Bosch IWHT180-B25 18V 1/2-Inch High-Torque Impact Wrench Kit

The Bosch IWHT180-B25 18V 1/2-Inch High-Torque Impact Wrench Kit is a cordless heavy-duty fastening solution engineered for securing concrete anchors, driving large timber lag screws, and removing seized lug nuts on commercial jobsites. Delivering 500 foot-pounds of maximum torque, a no-load rotational speed of 0 to 1,900 RPM, and an impact rate of 0 to 2,100 impacts per minute, this high-torque wrench features a spring-loaded hammer-and-anvil system encased in an all-metal front housing. Outfitted with a 1/2-inch friction ring anvil for rapid socket retention, two CORE18V 4.0 Ah compact batteries with CoolPack 2.0 heat management, an 18V fast charger, and a canvas contractor bag, this 5.2-pound tool executes high-stress mechanical assembly.

Best Used For:

  • Commercial Structural Fastening: Sinking heavy-duty wedge anchors and sleeve anchors directly into cured concrete slabs.
  • Heavy Equipment & Fleet Maintenance: Busting loose rusted structural bolts, suspension fasteners, and heavy vehicle lug nuts.
  • Timber Framing & Wood Construction: Driving long, large-diameter lag screws and structural wood fasteners through engineered timber beams.

Key Performance & Safety Features

  • 500 Ft-Lbs Industrial Torque Engine: High-output all-metal motor generates 500 ft-lbs of breakaway and fastening force for heavy structural fasteners.
  • Spring-Loaded Hammer-and-Anvil System: Absorbs violent torque kickback while delivering smooth, controlled impact force to the fastener head.
  • Dual CORE18V 4.0 Ah Compact Batteries: Next-gen 21700 cell technology doubles runtime compared to legacy batteries while keeping total weight minimal.
  • CoolPack 2.0 Thermal Management System: Advanced battery housing cools internal cells 15% faster to extend total operational lifespan by up to 135%.
  • 1/2-Inch Square Drive Friction Ring Anvil: Hog-ring style anvil geometry securely holds impact sockets while allowing quick manual socket changes.
  • All-Metal Front Gear Housing: Heavy-gauge metal nosepiece withstands high-altitude jobsite drops and harsh environmental exposure.
