How does a cordless drill trigger work?
The drill’s mechanism is actually quite simple: A trigger switch activates an electric motor, which in turn drives a rotating chuck. Numerous accessories can fit into in the chuck, allowing the drill to bore holes, drive screws, and sand, polish, and grind a wide variety of materials.

What is the common cause of breakdown of electric drill?
Possible Reasons for a Defective Power Drill Claim Unsafe design/design defects. Lack of proper safety guards. Improper warning provided. Manufacturing flaws.
Can you fix a burnt out electric motor?
If an electric motor operates at too high a voltage, excess current flowing through the windings can cause them to become hot and burn out. While it is normally not practical to repair small, direct current (DC) motors that have burned out, other motors can be repaired by rewinding.
Why do drills burn out?
If you put too much pressure on an electric drill while you’re drilling, or if your drill bit is blunt, the drill can overheat and may burn out. So when you’re drilling in masonry or concrete it’s a good idea to withdraw the drill regularly. This allows dust to escape and gives the drill a chance to cool down.
