Motor Power
Having tested this tool, we can confirm that its motor produces remarkable power. Unlike other worm drive saws, this is powered with a 15-amp capacity that provides enough torque to cut through challenging materials effortlessly.
Our woodworkers tried it in thick lumber and hardwoods, and it maintained consistent and smooth operation. Also, we found that it has dual copper windings technology which reduces its temperature.
Blade Size
This circular saw features a 7-1/4 inch blade size, which is a common size for circular saws used in woodworking applications.
The blade is large enough to make deep cuts through thick materials, which is useful when working with larger pieces of wood or when making rip cuts.
The 7-1/4 inch blade size is also convenient because it is a standard size for most circular saws that are widely available, making it easy to find replacement blades when needed.
Cutting Capacity
This tool has a 90-degree cutting capacity of 2-3/8 inches, which means it can make a cutting depth up to 2-3/8 inches deep at a 90-degree angle to the workpiece.
During our testing, we used the tool for framing, decking, and cutting large pieces of lumber or sheets of plywood and found that it was well-suited for these tasks regarding cutting capacity.
It also has a bevel capacity of 53 degrees, which allows for angled cuts up to 1-3/4 inches deep. This bevel-cut system makes it versatile for cutting bevels, compound miters, and other angled cuts commonly used in woodworking projects.
Performance and Ease of Use
We were impressed by its exceptional performance and user-friendly features. Its 15-amp motor with 5,300 RPM offers speedy and efficient cutting through various materials.
Despite its impressive power, the saw’s lightweight construction, weighing only 11.5 pounds, makes it effortless to handle and operate, even over extended periods. The tool’s ergonomic design, coupled with a soft hand grip, further adds comfort and control.
We were also impressed by how changing blades is effortless, as it features a conveniently located wrench stored on the tool.
Safety Features
This tool prioritizes safety with its various safety features to ensure protection during operation.
One of the most crucial features is the blade guard, which is made of metal and covers the blade when unused. During our test, it automatically retracts as the blade contacts the workpiece to prevent accidental contact.
Another important safety feature is the anti-snag lower guard [1], which prevents blade binding in the workpiece and helps reduce the risk of kickback. The lower guard’s maneuverability also aids in improving the saw’s overall safety and accuracy.
Other Items in the Box
In addition to the circular saw itself, the box typically includes a 24-tooth carbide blade that is specially designed to handle ripping through lumber to cutting through sheet goods.
In addition to the blade, we also found a multi-function wrench that makes it easy to change out the blade when needed.
Warranty Period
It comes with a 180-day money-back guarantee warranty. This means that you have 180 days from the date of purchase to return the tool for a full refund if you are not satisfied with its performance.
Top Alternatives for the Skilsaw SPT77WML-01
If you’re looking for a solution to the vibration problem, your only option is to go for the Makita 5377MG, which boasts well-designed, rubberized handles.

Though both machines are tough competitors, the SKILSAW SPT77WML is more suited for framing work, even if it’s a bit cheaper than the Makita unit.
Customer Experience and Reviews
This circular saw has received overwhelmingly positive reviews from customers who have used the tool for various cutting tasks. Many customers praise the saw for its power, durability, and ease of use, as well as the light weight design.
Of course, as with any tool, there are some negative reviews as well. Some customers find the saw to be too loud or have too much vibration.
Should I Opt for a Worm Drive or Sidewinder Circular Saw?
Ultimately, the decision between worm drive circular saws or a sidewinder circular saw depends on your individual needs and preferences. If you’re a professional contractor who needs a powerful saw for heavy-duty tasks, a worm drive circular saw may be the best choice.
If you’re a DIYer or hobbyist who needs versatile circular saws for various projects, a sidewinder saw may be a better fit. It’s also worth considering renting both types of saws to try them out before deciding.
