Why do you need a worm drive saw?

In a worm drive saw, the motor transfers the power to the blade through a threaded worm drive down the shaft which turns the pair of gears oriented at 90-degree angle from each other. This causes the saw to spin in reduced rotational speed but with better torque. This torque provides the saw with enough cutting power.
