Let me first say that Disney is not making an animated movie about power tools. Nemo Power Tools is in fact a real life company making waterproof power tools. The latest pro power tools can withstand being submerged for short periods of water, and are IP rated to resist water. However, water can still get in and cause long-term damage. Thats where Nemo power tools comes in making actual waterproof power tools. These tools look like theyrebuilt to the same specifications as mini submarines.
These power tools would not be as useful if they were corded. You can imagine the safety hazards associated with cords and extension cables. Nemo made the smart decision to make them cordless. This new cordless line is powered by 18V batteries and includes 3 drills, an impact driver, and
V2 Pool & Spa Edition submersibles up to 5 m. The next model in this line is V2 Divers edition rated at 50 m. The V2 Pool & Spa model and V2 Divers models both have the same brushed motors and drivetrains with 39 Nm Max torque (345+/- in-lbs) and the final drill in the line, the Special Ops model, which is waterproof to 100 meters. The Special Ops model may look the same although features 2x 6.0ah batteries as standard and features a brushless motor with a max torque rating of 54 Nm (478 in-lbs). Also worth noting is that the Special Ops and Divers models come with a pressure valve and pump so you can pressurize these models for deep diving. The impact driver as well as the pump are included in both models.
In terms of technical specifications, the angle grinder is the best of the group. It’s also the only one that is waterproof and cordless. The angle grinder is powered by 22V batteries. This is in contrast to the 18V models. They are more advanced than lithium-ion batteries and can run for 5 hours. Finally, it is completely brushless. Take the fact that this tool is waterproof out of the equation and it makes todays best 18V cordless angle grinders look weak in comparison.
These power tools are not cheap. The 5m Nemo Pool & Spa Edition starts at €99, with prices increasing from there. Although not inexpensive by any means and out of reach for the typical consumer, I find these to be reasonably priced. Although the price point of the angle grinder shoots through the roof at just under 1.5K ().
While these may seem like overkill for the everyday person and they are, they do offer a very practical use for those working in and around water day to day. I’m sure underwater welders and divers have used an underwater drill at one time or another. This seems to be the answer they have been looking for. It actually makes me wonder what theyve used in place of these before but thats a different topic. My only concern if any with these waterproof power tools has to do with my concern over heat build up. Water cannot get in so it is impossible for any other substances to get in. Venting is required to exhaust and vent internal heat buildup. It is fascinating to see how engineers and inventors managed to keep heat at a normal operating level without heating the tool. Even with modern vented cordless power tools, heat is a constant problem. They probably chose heatsinks that reach the outside of the units and provide water-cooled heat dissipation. But that’s just my guess.
Other than that, its good to see waterproof cordless power tools have hit the scene. Nemo Power Tools is not only a manufacturer of a waterproof drill or 3, but they have a great line-up that includes a few impacts and an angle grinder.
