Milwaukee M18 6-1/2″ Circular Saw 2630-20 Review 2026

The DEWALT DCS570B is a 7-1/4 inch cordless circular saw designed to deliver the power and depth of cut of a corded saw with the portability of a cordless tool. Powered by a brushless motor, it maintains 5500 RPM even under load, ensuring clean and efficient cuts through various materials. This saw is ideal for professionals and serious DIYers who need reliable cutting performance on the go.

Standout features include the electric brake for enhanced safety, a bevel capacity of up to 57 degrees for versatile angled cuts, and a runtime of up to 330 crosscuts in 2x4 pine on a single charge with a compatible battery. The saw is lightweight at just 7.5 pounds, making it easy to handle and maneuver on job sites.

The build quality is typical DEWALT: durable and robust. Users report that the saw handles heavy-duty tasks like cutting 4x4s with ease, though the blade may require two passes for a full cut through thick material. The adjustment knobs for pitch and depth stay secure during use, adding to the overall reliability.

One drawback is that the saw performs best with a larger capacity battery (such as a 5 Ah or higher), which is sold separately. Additionally, as a bare tool, you will need to purchase a battery and charger if you do not already own DEWALT 20V MAX tools.

Overall, the DEWALT DCS570B is an excellent cordless circular saw that offers corded-like power and versatility. It is a top choice for those who prioritize performance and portability, especially for framing and general construction tasks.

The Milwaukee M18 FUEL 8 in. Metal Cutting Circular Saw (model 2982-20) is a powerful cordless tool designed for cutting steel and other metals with speed and precision. Part of Milwaukee's M18 FUEL system, this saw delivers the performance of a 15A corded saw without the hassle of a power cord, making it ideal for metal fabricators, contractors, and DIY enthusiasts working on jobsites or in shops.

At the heart of the saw is a brushless motor that spins the 8-inch metal-cutting blade at 4,000 RPM. Users report that it cuts through 1/2-inch steel effortlessly and faster than a standard circular saw cuts through wood. The saw also features REDLINK PLUS Intelligence, which optimizes performance and protects the tool from overload, overheating, and over-discharge, ensuring long life and reliable operation.

One standout feature is the integrated chip catcher, which retains most of the fine metal chips produced during cutting. While some chips still escape, the system significantly reduces mess compared to traditional metal cutting methods. The saw has a cutting capacity of 2-9/16 inches, making it suitable for a wide range of metal stock. It is slightly larger and wider than a typical carpenter's saw, but users find it comfortable to handle and well-balanced.

However, there are a couple of drawbacks to consider. The blade is not visible during the cut, so users must set up a guide to ensure straight cuts. Additionally, for best performance, especially when cutting thick material or making many cuts, a high-capacity battery like the 12Ah M18 FORGE is recommended. The saw is sold as a tool only, so you will need to purchase batteries and a charger separately if you do not already own M18 batteries.

Overall, the Milwaukee M18 FUEL 8 in. Metal Cutting Circular Saw is a top-tier choice for anyone who needs a portable, powerful metal cutting solution. It offers excellent cut quality, robust build, and the convenience of cordless operation. Despite minor setup requirements and battery considerations, it earns high marks from professionals and serious DIYers alike.

The FLEX 24V Brushless Cordless 7-1/4-Inch Rear Handle Circular Saw Kit (FX2141R-1J) is a powerhouse designed for professional framers and serious DIYers who demand cordless convenience without compromising on cutting performance. With a brushless motor spinning at 6200 RPM and a cutting capacity up to 2-5/8 inches, this saw handles everything from 2x4s to pressure-treated 2x12s with ease, as confirmed by multiple user reviews.

One of the standout features is the rear handle design with the blade positioned to the left of the motor. This configuration improves line of sight for right-handed users, making it easier to follow cut lines accurately. The saw also includes a built-in LED light to illuminate the workpiece, further enhancing precision in dimly lit job sites. The magnesium shoe and handle keep the tool lightweight yet durable, reducing fatigue during extended use.

The kit comes with a 10.0Ah Stacked Lithium battery and a 280W rapid charger, ensuring you spend more time cutting and less time waiting for a recharge. Users report impressive runtime and quick charging, which is a significant advantage over competing cordless saws. The adjustable dust port helps keep debris away from the cut line, improving visibility and cleanliness.

Build quality is excellent, with a robust magnesium construction and carbide-tipped blade included. The saw offers easy-to-read depth and bevel adjustments, and the spindle lock simplifies blade changes. The limited lifetime warranty (when registered within 30 days) adds confidence for long-term investment.

Potential drawbacks include the left-blade orientation, which may not suit all users (some left-handed users or those accustomed to right-blade saws might need an adjustment period). The saw is also heavier than compact cordless circular saws, though this is typical for rear-handle models. Additionally, the battery system is exclusive to FLEX, so you'll need to invest in their ecosystem if you don't already own FLEX tools. Overall, the FLEX FX2141R-1J is a top-tier cordless circular saw that delivers exceptional power, runtime, and build quality for demanding cutting tasks.

The Milwaukee M18 6-1/2" Circular Saw (model 2630-20) is a cordless bare tool designed for professionals who demand power and precision. It delivers 3,500 RPM, allowing for quick and clean cuts through tough materials like LVL headers, making it a reliable choice for framing, finishing, and carpentry work.

This saw features magnesium upper and lower guards that enhance durability while keeping the weight low. The soft-grip handle provides comfort and control during extended use, and the aircraft aluminum shoe ensures accurate rip cuts. Its lightweight construction reduces user fatigue without sacrificing strength.

Ideal for plumbers, electricians, and carpenters, this saw is versatile enough for a variety of applications. However, as a bare tool, it does not include a battery or charger, so users must have access to the M18 system. Additionally, no blade is included, requiring a separate purchase for immediate use.

Overall, the Milwaukee 2630-20 offers excellent power-to-weight ratio and build quality, making it a solid investment for tradespeople who already own M18 batteries and chargers.

The EXTBTFOR cordless circular saw is a compact, battery-powered saw designed for DIY enthusiasts and homeowners who need a portable cutting solution. Powered by a 20V 2.0Ah battery, it delivers 3400 RPM for efficient cutting through wood, soft metal, and plastic. The integrated laser guide helps ensure straight, accurate cuts, while the adjustable depth and 45° bevel provide flexibility for various projects.

This saw is ideal for light to medium-duty tasks such as cutting lumber, PVC pipes, or thin metal sheets. Its lightweight design at just 4 pounds allows for comfortable one-handed operation, making it a great choice for overhead work or tight spaces. The included three saw blades (HSS, TCT, and diamond) cover a range of materials, and the guide ruler further aids precision.

Build quality is decent for the price point, with an alloy steel blade and plastic handle. The dust pipe helps keep the work area cleaner, though it may not capture all debris. The battery and charger are included, but the runtime is not specified, so users may want an extra battery for longer sessions.

Drawbacks include the plastic handle which might not feel as robust as metal, and the limited cutting depth at 45° (1-1/8") which restricts thicker angled cuts. Additionally, the warranty details are not clearly stated, which could be a concern for some buyers.

Overall, the EXTBTFOR cordless circular saw offers good value for DIYers seeking a portable, feature-rich saw with laser guidance and multiple blades. It performs well for its intended use, though professionals may prefer a higher-end model with longer runtime and metal construction.
