What I Like

What I Don't Like

Design

The SKILSAW SPT77WML-01 circular saw has been thoughtfully designed to provide a sturdy and comfortable tool capable of withstanding demanding, heavy-duty use. 

I’ve found that its worm drive mechanism really packs a punch, giving you the kind of torque and power you need to slice through even the toughest materials. The design of these worm drive saws results in a pleasing balance.

The magnesium gear housing is not only light weight but also effective in dissipating heat, thereby contributing to the longevity of the saw’s internal components. 

As someone who’s done his fair share of extended sawing, I can’t stress enough how much that ergonomic grip does for your hands. You can go for hours without feeling like you’ve been wrestling a bear.

Additionally, the trigger is user-friendly and responsive, offering precise control over the saw’s speed. The saw’s footplate is composed of high-quality aluminum, providing a reliable and secure base while the saw is in use. 

Don’t sleep on the blade guard either; it’s made from some durable stuff that not only protects the blade but also keeps you safer during operation.

Skilsaw SPT77WML-01 Features

Overview of Specifications

Motor Power

Having tested this tool, I 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. 

I tried it in thick lumber and hardwoods, and it maintained consistent and smooth operation. Also, I 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 one of the common circular saw sizes 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. 

I used the tool for framing, decking, and cutting large pieces of lumber or sheets of plywood and had no issues.

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

Okay, so performance-wise, this thing is a beast. The 15-amp motor cranks out 5,300 RPM, so you’re not going to be waiting around for it to chew through material.

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.

Another aspect that caught my attention was the effortless blade-changing mechanism of the tool, which is further enhanced by the inclusion of a conveniently stored wrench. 

This added convenience not only saves me time but also ensures that the tool remains versatile and adaptable to various cutting tasks. 

Safety Features

This worm drive circular saw prioritizes safety with its various safety features to ensure protection during operation. 

I paid close attention to the metal blade guard; it covers the blade when you’re not cutting, and I noticed it smoothly retracts as soon as the blade makes contact with the wood. That’s a solid safeguard against accidental blade 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, you usually get a 24-tooth carbide blade, which is a champ at ripping through lumber and slicing through sheet goods. No complaints there.

Besides the blade, there’s 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 you have a window of 180 days from the date of purchase to return the tool and receive a full refund if you are dissatisfied 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, I would recommend a worm drive circular over the latter.

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.

FAQ

Does the Skilsaw SPT77WML-01 have an electric brake?

The tool does not have an electric brake, but it is unnecessary because the blade stops quickly in just a few seconds. This is actually beneficial because it can help you work more efficiently and productively without requiring a brake.

How do I change the blade of the Skilsaw SPT77WML-01?

To change the blade on the SKILSAW SPT77WML-01, rotate the blade stud in a clockwise direction to loosen it. Remove the stud and outer washer. 

Then, align the diamond-shaped opening of the new blade with the diamond-shaped shaft of the saw and insert it. Replace the washer and tighten the blade stud by rotating it counterclockwise. 

Will this saw work on a 220V power source?

This saw will not work on a 220V power source. The Skilsaw SPT77WML-01 is designed to operate on a standard 120V AC electrical outlet.
