How these alternatives compare
DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder
The DEWALT DCG413B weighs 3.75 pounds, making it lighter than the 4.2-pound WORX. It uses a paddle switch instead of the WORX’s likely trigger layout, which some users prefer for control.

It shares the 4-1/2-inch wheel size and brushless motor. Choose this if you value a lighter frame and paddle switch operation over an included battery kit.

DEWALT 20V MAX XR Variable Speed Angle Grinder
The DEWALT DCG410VSB offers variable speed control, a feature not listed for the WORX. It weighs 4.74 pounds and is a bare tool. The WORX includes a 2.0 Ah battery and charger. This DEWALT model also accepts 5-inch wheels, providing greater versatility than the 4-1/2-inch WORX. It features a paddle switch. Choose this if you need adjustable speed settings or larger wheel compatibility. It sacrifices the included battery and charger kit and adds weight.

DEWALT 20V MAX XR 4-1/2 - 5 in. Brushless Grinder Kit
The DEWALT DCG410WW1 is a kit that includes a battery, unlike the bare-tool versions of other DEWALT options. It weighs 10.3 pounds with the battery, significantly heavier than the 4.2-pound WORX. It accepts 5-inch wheels, offering more versatility than the 4-1/2-inch WORX. It features a brushless motor. This kit is ready to use out of the box. Choose this if you want a complete high-power setup without buying separate batteries. It gives up the lightweight portability and compact size of the WORX. It is best for users who prioritize a complete kit and larger wheel compatibility over easy handling.
DEWALT XR 4-1/2 to 5-Inch Variable Speed Grinder

Frequently asked questions
Which alternative is best for tight spaces?
The WORX 20V Brushless 4.5-Inch Cordless Angle Grinder is the top pick for lightweight tasks and tight-space access. Weighing only 4.2 pounds, it offers superior maneuverability compared to heavier competitors. Its compact 5.25-inch length allows you to reach confined areas easily. This model suits DIYers who prioritize portability over raw power or variable speed control.
Do these grinders include batteries?
Most listed models are sold as bare tools, meaning you must supply your own battery. The DEWALT DCG410WW1 kit is the exception, as it includes a battery for a ready-to-use setup. Other options like the DEWALT DCG413B and Milwaukee 2880-20 require you to purchase batteries separately. Check the product attributes to confirm if a battery is included.
Which model supports 5-inch wheels?
Several DEWALT models support 5-inch wheel compatibility, including the DCG410B and DCG410VSB. These grinders allow you to switch between 4.5-inch and 5-inch discs for larger cutting or grinding tasks. The WORX WX812L and standard DEWALT paddle switches typically use 4.5-inch wheels. Choose a 5-inch compatible model if you need versatility for larger projects.
Are brushless motors standard in these kits?
Yes, all listed alternatives feature brushless motors. This includes the WORX WX812L, DEWALT DCG413B, Milwaukee 2880-20, and other DEWALT XR models. Brushless motors provide longer runtime and increased durability compared to brushed alternatives. This technology ensures efficient power delivery and reduced maintenance needs for both professional and DIY users.
Which grinder is the lightest option?
The DEWALT DCG413B is the lightest option at 3.75 pounds. It is lighter than the 4.2-pound WORX WX812L and the 4.99-pound Milwaukee 2880-20. Reduced weight helps reduce fatigue during extended use. If you need a portable tool for overhead work, this DEWALT model offers the best weight-to-power ratio among the listed picks.
Which model has a paddle switch?
The DEWALT DCG413B, Milwaukee 2880-20, and DEWALT DCG410VSB all feature paddle switches. This switch type provides robust safety and control, allowing you to release the tool immediately if needed. The WORX WX812L likely uses a different trigger layout. Choose a paddle switch model if you prefer enhanced control and safety features during operation.
What is the highest RPM available?
The DEWALT DCG410B offers up to 9,000 RPM, providing high power for demanding tasks. This speed suits professionals needing efficient cutting and grinding performance. Other models like the DCG410VSB also feature variable speed control to adjust RPM as needed. Higher RPM generally means faster material removal, making these models suitable for heavy-duty applications.
Which is the best budget choice?
The Milwaukee M18 Fuel 4.5-Inch Grinder is listed as the best budget option. It delivers robust protection and compatibility for existing M18 battery owners. This model prioritizes safety features and motor longevity over weight savings. It is an ideal choice for professionals who need reliable performance without the cost of premium bare tools or kits.
