Have you ever found yourself in a situation where you needed a power tool to work underwater? Maybe you were fixing a pool cover or doing some underwater construction. Whatever the case may be, traditional power tools are not designed for such tasks. But fear not, because Nemo Power Tools has got you covered.

Nemo Power Tools, a Hong Kong-based company founded by entrepreneur Nimo Rotem, has introduced a range of handheld power tools that are completely waterproof. These tools are not only perfect for commercial use but also great for any water-related household task. In this article, we’ll take a closer look at the Nemo V2 Divers Edition cordless drill and brushless angle grinder to see why they are the best options for underwater work.

The Ultimate Guide to Waterproof Power Tools

The Nemo V2 Divers Edition Cordless Drill

The Nemo V2 Divers Edition cordless drill is a powerful tool that can be submerged up to 50 meters underwater. Before testing it underwater, I had the chance to try it out on dry land. I drilled holes, drove screws, cut pipe, and ground steel scraps effortlessly. The drill features two bright LED work lights, making it perfect for deeper waters. With a ½-inch corrosion-resistant keyless chuck, 16 torque settings, and dual gear speeds up to 1,500 rpm, this drill can tackle any task underwater. It weighs a little more than standard drill drivers but is hardly noticeable once submerged.

The Nemo Brushless Angle Grinder

The Nemo brushless angle grinder is another impressive tool from Nemo Power Tools. With a 22-volt 5-amp-hour battery and a powerful 1,500-watt motor, this angle grinder can handle cutting and grinding tasks underwater with ease. It achieves cutting speeds of 6,500 rpm underwater and 9,500 rpm on dry land using a 4.5-inch-diameter cutting or grinding wheel.

Testing the Tools Underwater

Now, let’s get to the exciting part – testing these tools underwater. To prepare the tools for submersion, they need to be air pressurized using a bicycle-style air pump. The pressure required depends on the depth of your work. Even at a modest depth of two feet in my bathtub, it didn’t take long to reach the necessary one bar of pressure.

Once the tools were submerged, I was amazed by how well they performed. The drill, with its bright LED work lights, made drilling underwater a breeze. The angle grinder cut through materials effortlessly, with cutting speeds of 6,500 rpm. It was a truly remarkable experience to see underwater power tools in action.

Ideal for Various Applications

The versatility of Nemo Power Tools makes them suitable for a wide range of applications. Scuba divers, pool and spa maintainers, boat owners, and even rescue divers can benefit from these waterproof power tools. Cleaning propellers, hulls, and waterlines no longer requires hauling out a boat to dry-dock. Simply put on your wetsuit, attach the wire brush to the drill, and jump in. The angle grinder is perfect for salvage work, grinding off rusted bolts, and underwater construction. These tools have even been adopted by fire departments, sewer-repair crews, and special-forces teams for their underwater needs.

Yes, the Nemo Power Tools are specifically designed for underwater use and are completely safe when used correctly. Always follow the instructions and ensure you pressurize the tools properly before submersion.
