![]() You’ll notice it has longer battery life, and and a longer overall lifetime. The “XR” means “extended runtime.” To that end, this drill contains a brushless motor. The DCD790B ½” drill is part of the DeWalt XR lineup. DeWalt offers a 90-day money-back guarantee, a 1-year free service contract, and a 3-year limited warrantyĭEWALT DCD790B 20V XR Lithium Ion Brushless Compact Drill/Driver (Tool Only, No Battery).Comes with on-board bit holder and belt hook.Of course, lithium-ion batteries don’t have memory effect like Ni-Cads do, and they hold their charge for months in storage. The MAX battery technology has electronic controls to prevent overheating, overloading, and deep discharge. If you own an 18V DeWalt cordless drill, you may notice that the 20V drills run about 35 percent longer. Since the DCD780B is compatible with any DeWalt 20V MAX lithium-ion battery, pair it with a 4.0Ah or 5.0Ah battery for the longest runtime possible between charges. Just below the barrel is an LED work light that turns on when you press the trigger, and then turns off 20 seconds after you stop drilling or fastening. It has a large variable-speed trigger and an ergonomic grip. But unlike corded pistol grip drills, this one feels balanced. The DCD780B weighs 3.4 pounds by itself and measures 7.5 inches long. This may give you the traction you need to remove it. If you need to remove a stripped screw, try placing a rubber band across the screw head before you put the bit in place. The bit will continue to turn until it cams out, or slips out of the screw head. If you prefer to sink that screw as deep and tight as you can, choose a high setting. Once the screw starts to tighten, the drill will start clicking. If you are doing delicate work where you just want to set a screw without countersinking it or stripping it, choose a low setting. ![]() The higher the setting, the higher the torque, or twisting power, applied to the bit. In case you want a refresher on clutch settings, this is how they work. With its maximum torque rated at 350 unit watts out, this drill can handle up to 2” in wood and 1-3/8” in metal when using a hole saw. The 15 clutch settings allow for a fair amount of precision work. The two-speed transmission has a low gear of 0-600rpm and a high gear of 0-2000rpm. That’s important because this drill has power. It has a keyless ratcheting chuck with carbide inserts to keep bits from slipping. It’s made for homeowners or contractors that aren’t looking for a brushless motor.
