Worm Drive Design

SKILSAW SPT77WML-01 Worm Drive Design

The SKILSAW SPT77WML-01 Circular Saw is a worm drive model. First of all, why the name worm drive? Simply because there’s the worm wheel and worm screw. The latter meshes with the former, and this gear is pretty much like any standard spur gear. You get a higher torque and load capacity, no doubt about that.

The narrower profile, due to the motor centerline running parallel along the saw blade plane opens the door wide to better working even in limited or confined spaces. This worm drive circular saw is also furnished with larger gear teeth for a higher capacity of load-carry. Therefore, it’s the perfect power tool for heavy-duty applications.

Being a worm drive model, this SKILSAW SPT77WML offers plenty of other very useful benefits too. Such as its smoother and quieter operation along with a longer handle for more reach at the time of making cuts. For example, when working with sheet material requiring additional reach.

Worm drive is also equipped with a higher-capacity gear system. After all, it does feature bigger teeth that can handle tougher applications. Such as sheet metal, concrete, etc.

Another very practical advantage is the right-hand orientation since worm drive circular saws have the blade positioned toward the left. So right-handed users get a very clear sightline during cutting. Unlike sidewinder circular saws that are designed with the blade installed on the right side, which doesn’t really make sense because most users are NOT lefties.

And final benefits include less maintenance, longer shelf life, and the ability of this SKILSAW worm drive circular saw, because of its higher cutting power and torque, to complete the toughest of jobs (i.e. perfect for professional woodworkers).

Ergonomics

SKILSAW SPT77WML-01 Ergonomics

Once again, let me compare. In comparison to sidewinder circular saws, the worm drive version is certainly more manageable to use. Because sidewinder models feature a motor placed off-center. Along with a handle that’s positioned in such a way that you feel like you’re pushing down into, and not through, the work.

On the other hand, a worm drive circular saw like the current SKILSAW creation feels rugged and has heft. The gravity and weight of this thing carry the power tool, literally, right through that board like a knife slicing butter. You can use it for powering through wet lumber throughout the day without any complaints.

The back placement of the handle offers exceptional precision for the most effortlessly accurate cuts.

Even the super-lightweight magnesium design paves the way for very little to no user fatigue, thus perfect for long-hour or all-day use. And also reduced downtime!

Motor / Power Output

This home power tool has a Dual-Field motor. A 15-amp, powerful motor specifically crafted for preventing overheating during heavy-duty applications. The motor, since it’s a worm drive model, is installed at the back to enable quick power transfer to the blade. And this, no doubt, maximizes torque above all else.

Generally speaking, most worm drive circular saws offer a power rating of at least 4,000 RPM. This seems to be more than enough to complete both professional and DIY projects. Anything less than 4,000-4,500 RPM means a weak or underpowered motor, which is sure to give rise to a lot of performance problems along the way.

In that light, SKILSAW’s SPT77WML-01 is a capable machine when it comes to generating anywhere between 4,500 and 5,500 RPM. All thanks to its 15-amp Dual-Field motor.

Cutting Depth / Bevel Capacity

Knowing your circular saw’s cutting depth is very, very important indeed if working with specific materials. When the depth is too little, you cannot expect your saw to then cut through sheet material. Hence, it’s better when your power tool is able to cut at a slanted as well as 90-degree angle.

So you would be relieved to know that this circular saw, with its large 7-1/4 inch blade diameter, offers 2-3/8 inches as its maximum cutting capacity at 90 degrees. Along with positive stops at 0 degrees and 45 degrees.

Then you also get a depth adjustment level that’s Cut Ready. So you can make quick, easy adjustments for various ply sizes – 1/4, 1/2, 3/4, and 2x.

Moving on to beveling, a broad range is essential here too for cutting at an angle. The bevel capacity should be higher, no doubt about that either, for more versatility. And 53 degrees as the max. bevel capacity seems enough for most users for a broad range of cuts. And of course, pre-set bevel stops are a part of the mix for making your life easier.
