You want to make sure your hammer drill is powered by a brushless motor if you opt for a cordless model. You’ll get more versatility and great on-the-job flexibility, all in one handy drill. But at the same time, you can always switch over to the hammer functionality if you’re working on masonry. This is beneficial because it allows you to use the rotary mode for all of your typical drilling and driving needs. Typically, a hammer drill that comes with multiple working modes allows you to choose between rotary drilling and rotary-plus-hammer drilling. One hallmark of the best hammer drills is multiple working modes, or a selection switch that allows you to choose which mode you’d like to use. The side handle should be ergonomic with a comfortable grip. An auxiliary handle provides stability while you operate the drill and also makes the action more comfortable. The best hammer drill for concrete and other materials should include safety features for your protection. However, hammer drill brands with bigger motors will be larger and heavier. The bigger the motor, the more power it will deliver.
A typical hammer drill motor has about seven amps, while larger motors have about 10 amps. The more power you have, the quicker you can complete your task.
