We had been Particularly amazed at how conveniently the drill drove holes in concrete without having a hammer drill function. Its three/8-inch ratcheting clutch has two speeds—the minimal velocity for higher torque and also the large velocity for fewer torque—and fifteen settings. The brushless motor gives a best speed of one,500 rpm. The Xtreme is just under six inches in size, making it ideal for Doing work in restricted spots or in which precision really counts. It's perfectly-balanced and it has a comfortable grip, a aspect we appreciated in the course of testing. There's also an built-in LED function light-weight, a belt clip to maintain the tool shut at hand, plus a gas gauge to Permit you understand how A lot battery cost remains.
