SKILSAW 15 Amp 10-1/4” Magnesium SAWSQUATCH Worm Drive Circular Saw Review

A 10" circular saw is a fantastic asset for any timber framer or carpenter. These saws give you an accurate 4" cut, fast, and clean cut. Every timber framer  (and even most dabblers)  should own a superb circular saw because they will make your life 20 times easier and less tedious.

Today, we’re going to learn all about the features and the quality of Skilsaw’s 10" Sawsquatch Circular Saw with worm drive motor.

The Blade

The main feature of this circular saw is the blade Skilsaw created for this particular model. This 40 tooth blade is 10 and 1/4 inches making you able to cut up to four times more material in one go than your average circular saw can. 

The similar SPT 70 WM-22 model uses a Diablo blade instead. A Diablo blade uses a non-stick aluminum alloy coating. The coating on these blades protects it from damage from heat and corrosion from weather or aging. These red blades are loved by most contractors when choosing their saw blades.

The Worm Drive

When a circular is called a “worm drive saw,” the name is referring to the design of the saw and the motor and gears used to get the blade moving.

In a worm drive circular saw’s case, the motor is placed behind the blade. This makes these circular saws longer and a narrower shape than most other circular saws.

This circular saw has a “worm screw.” This worm screw looks like a screw since it’s not round (like most gears) and it’s in a spiraled shape. Hence the name.

When this worm screw turns at 90 degrees, it hits a roundworm gear which, in turn, moves. This cuts down on the speed of the 40 toothed blades making it easier to handle while increasing the torque (or turning ability) for the power and strength of the saw’s blade.

With the motor located behind the blade, the motor is parallel to the 10 ¼-inch blade. This narrow design is fantastic for squeezing into smaller areas while maintaining the perfect cut of wood or other materials like different metals.

The Motor

This particular circular saw uses a 15-amp dual field motor to power this high-powered baby. The Sawsquatch circular saw’s motor was designed for saws and saws only.

This motor has the ability to cool itself down as it’s needed. You’ll never have to worry about an overheating motor which will increase the life of your Skilsaw Sawsquatch circular saw.

The Material

This circular saw by Skilsaw is made with magnesium instead of the standard aluminum used by most saws. The magnesium components in this saw make it both lightweight as well as heavy duty against any damage. It’s super durable upping the saw’s life even more.

The Extras of SawSquatch

The saw has an anti-snag lower guard. The anti-snag lower guard ensures that you have the ability to cut smaller pieces of wood without any complications. As its name suggests, it prevents snagging on the material you’re cutting.

It’s an electric corded saw. It has 120 volts and 1800 watts. The cord can stretch up to 8 feet in length giving you plenty of room to work with.

The saw weighs in at 16.5 pounds. It’s hefty but not as heavy as other circular saws on the market.


Skilsaw continues to be creative and innovative with their high-quality power tools. This model takes the cake for their newer models, outshining the other brand name circular saws out there. We highly recommend this worm drive circular saw Sawsquatch to all professionals and the more serious woodworking hobbyists.

The History of the Brand Skil and Skilsaw

Skilsaw started in the 1920s in the United States. In 1924, their first product and serious power tool was a portable worm drive circular saw that provided consistent single pass cuts time and again. In fact, they created the very first (ever) portable circular saw. The original saws were made with die-cast aluminum housing to last longer than other saws.

13 years later, in 1937, Skilsaw created their famous Skilsaw Model 77, another amazing portable circular saw. The model, with its durability, auxiliary handle, powerful Skilsaw blade, and internal cooler, is so awesome that there are those who continue to use it to this day.

During the past 4–5 years, Skilsaw has continued to step up their power tools game. They rebranded themselves by using the name Skil for DIY power tool hobbyists and using the brand name Skilsaw to sell more of the heavy-duty and professional power tools to contractors and construction businesses.

The Skil and Skilsaw brands continue to be dedicated to power tool users and their special consumers. They’ve dedicated 94 years of improving the quality of their products as well as integrating new ideas to the classic power tools we continue to use.

They’ve also come out with a heavy-duty saw for slicing through fiber cement, the very first worm drive saw to slice through concrete, and even a worm drive table saw!

As of 2016, Skil and Skilsaw are owned by the company Chervon and is marching onward.
