500 Ft-Lbs of Torque for Your Toughest Fastening Jobs

The Bosch IWHT180-B25 is the professional's solution for tough, high-torque applications. It's engineered to deliver a powerful 500 Ft-Lbs of fastening torque, making it ideal for driving large lag screws, setting concrete anchors, or removing stubborn, rusted lug nuts. The robust all-metal motor and spring-loaded hammer-and-anvil system provide consistent, controlled driving power (up to 1,900 RPM and 2,100 IPM) without the violent torque reaction of other wrenches.

This complete kit is powered by two next-gen CORE18V 4.0 Ah compact batteries, which feature advanced 21700 cell technology. This gives them the power of an original two-layer 4.0Ah battery at a lighter weight, providing an optimized performance-to-weight ratio. The batteries also feature Bosch's exclusive CoolPack 2.0 heat-management system, which cools the battery 15% faster and provides 135% longer life than non-CoolPack batteries.

Key Features

  • High-Torque Motor: Delivers up to 500 Ft-Lbs of torque for driving and removing heavy-duty fasteners.
  • Compact CORE18V Batteries: Next-gen 4.0 Ah batteries provide 2x the runtime of previous 2.0 Ah batteries at a lighter weight.
  • Hammer-and-Anvil System: Spring-loaded design delivers user control and managed torque thrust.
  • Durable Construction: Features a metal front housing for jobsite toughness and a 1/2 In. friction ring for easy socket changes.
  • Lightweight Design: Tool weighs only 5.2 lbs (bare tool) for a superior power-to-weight ratio.
  • CoolPack 2.0 Technology: Advanced heat management provides 135% longer battery life.
