How do electric drills work that make the “clack clack clack” noise when driving in a particularly stubborn screw?

If it’s a drill (with a chuck to put bits in) it’s because of a clutch that prevents you stripping screws or burning out drillbits (usually you can set the amount of torque you want).
If it’s an impact driver (just a bit to drive screws) it’s because of a hammer in the motor that is meant to drive screws without stripping them.
