Good afternoon, and welcome to the Technical section in Just Answer, an independent paid question and answer platform that matches customers' questions to experts in various skills. My name is ***** ***** I'll be happy to help you today.

I'm sorry to hear of your power tool problem.

A damaged flex, or loose connection in the plug, can make it appear as though there is power. Note that a volt stick won't give you the full answer, so have you measured 240 volts at the drill?

Customer: replied 20 days ago.
110 volts
Expert:  Tim JA replied 19 days ago.

OK.  Are you using a transformer?

With others tools

OK. So if there's 110V at the drill terminals, and the switch isn't faulty, and the brushes and springs are in good condition, then it seems likely that there's a breakdown in the windings in the motor.  Can you measure the resistance of the windings?

How do I measure the resistance

To diagnose this further you really need a multimeter. For a cheap but good one click here.
