I haven't looked at every single speed controller on GiantCod but from what I can see browsing through them, they're all designed for brushless motors. You'd need one designed for DC brushed motors to be able to control drill motors.

If it's the same type of blue boat controllers that were quite popular a few years ago, then you're probably looking for something like this:

There are no specs on this particular eBay item but if you search for '50a esc' you'll find a few of them up for sale. Generally they are rated at 50A forward, 20A reverse and have an operating range of 6-12V, although some people have managed to run them at 14.4V.

If they are the same ones I used (and the look to be) then yes they will run drill motors. For example:

You will be limited to 12V max operating voltage (maybe 14.4V but I never used them at that voltage so can't guarantee anything) so if you later fit a weapon that requires, say, 18V to run, you will then have to look at some way of getting 12V out of your 18V battery supply.

You may be better off spending a little more and getting a pair of Electronize controllers that go up to 24V; that gives you more flexibility further down the line and will also provide smoother control than the blue speed controllers. Depends on your budget though.
