Cordless Brushless vs Corded Amp
Power Source
Product A is a cordless tool powered by a 20V MAX battery system. It is sold as a bare tool, meaning you must provide your own compatible DEWALT 20V MAX batteries. This offers mobility without a power cord. Product B is a corded angle grinder with a 13-amp motor. It plugs directly into a standard electrical outlet. This ensures continuous power without worrying about battery charge levels. You choose based on whether you need wireless freedom or unlimited runtime from the grid.
Motor Type
Product A features a brushless motor. This design requires no brush changes and typically offers longer motor life and better efficiency compared to brushed motors. The absence of physical brushes reduces maintenance needs over time. Product B uses a traditional 13-amp motor. The data does not specify if this is brushless or brushed. Brushed motors are common in high-torque corded tools. You get advanced electronic efficiency with Product A, while Product B relies on a standard high-amperage motor for raw power.
Wheel Compatibility
Product A is designed specifically for 4-1/2 inch wheels. It accepts discs of this standard size. Product B supports a wider range, handling both 4-1/2 inch and 5-inch wheels. This flexibility allows you to use larger 5-inch discs for heavier grinding or cutting tasks. Both models share a 1/2-inch chuck size for wheel attachment. If you frequently use 5-inch accessories, Product B is the more versatile choice. Otherwise, both handle standard 4-1/2 inch operations.
Weight
Product A weighs 3.75 pounds as a bare tool. This lightweight design reduces user fatigue during overhead or extended use. Product B weighs 5.7 pounds. The additional weight comes from the heavier corded motor and internal components. While Product B is still described as lightweight for its class, it is noticeably heavier than the cordless version. You may prefer the lighter Product A for precision work or holding the tool for long periods. The heavier Product B may offer more stability during aggressive grinding.
Switch Type
Product A uses a paddle switch. This requires two actions to activate the tool, often providing better control and safety for one-handed operation. It also includes E-Switch Protection to prevent accidental restarts after power loss. Product B uses a trigger switch. This is the traditional grip-and-squeeze mechanism found on many power tools. It allows for variable speed control based on how hard you press. You might prefer the safety-focused paddle switch of Product A or the familiar trigger control of Product B.
Braking System
Product A includes a Kickback Brake and stops the wheel in 2 seconds or less on average. This electronic brake engages when a pinch, stall, or bind-up event is sensed. It quickly stops the wheel to reduce movement and shut off the grinder. Product B does not list a specific braking system in the provided data. Standard corded grinders may have mechanical brakes or none at all. If quick wheel stoppage is critical for your safety, Product A offers a distinct technological advantage with its electronic braking.

Frequently asked questions
Can the 20V MAX grinder use 5-inch wheels?
No, the DEWALT 20V MAX 4-1/2-Inch Brushless Grinder is limited to 4-1/2-inch wheels. Its design focuses on a smaller footprint for precision work. If you need to switch between 4-1/2-inch and 5-inch discs, you must choose the 13-Amp corded model instead. This specific brushless tool does not support the larger disc size.
Is the paddle switch better than a trigger?
The 20V MAX model uses a paddle switch for rapid shutdown safety. This allows you to stop the wheel quickly if you lose balance or encounter kickback. The 13-Amp model typically uses a trigger switch. Paddle switches are often preferred for safety in grinding applications where immediate power cutoff is critical for your hand position.
Which grinder is lighter to carry?
The DEWALT 20V MAX 4-1/2-Inch Brushless Grinder is lighter at 3.75 pounds. The 13-Amp corded model weighs 5.7 pounds. The cordless version is easier to hold for extended periods. Its compact dimensions also make it more maneuverable in tight spaces compared to the larger, heavier corded alternative.
Do I need to buy batteries for the 20V model?
Yes, the 20V MAX grinder is sold as a bare tool. It does not include a battery or charger. You must provide your own compatible DEWALT 20V MAX batteries. This option is ideal if you already own batteries from other tools in the same system, allowing you to save on initial costs.
Can I use this for stationary cutting tasks?
The 13-Amp 4-1/2 to 5-Inch Trigger Angle Grinder is better for stationary tasks. It is heavier and designed for stable, high-torque power. The 20V MAX model is built for mobility and handheld use. If you plan to mount the tool or perform fixed cutting operations, the corded amp model offers more stability.
What is the maximum wheel diameter for the 13-Amp model?
The 13-Amp model supports wheels up to 5 inches in diameter. It also accepts 4-1/2-inch discs, giving you flexibility in abrasive selection. This versatility allows you to handle various cutting and grinding needs without changing tools. The 20V MAX model is restricted to 4-1/2-inch wheels only.
