Makita GWT08Z 40V Max XGT Brushless Cordless 1/2 Inch Mid-Torque Impact Wrench Bare Tool

The Makita GWT08Z 40V Max XGT Brushless Cordless 1/2-Inch Mid-Torque Impact Wrench operates as a heavy-duty automotive and structural fastening power tool engineered to break loose seized suspension bolts, run down timber lag screws, and torque wheel lug nuts. Driven by a digital brushless motor delivering 810 ft-lbs of nut-busting torque and 560 ft-lbs of maximum fastening torque, this 40V impact wrench features a 1/2-inch square drive with a detent pin anvil, an electronic 4-speed selection switch (up to 2,300 RPM and 2,900 IPM), and a net tool weight of 6.0 pounds with battery. Built with 3 forward and 3 reverse auto-stop rotation modes, XPT dust and moisture resistance, and an ultra-compact 6-11/16 inch head length, this cordless wrench accesses tight steering knuckles and equipment nodes.

**Battery and charger sold separately.**

Best Used For:

  • Automotive Suspension & Undercarriage Service: Busting loose rusted ball joints, control arms, and rusted lug nuts using 810 ft-lbs of breakaway nut-busting torque.
  • Structural Steel Bolting & Timber Framing: Fastening structural steel plates and driving heavy timber lag bolts with 560 ft-lbs of maximum fastening torque.
  • Restricted Access Mechanical Nodes: Maneuvering into narrow wheel wells, subframes, and machinery chases using the short 6-11/16 inch body length.

Key Performance & Safety Features

  • 810 Ft-Lbs Breakaway Nut-Busting Torque: High-output brushless motor generates massive reverse force to cleanly break loose frozen bolts and stubborn hardware.
  • 4-Speed Electronic Selection Switch: Digital power selector adjusts speeds up to 2,300 RPM and 2,900 IPM to prevent over-tightening small fasteners.
  • Forward & Reverse Auto-Stop Rotation Modes: Features 3 forward and 3 reverse auto-stop settings that cut power or slow rotation once friction breaks to prevent dropped nuts.
  • Extreme Protection Technology (XPT): Internal protective seals channel water droplets and jobsite dust away from sensitive motor electronics.
  • Ultra-Compact 6-11/16 Inch Length: Short head profile slips easily between tight engine mounts, suspension links, and framing studs.
  • Flexible Vibration-Isolating Battery Joint: Rubberized battery connection dampens impact vibration to protect terminal contacts from mechanical stress.

Pro-Tip: When backing off lug nuts or subframe bolts in tight wheel wells, engage one of the 3 reverse Auto-Stop modes. The GWT08Z will deliver full 810 ft-lbs breakaway torque to break friction, then instantly shut off or slow down, preventing loose nuts from spinning off the detent anvil and dropping into dark shop drain grates.
