The SKIL 5” Random Orbital Sander (SR211601) is a powerful tool suitable for wood deck sanding and a variety of other sanding applications. It operates with a 2.8 amp motor, delivering up to 13,000 orbits per minute, ensuring a smooth finish on different surfaces. The corded electric power source ensures continuous operation without the need to recharge batteries, making it ideal for larger projects.

This sander features a compact, ergonomic design with a soft rubber grip, which minimizes hand fatigue and allows for comfortable extended use. At 3.44 pounds, it is relatively lightweight and easy to maneuver, even in tight spaces. The variable speed control adds versatility, enabling the user to adjust the power for different materials and tasks.

One of its standout features is the X-flow dust collector, which efficiently captures dust in a transparent, easy-to-clean container, ensuring a cleaner work environment. However, it may require frequent emptying during extensive sanding sessions. The inclusion of three sanding sheets adds value, though some users may need to purchase additional sheets for larger projects. As a drawback, the dust-sealed on/off switch, while practical, might become less responsive over time. This sander is best suited for DIY enthusiasts and homeowners looking for a reliable, efficient tool for wood deck maintenance and other sanding tasks.

The DEWALT Orbital Sander Kit (DWE6421K) is a corded, 5-inch sander designed to handle wood decks efficiently. It features a robust 3.0 amp motor that delivers consistent power, spinning the pad at 12,000 orbits per minute (OPM), which is ideal for achieving a smooth finish. The short height design allows users to get closer to the workpiece, improving control and precision.

The sander is equipped with a separate counterweight design, which minimizes vibration and enhances comfort during extended use. Additionally, the rubber over-mold in critical areas adds to the ergonomic design, making it easier to handle and reducing fatigue. The dust collection system is notably efficient, with an improved dust-sealed switch that prolongs the switch life and a one-handed locking dust bag for convenience. It is also compatible with DEWALT's dust collectors, ensuring a cleaner work environment.

However, this sander lacks variable speed control, which means users cannot adjust the speed for different tasks. At 4 pounds, it is relatively lightweight, which can be a plus for maneuverability but may require more effort for consistent pressure on larger surfaces. This sander does not use batteries, being a corded model, so it requires access to a power outlet. The DEWALT Orbital Sander Kit is a solid choice for those needing a reliable, comfortable, and efficient sander for wood decks, but users should be aware of its fixed speed and the need for a constant power source.

The DEWALT 20V MAX Sander is a versatile, cordless orbital sander ideal for wood deck projects. Powered by a 20V lithium-ion battery, it provides freedom from cords, making it convenient for larger areas. Its variable speed control ranging from 8,000 to 12,000 OPM helps to match the speed with the task at hand, ensuring efficient sanding. The brushless motor enhances runtime and efficiency, which is beneficial for prolonged use.

Weighing 4.29 pounds, it strikes a balance between being lightweight and robust, though some users might find it a bit heavy for extended use. The low-profile design allows for precise sanding, and the texturized rubber grip offers comfort during extended sessions. The replaceable 5-inch 8-hole hook-and-loop sanding pad makes paper changes quick and easy, which is convenient for different sanding tasks. The dust collection system includes a one-handed locking dust bag and the dust-sealed switch helps extend the life of the tool.

However, the dust port is designed to fit DEWALT's specific dust collectors, requiring an additional purchase if you don’t already have one. For other vacuum systems, an adapter is needed, which is also sold separately. Provided with a battery and charger, it ensures you're ready to go out of the box. This sander is well-regarded for its performance and durability, making it a solid choice for both DIY enthusiasts and professionals working on wood decks.
