One Power Devil and one McKeller.</p>
<p>The Power Devil is the usual bottom-rung battery drill, though looks like it’s been fitted with a replacement chuck.</p>

<p>I opened up the battery pack, and it was pretty much what I expected.</p>

<p>Mostly empty.</p>
<p>The McKeller on the other hand was much nicer and more powerful. However neither drill had a charger unit, so they’ve both been stripped down to motor and gearbox. I’m thinking they could be good for making a reasonably powerful robot arm.</p>
<p>The chucks on all of them attach with a 24tpi UNF thread. I might have to belt-gear them down, but then again PWM control would probably be fine and simpler to attach.</p>

The fuses are still good, and the breakers haven’t tripped.</p>
<p>I think the motor just blew.</p>
<p>This is troublesome.</p>
