What Is a Worm Drive Saw
A worm drive saw is a type of circular saw where the motor’s centerline is parallel to the plane of the saw blade.
This design allows for a narrow profile, making it easier to use in tight spaces.
It also has a longer distance between the handle and the blade, increasing reach for cutting, especially with sheet goods.
The larger gear teeth in a worm drive saw provide higher load-carrying capacity and more power, but also add weight.
These saws typically weigh around 13-14 lbs and cost about $150 to $200 for professional-grade models.
Did You Know?
1. Worm drive saws are named after their unique gear system, which features a worm gear that drives a worm wheel, enabling the saw to deliver more torque than other types of saws.

Enhanced Power And Load-Carrying Capacity
One of the reasons why professionals choose worm drive saws is their enhanced power and load-carrying capacity. Compared to direct drive circular saws, worm drive saws feature larger gear teeth, which contribute to their increased load-carrying capabilities. This means that worm drive saws can handle heavier workloads and provide more power to cut through tough materials effortlessly.
While the added power is beneficial for tackling demanding tasks, it’s important to note that it comes at the cost of increased weight. The average weight of a worm drive saw is around 13-14 lbs, which is slightly heavier compared to other types of circular saws. However, this trade-off is justified by the worm drive saw’s ability to deliver superior cutting performance, making it a top choice for professionals who prioritize power and durability.
