerate higher voltage or amps - maybe have a premature death - but they respond poorly to an under the rating power supply?

If you are asking about micro-motor drill motors for drilling holes with small bits, read this thread. It starts out with a discussion about drill bits, but drifts into a discussion about drill motors generally.

Along with what Bob is saying, I don't see that being much more useful than a pin vise.  It is going to stall very easily and the tool selection is very limited compared to devices with a 1/8 collet sharing the Dremel type tools.

 

While not cordless, I have found this to be very useful for light work.  It weighs in at 6.8 oz, so is very easy to use.

It also takes the Dremel keyless chuck eliminating the need to change collets for the smallest drill bits on up to 1/8  for all Dremel type accessories.

This drill appears to be aimed at the craft market; jewelry, Knick knacks, etc. where things don’t need to be measured.  The tool, therefore, is not fitted with a  chuck to accept different sized drill bits.  Instead the drill uses proprietary bits all with the same sized shank to fit into a socket.  This would seriously limit is usefulness and lifetime.  Which will fail first, the drill or the proprietary bits?

I should have searched harder.  I bought a regular dremmel and I find it way to powerful.  This thing would be perfect for me...

  The 'Chicago ' variable speed flex-shaft drill (sold at Harbor Freight) I've enjoyed BOTH power and lower speeds (modulated by a foot control - like my 'old school' sewing machine).  I do have to use an Enco mini pin chuck (has three small collet sizes) to use 'wire drills' for the best results.  Yeah, there is that flex shaft attached to the motor that hangs from a provided wall hook.  'Same would be true for a old-style dental drill ... my brother got that from my dad's estate 'cause he was there first.

HF used to all but give away a small hand drill with a single volt transformer.  Totally useless as sold - too weak.  

When plugged into a variable power supply and the voltage cranked up - it works.

Speed is a poor substitute for torque.
