The Ultimate Circular Saw Buying Guide (2026)
Circular saws are essential for straight, fast and accurate cutting in wood, steel, masonry and ceramic. They can also be configured to make reliable and consistent bevel cuts – something that is usually time-consuming and tricky to do by hand.
If you’re a DIYer or a professional, a good circular saw in your arsenal can make light work of just about anything you undertake, saving you time and frustration.
A good quality circular saw will last you for many years, and you will wonder how you managed without one, so it is worth taking some time to get the right one. By the end of this article, you should have all the information you need to decide which circular saw is best for you.
Basic Guide to Circular Saws
Circular saws are the go-to tool for making speedy, accurate straight cuts through wood, steel, masonry, and ceramic when paired with the right blade. The cutting action is performed by a toothed or abrasive blade, driven on a rotational axis by a motor. A Cordless circular saw is powered via lithium-ion batteries, and as you might have summarised, a corded circular saw draws its power from the mains.
Key Features to Consider
Use Branded Tools
When investing in a circular saw, saws from reputable brands like DeWalt, Milwaukee or Makita are always a safe bet. Branded tools are always the better choice due to their superior quality, reliability, and comprehensive support. Leading brands implement strict quality control measures to ensure their products meet high standards of performance and durability. This reliability is enhanced by warranties and access to customer service, providing users with peace of mind and assistance when needed. Moreover, branded tools often offer compatibility with various accessories and feature innovative designs, which increases their versatility and efficiency. While they may have a higher upfront cost, their long-term value, durability, and ease of maintenance make them indispensable for both professionals and DIY enthusiasts.
Check the No-load speed
No-load speed refers to how fast the blade rotates when it is not cutting through any material. This speed is typically measured in revolutions per minute (RPM). No-load speed is a good indicator of cutting power; generally, a higher RPM suggests greater cutting power. However, it’s important to keep in mind that the blade’s diameter also affects its rotation speed. In simple terms, smaller blades tend to spin faster, while larger blades rotate more slowly. For more demanding cutting tasks, it’s advisable to choose a tool with a higher no-load speed. This DeWalt circular saw spins at an impressive 5800 rpm and will handle most cutting tasks you decide to throw at it.
Voltage
A higher-voltage circular saw typically offers more power and torque, making it easier to cut through tougher materials. However, these saws tend to be heavier because they have larger motors designed to utilise the higher voltage from the power source. If weight is a concern and you don’t require the additional power, it’s best to choose a lower-voltage circular saw.
Cutting Capacity
Cutting capacity refers to the maximum depth a saw can cut. Generally, a larger blade will have a greater cutting capacity. If you frequently work with thicker materials or need to make multiple cuts at once, it’s advisable to choose a saw with a higher cutting capacity, such as the Makita DSS611Z 18V LXT Cordless 165mm Circular Saw. However, if you primarily work with thinner materials, cutting capacity may not be as critical.
Cordless Circular Saw vs. Corded Electric Saw
The type of application for which you primarily use your circular saw will determine the power source you choose. Corded circular saws offer the main advantage of a constant power supply, making them a good option for projects that require frequent, power-intensive cuts in thick, hard materials, especially when you have access to a mains outlet. In contrast, a cordless circular saw prioritises portability over constant power, allowing you to work anywhere the job demands. This is a significant advantage for tradespeople and contractors. Additionally, the absence of a power cord reduces the risk of on-site tripping hazards.
Types of Circular Saws
Sidewinder and worm-drive circular saws
The most common type of circular saw is likely what most people envision when they think of one. A “sidewinder” is a type of saw where the motor is mounted directly next to the blade, driving it directly. In contrast, a “worm drive” saw has the motor positioned behind the blade, driving it through a gear mechanism, which provides greater torque. These portable saws require minimal maintenance and are excellent for cutting wood.
Mitre saws
A mitre saw is a circular saw mounted on a swinging radial arm, allowing the operator to bring the cutting blade down onto the material precisely. This design makes mitre saws ideal for accurate angled cuts, particularly in framing, moulding, and trim work. Their fixed nature enhances safety, making it easier for less experienced users to achieve consistent results while reducing the risk of errors. However, mitre saws are usually more expensive than hand-held circular saws, but their accuracy, ease of use, and added safety make them a valuable investment.
Table saws
A table saw features a fixed cutting disk mounted on a sturdy table. Unlike handheld saws, where the tool moves across the material, the material is pushed toward and across the blade with a table saw. This setup ensures high precision, making it ideal for projects requiring accuracy, such as woodworking. However, table saws are bulkier, less portable, and require more storage space, making them better suited for workshops rather than on-site use.
Disc cutters
Disc cutters have powerful motors and robust, sharp blades, making them ideal for easily cutting through tough materials like concrete, brick, paving slabs, and stone. Their high performance and durability make them especially suited for demanding projects where precision and strength are crucial. Whether you’re working on landscaping, civil engineering, or construction, disc cutters excel at slicing through hard materials quickly and efficiently.
Circular Saw Types Comparison Table
| Saw Type | Key Design Characteristic | Best Suited For / Ideal Application | Portability |
|---|---|---|---|
| Sidewinder/Worm Drive Saws | The motor sits adjacent to the blade (Sidewinder) or behind the blade, driving it via a gear for more torque (Worm Drive). | Standard, portable wood cutting. Great for straight cuts and general carpentry. | Highly portable hand-held tools. Great for on-site use. |
| Mitre Saws | A circular saw mounted on a swinging radial arm that is brought down onto the material. | Making highly accurate angled cuts, bevel cuts, framing, moulding, and trim work. | Semi-portable. Can be moved to job sites but requires a stable surface or stand. |
| Table Saws | A fixed cutting disc mounted directly onto a sturdy table where the material is pushed toward the blade. | High-precision projects like woodworking and making long, straight cuts in large sheet materials. | Low portability. Bulky and require more storage space, best suited for workshops. |
| Disc Cutters | Feature exceptionally powerful motors and robust, abrasive/sharp blades. | Slicing through tough, heavy-duty materials like concrete, brick, paving slabs, and stone. | Highly portable but heavy-duty. Ideal for landscaping, civil engineering, and construction sites. |
