18V Brushless Connected-Ready Freak 1/4 In. and 1/2 In. Two-In-One Bit/Socket Impact Driver Kit with (2) CORE18V 4.0 Ah Compact Batteries and (1) Connectivity Module

The Bosch Freak is half driver, half wrench, all impact. The GDX18V-1860C Two-in-One 1/4 In. and 1/2 In. Bit/Socket Impact Driver delivers results, with the two-in-one bit/socket drive that offers a 1/4 In. quick-change hex shank for bits, and a 1/2 In. square drive for sockets. The two-in-one bit/socket drive increases both convenience and power. Bits can stay conveniently inserted when using deep sockets, and more torque is transferred directly thru the 1/2 In. square drive anvil. There is no more torque loss through socket adapters or broken socket adapters. The impact driver’s efficient, powerful brushless motor produces up to 1,860 In.-Lbs. of torque and 0-4,100 impacts per minute. In addition to three speed/torque settings this impact driver also features special modes to help prevent work piece and fastener damage. The presets include modes for self-drilling metal screws and wood screws. Additional modes and customizations for specific screws and materials can be set and saved to the tool via the Bosch Toolbox App (connectivity module included). In reverse, with bolt mode activated, the Auto Bolt Release stops rotation when there is no load on the tool to help prevent accidentally dropping bolts and nuts during removal. In addition to customizing settings and modes, connectivity (module included), provides tool specific information and feedback. The variable-speed trigger provides accurate driving speed. It also has an LED light system to illuminate the work area. The kit features two CORE18V 4.0 Ah Compact Batteries, allowing you to keep the power and lose the weight.
