![]() ![]() "Brush" refers to the electrical contacts positioned around the rotating ring that deliver the current.Ī typical brushless motor, by contrast, has permanent magnets rotating around the ring, eliminating the problems of connecting a continuous current to a moving device. In order to keep torque output running at a consistent level, a typical motor needs to reverse current every time it rotates constantly. To understand why a brushless motor offers a clear advantage over a brush motor, it is important to understand how a power tool motor functions. The DEWALT XR is a line of heavy-duty power tools that features an advanced lithium-ion battery and a brushless motor design. They are sold in 20-volt, 60-volt, and 120-volt varieties. It's a completely cordless collection of power tools that allows for almost total freedom around the worksite for various projects. In addition, you can purchase from the DEWALT MAX line, which includes more than 100 products. There is a new, pre-owned, or eBay Refurbished DEWALT tool for almost every kind of application or job. The company offers both standalone tools and entire tool kits that come with extra accessories and features. You can find affordable DEWALT drill bits, nails, saw blades, abrasives, fasteners, and other accessories on eBay. Popular DEWALT ToolsĭEWALT has created an extensive lineup of both corded and cordless tools, including impact drivers, grinders, nailers, saws, air compressors, polishers, lasers, multi-tools, hammers, and various hand tools, many of which are designed to operate in outdoor conditions. Their use can range from personal projects to professional work-site applications. Made for both professional and highly experienced users, DEWALT power tools combine power, speed, resilience, and high performance. The adapter also will not work with FlexVolt batteries.DEWALT is an American company that specializes in power tools and accessories designed for construction, manufacturing, and home use. They do, however, give an amply large list of exceptions-likely for some of the reasons stated above. It lets you use 20V Max batteries in most of their 18V tools. As an example, the DeWalt DCA1820 battery adapter ( $39.99) claims compatibility with most DeWalt 18V tools. Just to cover our bases-yes, we know some battery adapters work without any issues. While a manufacturer may not know whether or not you used third-party batteries with their product, you still risk voiding a warranty if or when they find out. It can even shorten the lifespan of the tool. That can present a problem and run the tool hotter than expected. If a tool cannot communicate properly to a battery pack, you can end up in a situation where it asks for too much power. Manufacturers don’t like when you bypass the safety communication protocols built into either their batteries and/or tools. Using a tool with third-party battery adapters can have a similar effect. Bounce that drill off a roof onto concrete and you’re unlikely to get it serviced under the warranty. 3 – Potentially Voiding the Manufacturer’s Warrantyīelieve it or not, manufacturers actually care about how you use their tools and batteries. Nobody enjoys either a dead battery or a burned-up tool. Now you’ve created a potential “brick” pack that can no longer take a charge. What’s more-if a lithium-ion battery is “dumb” because the tool is smart, then putting it on a “dumb” tool means you can now drain the pack down below its nominal level. In both cases, all of the built-in protection that keeps both the tool and the battery from going so far that it damages itself is gone. Unfortunately, when you bypassed it with a battery adapter or voltage converter, you likely took away its ability to protect itself. Your car is most likely going to shut itself down before permanent damage occurs, and your cordless tool does the same. Just like the battery adapter, you’ve bypassed the electronic communications to do so. You’re just telling the tool to push the gas pedal farther. The same thing goes for these voltage boosters. ![]() See how long it takes for your temperature gauge to rise and idiot lights to illuminate. Tool battery adapters largely ignore the lines that govern safe use of a tool. Yes, we can push the tool and battery beyond what they’re rated for, but not for long and not without consequences. Just like the car, there’s an optimal operating range. This comes from extreme heat production in the motor and/or pack. Driving the motor beyond what it is designed to maintain will most likely result in failure.
