But if you see more sparks than usual AND the drill is smoking, your brushes are probably shot. I own a corded drill and two cordless drill, and I break out the corded drill anytime I need a lot of power to drill a hole. If you were trying to drive or remove a screw and your drill started overheating, this is the tool you want.
Note: If you driving the screw in, you drilled a pilot hole, right? You might also want to try a larger pilot hole as well before splurging on a new tool. The easiest way to tell if the battery is the problem is to stick it on another tool. Still smells funny? The drill casing is made of plastic, and as we all know, plastic melts. Check the below reasons for overheating the drill. Apply More Pressure Covering the Ventilation Holes Insufficient Torque Electrical Short Mechanical Problem Old Brushes Continous Working No Lubricants Wrong Drill Bit Angle.
You can check in detail about drill overheating on Why is My Drill Overheating? You can do it yourself by using electrical contact cleaner and compressed air. If you can remove the inner dirt material such as dust between the commutator copper parts, do it. Those will cause the spark and smoke. Smoking is a result of the friction of the commutator and brushes, as well as for many reasons that I have mentioned above, so if you need to avoid smoking and overheating, do regular maintenance.
I have my own workshop and I spend my free time with so many projects. Or, maybe someone made the drill work harder than it was engineered to operate. You could have a bearing seized within the drill. Numerous other issues can go wrong with a motor.
Tinkering with the motor is not always straight forward. It is very uncommon for modern batteries to short out. Most will automatically shut down before becoming dangerous. However, if your battery does develop a short circuit , you could see some smoking from your drill. The best thing to do in this situation is to keep the drill away from flammable objects. A new battery might fix the problem.
However, these sparks should not be shooting out of the drill. It is possible to clean out this area of your drill and repair the sparking. Just like a car needs regular tires and oil changes, your cordless drill should be cared for regularly. If your drill begins to run a bit rough, it could use some oil. Oil does several things for your drill. First, the oil will help your drill run smoothly. Second, the oil will cut down on heat. The less heat you have, the less sparking you should have to deal with.

I'd say the drill is gonna die and it is likely a warranty-covered death. This is specific drill is professional, so it almost surely has overload protection that should limit the current when there's serious overload. I guess this protection simply didn't kick in and this is a warranty-covered incident. I would definitely send it in to Milwaukee under warranty, telling them the drill overheated and smoked when the drill failed to stop on an overload.
