With the GFA18-H attached, the 18V Flexiclick delivers a robust 0.74 Ft.-Lbs. of impact energy (EPTA) and a 3/8 In. maximum drilling capacity into concrete. It features a no-load bpm of 0 to 5,400, providing professional performance in masonry-drilling applications, and comes with a removable side handle and depth gauge to increase tool control.

The 18V Flexiclick is connected ready for greater feature customization. Bluetooth connectivity can be activated using the optional GCY42 Connectivity Tool Module (sold separately). The system is also equipped with an efficient EC Brushless motor that produces up to 535 In.-Lbs. of torque; KickBack Control; and a 20+1 precision clutch.
