Contractor-Grade 18V Brushless 1/2-Inch Mid-Torque Fastening System with Auto Bolt Release and Friction Ring Socket Drive

The Bosch GDS18V-330CB25 18V Brushless 1/2-Inch Mid-Torque Impact Wrench Kit delivers professional-grade mechanical tightening velocity and breakaway force under demanding jobsite structural loads. Driven by a high-efficiency brushless motor, this cordless installation tool generates a stable 3,300 impacts per minute (IPM) alongside 330 Ft.-Lbs. of maximum fastening torque and 590 Ft.-Lbs. of breakaway torque. This mobile fastening solution resolves physical space constraints and user muscle fatigue problems during high-volume structural steel assembly, automotive lug nut removal, or heavy wood lag bolt driving by combining an agile 6.6-inch head length with a lightweight system profile of only 4.6 lbs. Supplied with two CORE18V 4 Ah Advanced Power batteries utilizing CoolPack 2.0 thermal regulation, this high-performance system incorporates Auto Stop protection to eliminate fastener over-tightening hazards.

Best Used For:

  • Structural Steel Erection: Securing heavy frame bolts, anchoring brackets, and coupling heavy iron structural components with uniform rotational force.
  • Heavy Timber Construction: Driving long lag bolts and structural self-tapping screws through multi-ply laminated veneer lumber (LVL) beams and heavy framing studs.
  • Automotive Fleet Maintenance: Removing rusted lug nuts, disassembling suspension assemblies, and servicing industrial equipment quickly without air hoses.

Key Performance & Safety Features

  • 590 Ft.-Lbs. Breakaway Force: Delivers heavy-duty breakaway torque to loosen stubborn, seized, or corroded industrial anchors and lug nuts rapidly.
  • Dual Pin Retention Drive: Integrates a 1/2-inch square drive anvil with both a friction ring and a thru-hole to allow quick socket changes and optimal safety.
  • Intelligent Auto Bolt Release: Advanced sensor algorithm terminates shaft rotation instantly when a fastener breaks free to completely prevent dropped hardware.
  • Auto Stop Tightening Mode: Embedded technology stops impact cycles the moment a fastener seats, mitigating the risk of material deformation and stripped threads.
  • CoolPack 2.0 Heat Management: Advanced battery housing structures protect the two included 4 Ah cells to manage heat dissipation during continuous load tracking.

What's Included

  • (1) GDS18V-330C 18V Brushless Connected-Ready 1/2 In. Mid-Torque Impact Wrench
  • (2) GBA18V40 18V CORE18V® Lithium-Ion 4 Ah Advanced Power Batteries

Pro-Tip: When shifting between high-speed structural bolt installations and precision assembly, utilize the onboard electronic console interface to alternate speed stages. Lowering the gear thresholds for light metric fasteners prevents high impact shock lines from fracturing low-grade structural materials.
