The Bosch HTH181-B25 18 V high-torque impact wrench with pin detent kit includes a heavy-duty wrench and two core 18 V 4 Ah batteries. The wrench is engineered for fastening high-torque nuts and anchors. It delivers up to 500 ft-lb of torque. Its spring-loaded hammer and anvil system moderates torque reaction to allow for consistent driving power and control and the wrench is built with an all-metal motor that produces up to 2100 ipm and up to 1900 rpm. It offers a square drive 1/2 in pin detent and true flat anvil design for convenient changing of sockets. The kit includes two next-gen core 18 V 4 Ah compact batteries. Each keeps the power and run time, while losing the weight, with 21700 cell technology. The core 18 V matches the power of the original two-layer 4 Ah battery with half the number of cells. It features the CoolPack 2.0 heat-management system.
