small good quality driver??

[MtLuke]

I'm looking for a small driver for a Twin-Dinotte style build I'm doing. The driver needs to be smaller than 3/4" and of good quality. I would also like it to be able to handle up to about 18 volts. I know Sandwich Shoppe has a few, but the voltage is too low, I don't want to alter any of the battery packs I already have.
Thanks, Eric S

You could see if the measurements from taskled.com CCxW driver will work.

It's not round but it may fit lengthwise.
