10 Best Cordless Sanders 2025 in the United States

The DEWALT 20V MAX Orbital Sander is a robust, battery-powered sander designed for efficient and precise sanding. It features a brushless motor which enhances its runtime and efficiency, making it well-suited for various sanding applications. The variable-speed control ranges from 8,000 to 12,000 OPM, allowing you to adjust the speed based on your task, which is very handy for different types of wood or projects. The low-profile design ensures you can get close to your work, providing better control for detailed sanding jobs.

The dust-sealed switch and one-handed locking dust bag help keep dust at bay, although the dust collection is most effective when connected to DEWALT’s specific dust collectors (sold separately). The ergonomic design, with a texturized rubber grip, offers comfort during extended use, which is a big plus. However, it is sold as 'tool only,' meaning the battery is not included, so if you don't already own a compatible DEWALT battery, that's an extra cost to consider.

It comes with an 8-hole hook-and-loop sanding pad for easy paper changes, although some users might find the need to purchase additional accessories like the DWV9000 Universal Quick Connector for other vacuum systems. This sander is lightweight at just over 2 pounds, making it easy to handle for longer periods without causing strain. Given its features and user-friendly design, it is particularly beneficial for DIY enthusiasts and professionals who need a reliable and efficient cordless sander for various projects.

The Milwaukee Electric Tools 2648-20 M18 Random Orbit Sander is a solid choice for anyone looking for a reliable cordless sander, especially for tasks requiring fine sanding. One of its standout features is the portability provided by its battery power. With an 18-volt battery, this sander offers decent battery life, allowing for extended use without the hassle of cords. Additionally, its motor power is adequate for most sanding jobs, making it suitable for both DIY enthusiasts and professionals alike.

In terms of sanding speed, this model performs well. It provides effective and smooth results, which is vital for achieving a polished finish. The dust collection system is another strong point; it effectively traps dust, keeping your workspace cleaner and reducing the mess often associated with sanding.

Ergonomically, the sander is designed for comfort during use, which is essential for tackling larger projects without causing fatigue. It fits well in the hand, making it easy to maneuver. There are a few drawbacks to consider. While the battery life is generally good, it may not last as long as some users might expect, especially during heavy use. Additionally, the pad size and type, while fine for general sanding, may limit its effectiveness on larger surfaces or more intricate jobs. This sander might not be the best choice if you're looking for versatility across a broader range of sanding tasks.

The Bosch GEX18V-5B15 is a compact and powerful cordless random orbit sander that runs on an 18V lithium-ion battery with a 4 Ah capacity, offering good runtime for typical sanding jobs without the restriction of a cord. Its brushless motor delivers up to 10,000 RPM, providing strong sanding power comparable to many corded models. The 5-inch pad fits many sanding discs, and the hook-and-loop backing pad helps the disc conform to curved surfaces, enhancing versatility for different projects.

A standout feature includes the ergonomic palm grip design combined with vibration dampening, which makes it comfortable to hold and reduces fatigue during longer use. The soft-start technology ensures a smooth start without sudden jerks. Dust collection is thoughtfully designed with options for a dust bag or vacuum hose connection, helping to keep the work area cleaner, although using a vacuum hose may require extra equipment. Weighing about 1 pound, the sander is lightweight and easy to maneuver, especially in tight or hard-to-reach spots, and features a user-friendly on/off switch placed within easy reach.

While the battery life is generally good, heavy continuous sanding may drain the battery faster than a corded sander, so having a spare battery could be beneficial. The included medium grit sanding disc might be limited for some users who may want to purchase additional grits depending on their project needs. The price point is typical for quality cordless sanders but may be higher than entry-level options. Bosch backs the tool and battery with a solid warranty, providing added peace of mind. This sander suits DIY enthusiasts and professionals seeking cordless convenience without sacrificing power and control.
