The ergonomic rubberized handle and lock-off switch ensure comfortable one-handed operation and safety. The saw is lightweight at just 4.36 pounds, reducing arm fatigue during extended use. The dust extraction port is a thoughtful addition, keeping the work area clean when connected to a vacuum.
Some users report that the laser guide can be difficult to see in bright conditions or may require a bit of trial and error to activate. The saw can bog down on thicker cuts, especially in dense hardwoods or when cutting near its maximum depth. Additionally, a few customers mention that Workpro's warranty support is limited, so purchasing an extended warranty may be wise.
Overall, the WORKPRO mini circular saw offers excellent value for its price, combining power, portability, and a comprehensive kit. It is ideal for DIYers and light construction projects but may not replace a full-size saw for heavy-duty framing. If you need a versatile, cordless saw for occasional use, this is a strong contender.
Pros
- High 3,500 RPM for fast cutting
- Durable magnesium guards resist damage
- Comfortable soft-grip handle reduces fatigue
- Precise cuts with aircraft aluminum shoe
- Compatible with Milwaukee M18 battery system
Cons
- Bare tool requires separate purchase of battery and charger
- 6-1/2 inch blade limits depth of cut compared to full-size saws
- No electric brake included for faster blade stopping
The Milwaukee M18 2630-20 is a 6-1/2 inch cordless circular saw designed for professionals who demand power and durability without the cord. As a bare tool, it is ideal for tradespeople already invested in Milwaukee's M18 battery platform, offering a cost-effective upgrade for framing, plumbing, electrical, and carpentry work.
Standout performance comes from its 3,500 RPM motor, which powers through LVL headers, plywood, and dimensional lumber with ease. The magnesium upper and lower guards provide superior impact resistance and protection for the blade, while the aircraft aluminum shoe ensures stability and accurate rip cuts. Users will appreciate the soft-grip handle that reduces vibration and fatigue during extended use.
Build quality is top-notch with Milwaukee's signature red finish and robust materials. The saw weighs 7.28 pounds, making it manageable for overhead cuts, though it is slightly heavier than some competitors. The 6-1/2 inch blade offers a good balance between cutting depth and portability, but it cannot match the depth of a 7-1/4 inch saw for thick stock.
A potential drawback is the lack of an electric brake, which means the blade spins down gradually after release. Additionally, as a bare tool, you must supply your own battery and charger, which adds upfront cost if you are new to the M18 system. However, for existing Milwaukee users, this saw is a smart addition.
Overall, the Milwaukee 2630-20 delivers professional-grade cutting performance and durability in a compact cordless package. It earns a strong recommendation for contractors and serious DIYers who value power, precision, and reliability on the job site.

Standout features include a brushless motor that provides up to 47% more power than the previous DCS575 model, enabling it to cut through pressure-treated lumber and plywood with ease. The electric brake stops the blade quickly after the trigger is released, reducing the risk of accidents. An integrated LED light casts a bright beam on the cut line, improving accuracy in dimly lit job sites or tight spaces.
Build quality is typical of DEWALT: a rugged magnesium shoe and a durable housing that can withstand job site abuse. The saw has a maximum cut depth of 2-9/16 inches at 90 degrees and a bevel capacity of 57 degrees, with positive stops at 22.5 and 45 degrees for common angle cuts. The rafter hook is a practical addition for hanging the saw during breaks, keeping it within reach.
One drawback is the weight: at 8.2 pounds, it is heavier than some cordless competitors, which may cause fatigue during prolonged overhead use. Additionally, as a tool-only model, it requires a separate purchase of a battery and charger, adding to the initial investment. The saw is also limited to the FLEXVOLT system, so it cannot use standard 20V MAX batteries.

One drawback is that this is a tool-only purchase, meaning you need a DEWALT 20V MAX battery and charger (sold separately). This can increase the upfront cost if you are not already invested in the platform. Additionally, some users may prefer a lighter saw for overhead or prolonged use.
Overall, the DEWALT DCS590B offers exceptional power, runtime, and safety features at a competitive price.

Buying Guide: What to Look for in a Cordless Circular Saw
Motor Power and Speed
The motor determines how quickly and cleanly your saw cuts through materials. Brushless motors, like those in the SEESII Brushless Cordless Circular Saw, deliver higher efficiency and longer runtime compared to brushed versions. Look for a no-load speed of at least 4,500 RPM for general cutting tasks. Higher RPMs (up to 6,500) allow smoother cuts in dense wood or metal.
For automotive applications, a saw with a powerful motor can cut through steel brackets or aluminum sheets with ease. The Milwaukee M18 Cordless Lithium-Ion 6-1/2″ Circular Saw offers 3,500 RPM, ideal for tough materials like LVL headers.
Blade Size and Cut Depth
Blade diameter directly affects the depth of cut. A 7-1/4-inch blade, like the one on the DEWALT FLEXVOLT 60V MAX Circular Saw, can cut up to 2-9/16 inches at 90 degrees, making it suitable for framing and thick lumber. Smaller 4-1/2-inch saws, such as the WORKPRO 20V Mini Circular Saw, are lighter and perfect for trim work or cutting thin materials. Consider the maximum depth at both 90 and 45 degrees to ensure versatility for different projects.
Battery System and Runtime
Cordless saws rely on battery technology for power. Lithium-ion batteries with capacities of 4.0Ah or higher provide extended runtime. Models that come with two batteries, like the SEESII Brushless Cordless Circular Saw with 2×4.0Ah batteries, allow you to work continuously by swapping packs. If you already own tools from a certain brand (e.g., DEWALT or Milwaukee), stick with the same battery platform for interchangeability.

Ergonomics and Safety Features
A comfortable grip reduces fatigue during prolonged use. Look for rubberized handles and lightweight designs (under 5 pounds for mini saws). Safety features like electric brakes (stops the blade when trigger is released) and lock-off switches prevent accidental starts. The DEWALT 20V MAX XR Brushless Circular Saw includes an electric brake for precise cuts and added safety.
