12 to 24 volt battery operated tools do not "broadcast" very far - either from the brushes or the PWM controllers. Cheap Chinese line operated power tools are another story altogether.

Actually this brings up a good point...do manufacturers of cordless tools worry about RF interference? TMT

Correct..if the tool's balance needs to change, one can do a number of things to help. The longer one uses it at one time, the more important the balance is. Like a good target rifle, the better the balance the better performance. TMT

That would depend on the control circuitry and motor combination used by the tool, and the voltage of the substitute battery used. There can be considerable di/dt, normally handled by the local battery's placement. Stick the battery at the end of a cable, you'll get more than just DC cable losses - there will be voltage spikes at the load, voltage ripple on the controller supply, and rdiation from the interconnection. I'm not worried. It's not my tool, but you don't paint just one side of a fence. It IS becoming increasingly difficult to get clean and stable FM broadcast reception - never mind AM - particularly from smaller or distant stations. I expect there are similar problems over the rest of the spectrum - with effects not so easily identifiable by the victim. The perpetrator is, inevitably, ignorant of them. RL

RADIATE? If you are worried about AM radio interference throw a ferrite torroid on the cord at the rool end. If your worried about something else, don't be - because it is NOT a problem.

You might want to consider adding snubbers or clamps to the switch and harness, at the motor. The harness may also radiate. RL
