Updated July 2026 — full head-to-head comparison.

Overview of the SKIL 20V Brushless Circular Saw Kit and SKILSAW Worm Drive Circular Saw

The SKIL 20V Brushless Circular Saw Kit is priced at $79.00, making it about 72% cheaper than the SKILSAW SPT70WM-01, which retails for $284.80. This significant price difference highlights that the SKIL 20V saw is designed for casual users or DIY projects, while the SKILSAW Worm Drive is aimed at professionals who require more power and capability.

The SKIL 20V Brushless Circular Saw Kit includes a 2.0Ah battery and charger, making it a complete, ready-to-use package for wood cutting. In contrast, the SKILSAW Worm Drive Circular Saw is specifically engineered for heavy-duty tasks, particularly for cutting through larger materials like 4x lumber in one pass.

Power and Performance

The SKILSAW Worm Drive Circular Saw is a powerhouse with a 15 Amp Dual-Field motor that delivers relentless power and durability. This saw is designed to keep the motor cooler, enhancing performance during prolonged use. In comparison, the SKIL 20V Brushless Circular Saw features a brushless motor that delivers up to 5,500 RPM, allowing for efficient cutting of 105 times through 2x4 pine on a single charge.

When considering performance, the SKILSAW's ability to cut 4x material cleanly in one pass stands out, while the SKIL 20V saw is more suited for lighter, everyday tasks. This makes the SKILSAW better for professional applications, while the SKIL 20V is ideal for DIY enthusiasts looking for a compact solution.

Design and Ergonomics

The SKIL 20V Brushless Circular Saw is compact and features an ergonomic design that enhances visibility with its blade-left orientation. This design can be particularly beneficial for users who prioritize precision in their cuts. Additionally, it includes innovative features such as an LED shadow line that improves visibility of the cut line.

On the other hand, the SKILSAW Worm Drive Circular Saw boasts a magnesium construction, which not only contributes to its legendary durability but also keeps the saw lightweight for its size. However, it lacks some of the compact features that make the SKIL 20V more user-friendly for smaller projects. Thus, while the SKIL 20V is designed for ease of use and visibility, the SKILSAW focuses on durability and power, catering to different user needs.

Safety Features

Safety is paramount when using power tools, and both saws incorporate features designed to enhance user safety. The SKIL 20V Brushless Circular Saw includes an electric brake that stops the blade quickly, providing an added layer of safety between cuts. This feature is particularly useful for reducing accidents during operation.

Conversely, the SKILSAW Worm Drive Circular Saw features an anti-snag lower guard, ensuring smooth operation even with small cut-off pieces. While both saws are designed with safety in mind, the SKIL 20V's quick-stop electric brake may appeal more to novice users, while the SKILSAW's design caters to professionals who may encounter more challenging cutting scenarios.

Battery Life and Runtime

One of the standout features of the SKIL 20V Brushless Circular Saw is its industry-leading PWR CORE 20 lithium battery technology. This technology allows the battery to last 25% longer per charge and provides double the battery life compared to conventional batteries. This longer runtime is a significant advantage for users who need to complete multiple cuts without frequent recharging.

In contrast, the SKILSAW Worm Drive Circular Saw does not rely on battery performance, as it is a corded model. This means that while the SKIL 20V offers flexibility and mobility, the SKILSAW provides the advantage of consistent power without worrying about battery life. Users must choose based on whether they prefer the convenience of cordless operation or the continuous power of a corded tool.

Ideal User

The SKIL 20V Brushless Circular Saw Kit is best suited for DIY enthusiasts, homeowners, or those who need a reliable tool for everyday woodworking projects. Its compact design, ease of use, and included battery and charger make it an excellent choice for those who may not require heavy-duty cutting capabilities.

Conversely, the SKILSAW Worm Drive Circular Saw is tailored for professionals or serious woodworkers who frequently handle larger materials and need a powerful saw that can make clean cuts efficiently. Its robust design and powerful motor make it ideal for job sites and demanding applications.

Price Comparison

With the SKIL 20V Brushless Circular Saw priced at $79.00 and the SKILSAW Worm Drive Circular Saw at $284.80, there's a clear financial distinction between the two products. The SKIL 20V is approximately 72% less expensive than its counterpart, making it an attractive option for budget-conscious consumers. However, the higher price of the SKILSAW reflects its advanced features and capabilities aimed at professional users.

This price difference suggests that users should consider their specific needs and how often they intend to use the saw. For occasional use, the SKIL 20V may be the better choice, while frequent, heavy-duty users will likely find the investment in the SKILSAW worth it.

Which should you buy?

Choosing between the SKIL 20V Brushless Circular Saw Kit and the SKILSAW Worm Drive Circular Saw ultimately boils down to your specific needs and budget. If you are a casual user looking for a lightweight, easy-to-handle saw for wood cutting, the SKIL 20V at $79.00 is an excellent option. However, if you require a powerful tool capable of handling larger projects and demanding materials, the SKILSAW at $284.80 will serve you better in the long run. Each saw has its strengths, so carefully assess your requirements before making a decision.
