Sidewinder circular saw: This is one of the most common types of circular saw used by the majority. The motor is attached to the left side of the blade to ensure that the saw is portable and compact.

Usually, sidewinder circular saws are backed by a lithium-ion battery.

Worm drive circular saw: One of the alternatives to a sidewinder saw is the worm drive circular saw. Unlike a sidewinder saw, the motor is placed at the back of the blade. This somehow reduces the speed, but the torque is much higher. The power is relatively high and the saw is quite durable compared to the other saw.

Hypoid circular saw: These saws fall right in the middle of worm drive circular saw and sidewinder circular saw. Just like worm drive saws, the motor is placed behind the blades. Hypoid saws use non-intersecting serrated gears to convey power to the blades. The best part is the engines do not have to be oiled. The gears certainly allow the saw to work in silence and make less noise than the worm drive saw.

Abrasive circular saw: Different types of circular saws are used for different purposes. The abrasive circular saw is used for cutting firmer and sturdy materials. These saws are also known as the chop saw, as the teeth of the blades quickly go through all the challenging elements. One can use it by hand or fix it over the table.

Biscuit jointer: This is one of the unique circular saw types used to join material parts. When the blades create a tear on the material, a remaining wood called the biscuit is attached between the sides.
