Bosch GDS18V-330CN 18V Brushless 1/2" Mid-Torque Impact Wrench with Friction Ring & Thru-Hole - Bare Tool

The Bosch GDS18V-330CN 18V brushless 1/2-inch mid-torque cordless impact wrench breaks loose rusted automotive lug nuts, drives structural timber lag screws, and anchors heavy machinery into concrete. Driven by an advanced brushless motor generating 330 ft-lbs of maximum fastening torque, 590 ft-lbs of breakaway torque, and 3,300 IPM, this 3.5-lb mid-torque tool provides an outstanding power-to-weight balance for tight engine bays and overhead structural steel assembly. Equipped with a dual-retention friction ring and thru-hole anvil, 3-stage speed selection, Auto Bolt Release (ABR) to stop dropped nuts, Bluetooth connectivity readiness, and an integrated LED work light, it delivers high fastening precision and jobsite productivity.

**Battery and charger sold separately.

Best Used For:

  • Automotive Suspension and Wheel Service: Busting stubborn, corrosion-locked wheel lug nuts and suspension control arm bolts with 590 ft-lbs of breakaway torque.
  • Structural Timber and Framing Lag Fastening: Driving large-diameter lag bolts and ledger screws through dimensional lumber and laminated timber posts without pre-drilling.
  • Commercial Machinery and Concrete Anchor Setting: Torquing large diameter concrete screw anchors and structural steel flanged nuts to exact fastener specifications.

Key Performance & Safety Features

  • High-Torque Brushless Motor: Produces 330 ft-lbs of tightening torque and 590 ft-lbs of breakaway force to handle high-demand mechanical fastening.
  • Dual Retention Friction Ring & Thru-Hole: Allows quick socket swaps on the job while providing pin-detent thru-hole locking for safety tethering at heights.
  • Auto Bolt Release (ABR) Technology: Intelligently shuts off impact action once fastener tension is broken to prevent loose nuts and bolts from spinning off and dropping.
  • 3-Speed Electronic User Interface: Allows operators to toggle between three power levels to match speed and torque directly to fastener diameter and material hardness.
  • Connected-Ready Tool Architecture: Compatible with the optional Bosch GCY42 Bluetooth module for customizing torque presets and monitoring tool status via the Bosch Toolbox app.
  • High-Lumen LED Work Light: Projects a clear beam of light onto fasteners and dark machinery assemblies for maximum alignment accuracy.

What's Included

  • (1) Bosch GDS18V-330C 18V Brushless Mid-Torque 1/2" Impact Wrench (Bare Tool)
