You might be able to bet by with a battery charger and a filter capacitor.

There used to be a TON of Saturn windshield wiper motors on the surplus market. My students used two of them to drive a 50lb nuclear waste recovery robot they built for a design contest. These motors cost less than $20, had three speeds built in, and their robot had power to spare, think monster truck crazy power.

The Saturn (made by Trico) units seem to all be gone, but this place has crazy deals on the stuff:

Your diodes/rectifier will need to handle the current of the drill or motor. And it will not hurt to go larger. But no signal diodes. The inductive motor will require a regulator as long as T1 (not labeled) is close to you battery voltage.
