I’m totally a newby here so I apologize beforehand.
I’m trying to make an electric screw-driver, well actually 4 electric screw-drivers sitting next to each other so I am looking for the most miniaturized package (for the motor and any gears necessary) I think the minimum torque required would be ~100-150 in-oz.
I appreciate all the advice/help on choosing the best motors while keeping the project budget friendly…

Consider something like this (budget friendly and within the specs):

If size is important, you’ll notice that in order to get the torque you need, the gearing has to be quite high, making the output rpm quite low.
If you need something which is both high rpm and high torque, you’ll need a physically larger motor.
Cool, thank you for the quick response!! Will I be able to control the rotational speed of these motors using an Arduino?
Yes, but you’ll need a DC motor controller between the Arduino and the motor since an Arduino cannot directly provide the necessary current.
