Looking Beyond the Milwaukee 2888-20 18V Cordless 4.5"/5"? 6 Alternatives Worth a Look

How each alternative compares

Makita 18V Brushless 4-1/2 to 5-Inch Grinder

The Makita XAG04Z-cr uses a brushless motor, which typically offers better efficiency and longer runtime than standard brushed designs. It accepts 5-inch wheels, matching the Milwaukee's largest capacity, but lacks the variable speed dial found on the 2888-20. Instead, it relies on automatic torque adjustment to prevent binding. This model is lighter at 4.5 inches in width, making it more compact in your hand. If you prioritize safety mechanisms and brushless efficiency over manual speed control, this Makita is a strong choice. It fits users who already have Makita 18V batteries and want a robust, safety-focused grinder without the need for variable RPM adjustments.

DEWALT DCG408B 4.5-Inch Cordless Grinder

This DEWALT model operates on a 20V MAX platform, offering higher voltage than the Milwaukee's 18V system. It features a brushless motor and a paddle switch, which differs from the Milwaukee's traditional trigger. The paddle switch can be easier to engage with a thumb, allowing for quicker start-stop cycles. It weighs 4.83 pounds, making it slightly lighter than the Milwaukee's 5.42-pound body. The tool is designed for 4.5-inch wheels only, so you cannot use larger 5-inch discs. If you already own DEWALT 20V batteries and prefer a lighter, paddle-operated tool, this option provides solid performance and safety features for frequent grinding tasks.

Milwaukee M18 Brushless Paddle Switch Grinder

The Milwaukee 2880-20 is part of the M18 Fuel line, meaning it uses a brushless motor for increased power and durability. It features a paddle switch, which contrasts with the trigger switch on the 2888-20. This switch type can be more comfortable for extended use and allows for one-handed operation. It weighs 4.99 pounds, which is lighter than the 2888-20. Like the 2888-20, it uses 18V batteries, ensuring compatibility with your existing power source. If you value paddle control and brushless efficiency within the Milwaukee ecosystem, this tool offers a refined experience. It is ideal for professionals who need precise control and robust performance in a slightly lighter package.

Makita 18V Brushless 4-1/2 to 5-Inch Angle Grinder

This Makita model is a bare tool compatible with 18V LXT batteries, just like the Milwaukee. It features a brushless motor for improved efficiency and runtime. The tool is designed for 5-inch wheels, matching the larger capacity of the Milwaukee grinder. However, it lacks the variable speed control found on the 2888-20, operating at a fixed speed optimized for grinding. It weighs 5.8 pounds, making it slightly heavier than the Milwaukee. This model is best for users who prioritize a larger grinding surface and brushless efficiency. If you do not need variable speed settings and want a reliable Makita bare tool, this option provides solid performance for standard grinding applications.

Milwaukee M18 FUEL 5-Inch Flathead Grinder

The Milwaukee 2886-20 is a flathead grinder, which gives it a low-profile body designed for tight spaces. It weighs only 1.2 pounds, making it significantly lighter than the 5.42-pound 2888-20. This model uses a paddle switch and a brushless motor for efficient operation. It accepts 5-inch wheels, matching the larger disc size of the Milwaukee. However, the flathead design changes the handling characteristics, which may take some adjustment. It is ideal for users who need to grind in confined areas where a standard grinder cannot fit. If you prioritize portability and access to tight spots, this flathead option offers unique advantages while maintaining the M18 battery compatibility you already own.

Makita 18V Brushless 4-1/2 / 5 in. Paddle Grinder

This Makita XAG11Z is a paddle-switch grinder, differing from the trigger switch on the Milwaukee 2888-20. It features a brushless motor for better efficiency and durability. The tool is designed for 4.5-inch wheels, so it cannot use the larger 5-inch discs supported by the Milwaukee. It weighs 5.8 pounds, which is heavier than the Milwaukee model. The paddle switch offers a different grip and control method, which some users prefer for extended use. It includes safety features like automatic torque adjustment and an electric brake. If you already have Makita batteries and prefer a paddle-operated tool with robust safety features, this model is a reliable choice for frequent cutting and grinding tasks.
