As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking for worx 20v brushless 4 5 cordless alternatives because the original tool has specific strengths and limitations. The WORX 20V 4.5-Inch Brushless Angle Grinder offers a slim design that fits tight spaces and features anti-kickback technology for safety. It runs at 8,500 RPM with a brushless motor, which provides efficiency and longer life. However, it is sold as a bare tool, meaning you need compatible batteries. It also lacks variable speed control, which may be necessary for delicate tasks or different material types.
The 6 alternatives listed here were chosen because their specifications overlap with the original model. You will find options with variable speed controls, different wheel diameters, or paddle switches for easier operation. Some brands offer higher torque or different voltage ecosystems if you prefer Makita or Milwaukee systems. These tools share the core cordless, brushless attributes but provide distinct features that might better suit your specific workflow. You can compare weights, RPMs, and safety mechanisms to find the right fit for your needs.
How these alternatives compare to the WORX
DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder
The DEWALT 20V MAX Brushless Paddle Grinder is significantly lighter at 3.75 pounds compared to the WORX’s 5.71 pounds. It uses a paddle switch instead of a trigger, which offers a different control feel. Both tools run at similar voltages and feature brushless motors for efficiency. The DEWALT model lacks the specific slim profile of the WORX but provides a more compact body for general use. It is a solid choice if you already own DEWALT 20V MAX batteries and want a lighter, durable grinder with kickback protection. It gives up the WORX’s unique slim design for a more traditional, balanced weight distribution.
DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder
This DEWALT model accepts larger 5-inch discs, whereas the WORX is limited to 4.5-inch wheels. This allows for more aggressive material removal and cutting depth. It weighs 4.59 pounds, making it slightly lighter than the WORX. The tool features a brushless motor and is part of the 20V MAX ecosystem. It lacks the variable speed control found in other DEWALT models but provides robust torque for heavy-duty tasks. If you need to cut thicker materials or use larger abrasive wheels, this is the better option. It sacrifices the WORX’s compact size for increased power and compatibility with larger standard discs.
DEWALT 20V MAX XR Variable Speed Angle Grinder
The DEWALT 20V MAX XR Variable Speed Grinder offers adjustable RPM settings, a feature the fixed-speed WORX lacks. This allows you to tailor the speed to the material being worked on. It weighs 4.74 pounds and features a paddle switch. The tool accepts 4.5-inch wheels and includes anti-rotation safety features. It is ideal for users who need precision control over grinding speeds. While it is heavier than some competitors, the variable speed capability provides versatility the WORX cannot match. It is a premium choice for those who already have DEWALT batteries and require adaptive performance for different tasks.
DEWALT XR 4-1/2 to 5-Inch Variable Speed Grinder
This DEWALT grinder combines variable speed control with the ability to use both 4.5-inch and 5-inch discs. It weighs 4.74 pounds and features a paddle switch. The variable speed dial allows for fine-tuned operation, unlike the WORX’s fixed 8,500 RPM output. It includes anti-rotation safety technology to enhance user control during kickback events. This model is best for professionals who need flexibility in wheel size and speed settings. It offers more versatility than the WORX but at the cost of a slightly larger and heavier form factor. It is a strong alternative for users needing adaptive performance in a single tool.
Makita 18V Brushless 4-1/2 to 5-Inch Grinder
The Makita 18V Brushless Grinder operates on an 18V platform, which differs from the WORX’s 20V system. It accepts both 4.5-inch and 5-inch discs, offering greater versatility in wheel size. The tool is compact, measuring 8.4 inches in length, and weighs no listed amount. It features a brushless motor and electronic clutch protection for safety. This model is ideal for users invested in the Makita 18V LXT battery ecosystem. It provides similar safety features to the WORX but with the added benefit of variable disc compatibility. It is a reliable choice for those who prefer 18V tools and need a versatile grinder for various applications.
Milwaukee M18 Brushless Paddle Switch Grinder

The tool weighs 4.99 pounds and accepts 4.5-inch discs. It includes an anti-vibration handle to reduce user fatigue during extended use.
