Bosch PROFACTOR GDS18V-770CN 18V 3/4" BITURBO Brushless Impact Wrench (Bare Tool)

The Bosch PROFACTOR GDS18V-770CN 18V 3/4-inch cordless impact wrench breaks free seized fasteners, loosens rusted structural bolts, and secures high-torque hardware in heavy industrial construction and fabrication settings. Engineered with a BITURBO brushless motor and drive-train system that delivers 770 ft-lbs of fastening torque and 1,250 ft-lbs of maximum breakaway torque, this 5.2-pound bare tool features an onboard user interface with three speed settings up to 1,750 RPM. Outfitted with an Auto Bolt Release mode to prevent dropped hardware and a 3/4-inch friction ring anvil with a thru-hole for secure socket retention, it equips commercial ironworkers, heavy equipment mechanics, and steel erectors with high-efficiency cordless fastening power.

**Battery and charger sold separately.

Best Used For:

  • Heavy Machinery and Commercial Equipment Maintenance: Loosening stubborn, rusted lug nuts and heavy-duty chassis bolts on industrial vehicles and construction machinery.
  • Structural Steel Erection and Ironworking: Driving and securing large structural bolts and high-torque fasteners across steel building frameworks.
  • Industrial Pipe Flange and Assembly Bolting: Fastening heavy commercial pipe flanges, machinery bases, and structural anchor plates quickly and safely.

Key Performance & Safety Features

  • BITURBO Brushless Technology: High-performance motor and drive-train system engineered to optimize power delivery when paired with high-capacity CORE18V batteries.
  • High-Torque Performance: Produces 770 ft-lbs of rated fastening torque and up to 1,250 ft-lbs of max breakaway torque for heavy industrial tasks.
  • 3-Speed Electronic Control: Integrated user interface allows operators to select between 0-800, 0-1,300, and 0-1,750 RPM to prevent fastener over-tightening.
  • Auto Bolt Release Mechanism: Automatically stops tool rotation once the fastener is unloaded to prevent nuts and bolts from falling during removal.
  • Friction Ring with Thru-Hole Anvil: Heavy-duty 3/4-inch square drive anvil ensures fast socket changes and positive socket retention under heavy vibration.

What's Included

  • (1) Bosch GDS18V-770C PROFACTOR 18V Connected-Ready 3/4 In. Impact Wrench (Bare Tool)
