The Bosch HTH181-B25 18V High-Torque Impact Wrench with Pin Detent kit includes a heavy-duty wrench and two CORE18V 4.0 Ah batteries. The wrench is engineered for fastening high-torque nuts and anchors. It delivers up to 500 Ft.-Lbs. 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 2,100 ipm and up to 1,900 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 CORE18V 4.0 Ah Compact Batteries. Each keeps the power and runtime, while losing the weight, with 21700 cell technology. The CORE18V matches the power of the original two-layer 4.0 Ah battery with half the number of cells. It features the CoolPack 2.0 heat-management system.
