DeWalt Palm Sander

The DeWalt DWMT70781L Palm Sander is a versatile and durable pneumatic tool that has become an essential part of my workshop. Having tested numerous sanders over the years, I find this model to be a reliable companion for various sanding tasks, particularly in automotive and woodworking applications.

One of the first features that stand out is its lightweight composite body design. Weighing only 32 ounces, this sander significantly reduces hand fatigue during extended use. This is especially beneficial when working on large projects, such as preparing car bodywork for painting or smoothing out furniture surfaces. The ergonomic design allows for a comfortable grip, making it easy to maneuver and control.

The sander operates at an impressive 12,000 RPM when set at 90 PSI, which provides efficient sanding performance. This high speed, combined with its 3/32-inch orbit, makes it ideal for fine finishing tasks. It's particularly effective for feather edging and color sanding with higher grit sandpapers. The 3/32-inch orbit reduces the likelihood of leaving noticeable sanding marks, which is crucial for achieving a smooth, professional finish.

One of the standout features of this model is the touch control trigger. This allows for adjustable power application, which is a game-changer in terms of control and precision. The trigger is easy to depress and provides a variable speed function, enabling me to slow down or speed up the sanding process as needed. This is particularly useful when transitioning between different types of surfaces or materials.

The stick-on pad design is another practical feature, allowing for quick and easy changes of sanding pads. While some users may prefer a hook and loop system for its convenience, I find the stick-on pads to be equally effective and readily available. The pad changes are straightforward, making the tool versatile for various sanding discs and tasks.

However, it's important to note that the tool requires a decent air compressor to function optimally. I use a compressor with a capacity that meets the tool's maximum power requirement of 90 PSI, ensuring consistent performance. Users with smaller compressors may experience issues with sustained power, as the tool demands a continuous air supply for peak performance.

Despite its many advantages, there are a few areas where the DWMT70781L could be improved. Some users have reported occasional air leaks from the exhaust, which might be a minor inconvenience. Ensuring proper installation and using silicone pipe wrap on the connector can help minimize air loss. Additionally, the absence of a dedicated case is a slight drawback. While the tool comes with a cardboard box that can serve as storage, a more robust case would be preferable for protecting the sander during transport and storage.

The tool also includes a small bottle of oil and an angled wrench for pad changes, which are thoughtful additions. Regular oiling is essential to maintain the tool's performance and prolong its lifespan. I've found that a couple of drops of oil keep the trigger mechanism smooth and responsive, preventing it from becoming an on/off switch.

For those concerned about noise levels, this pneumatic sander operates relatively quietly compared to other air tools. However, using ear protection during extended use is always a good idea to prevent hearing damage.

In terms of build quality, the DeWalt DWMT70781L does not disappoint. It's tough and durable, designed to withstand demanding applications. The composite body is not only lightweight but also robust, capable of handling the rigors of frequent use. This durability, combined with the tool's performance, makes it a valuable addition to any workshop.

Overall, I highly recommend the DeWalt DWMT70781L Palm Sander for anyone in need of a reliable and efficient sanding tool. Its lightweight design, adjustable power trigger, and high-speed operation make it suitable for a wide range of applications, from automotive bodywork to woodworking projects. While there are minor areas for improvement, the tool's performance and build quality far outweigh these drawbacks. Whether you're a professional or a DIY enthusiast, this palm sander is an excellent investment that will deliver smooth and consistent results for years to come.
