Description

Professional High-Torque Performance for Heavy-Duty Fastening

The Bosch IWHT180-B25-RT is the ultimate solution for professionals demanding raw power and precision in a cordless platform. Engineered for the toughest fastening applications, this tool delivers a massive 500 ft-lbs of torque, making it indispensable for driving large lag screws, setting concrete anchors, and removing stubborn, rusted lug nuts on automotive machinery. The tool features a robust all-metal motor and a spring-loaded hammer-and-anvil system. This design not only ensures high endurance but also provides consistent, controlled driving power up to 1,900 RPM and 2,100 IPM, significantly reducing the violent torque reaction often felt with standard impact wrenches.

This complete kit is powered by two next-generation CORE18V 4.0 Ah compact batteries, utilizing advanced 21700 cell technology to deliver the power of a traditional two-layer battery in a significantly lighter and more compact package. These batteries are equipped with Bosch's exclusive CoolPack 2.0 heat-management system, which cools the cells 15% faster and extends battery life by 135% compared to non-CoolPack models. With a durable metal front housing and a user-friendly 1/2-inch friction ring for rapid socket changes, this impact wrench is built to withstand the rigors of the jobsite while maximizing productivity.

Note: This is a manufacturer-reconditioned tool, certified to look and perform like new.
