This 18V XR Brushless 50mm Magnetic Drill features technology that makes the drill up to 32% more powerful when using a XR FLEXVOLT DCB547 battery. Built to help prevent tool failure due to lost power, it securely attaches to metal by using a permanent magnet base that requires no electrical charge. To keep the user in control, the E-Clutch is designed to turn off when it detects rotation, part of the PERFORM & PROTECT family. The drill has 5 variable speeds for each of the 2 mechanical gears for a total of 10 speed settings to allow for a wide RPM range for a variety of applications.
