10 Best Orbital Sanders 2025 in the United States

The Bosch ROS20VSK 5-Inch Palm Random Orbit Sander is a corded electric tool known for its strong motor and reliable performance. With a power supply of 120 volts and a variable speed range between 7,500 and 12,000 OPM (orbits per minute), it gives you good control to match different sanding tasks, from rough to fine finishes. The 5-inch pad size is standard and works well for most small to medium projects, making it versatile enough for furniture, cabinetry, or DIY woodworking. Bosch includes features like a microcellular backing pad and an integral pad dampening system, which help reduce swirl marks and deliver a smooth finish — a plus if you care about the quality of your work.

Dust collection is handled efficiently with an on-board filtering system and a vacuum hose adapter, which keeps the workspace cleaner and reduces airborne dust, improving comfort and safety. In terms of ergonomics, the sander is lightweight (about 3.5 pounds) and has a soft-grip design that minimizes vibration, making it comfortable to hold during longer jobs. The tool comes with a carrying case for convenience and uses widely available hook-and-loop sanding discs, so finding replacements is easy.

One minor downside is that being corded limits portability compared to battery-powered models, and the 5-inch pad might be small for very large surfaces, requiring more time to sand. Also, while it’s durable and backed by a one-year manufacturer warranty, the tool’s release date from 2004 means it lacks some of the newer features found in modern sanders. For users seeking a high-quality, affordable sander with good dust control and ergonomic comfort, the Bosch ROS20VSK is a strong contender.

The DEWALT Random Orbit Sander (DWE6423) is designed for users looking for a reliable and efficient sanding solution. Its 3-amp motor delivers impressive power, spinning the sanding pad at speeds between 8,000 to 12,000 orbits per minute (OPM), making it suitable for a variety of sanding tasks. The variable speed feature allows users to adjust the speed according to the project needs, which is a significant strength for versatility.

One of the standout features is the separate counterweight design that minimizes vibration, enhancing comfort during use. This is beneficial for prolonged sanding jobs as it reduces fatigue. The improved dust-sealed switch is another strong point, as it protects the internal components from dust, resulting in better durability and a longer lifespan.

Dust collection is well thought out, with a dust port that fits directly onto compatible dust collectors, and an improved one-handed locking dust bag for easy maintenance. This makes it a great choice for users who prioritize cleanliness during their sanding projects. The sander's ergonomic design features a rubber overmold that enhances grip and control, which is essential for precision tasks. Additionally, its lower height allows users to get closer to the workpiece for better control. The DEWALT DWE6423 is corded, which can limit mobility depending on your workspace layout. While this does provide consistent power without worrying about battery life, some users may prefer a cordless option for more flexibility.

The Milwaukee Electric Tools 2648-20 M18 Random Orbit Sander is a battery-powered tool, which offers great convenience since it doesn’t need a power outlet to operate. It runs on an 18-volt lithium-ion battery, providing decent power and flexibility for various sanding tasks. However, the fact that batteries are not included could be a drawback for some users, as it involves an additional purchase.

The sander is lightweight, weighing only 2 pounds, making it easy to handle and reducing fatigue during prolonged use. Its compact dimensions (11"L x 6"W x 7"H) further enhance its portability and ease of use in tight spaces. This model is geared towards fine grit sanding, suitable for detailed and finishing work. The sander also features standard components like sandpaper and sander accessories, making it ready for immediate use upon purchase.

One area that could be improved is dust collection, as there is no specific mention of any advanced dust management features, which might be a consideration for users needing a cleaner work environment. Lastly, Milwaukee is a well-reputed brand known for durable and reliable tools, which adds to the product’s value. This sander would be a good fit for DIY enthusiasts and professionals looking for a portable, efficient random orbit sander.
