The Makita GWT09Z 40V max XGT Brushless 1-in. Square Drive D-Handle Short Anvil Impact Wrench is a cordless high-torque impact wrench built to replace pneumatic 1-in. impact wrenches on heavy equipment and large-diameter bolts. This is an impact wrench designed for heavy equipment maintenance, OTR truck service, commercial construction, pipe fitting, rail maintenance and oil and gas work. The model number is GWT09Z, and it ships as a bare tool, so batteries and charger are sold separately.

The headline number is 2,950 ft.-lbs. (4,000 N.m) of nut-busting torque, with 2,320 ft.-lbs. (3,150 N.m) of fastening torque. Makita rates it at up to 47% more nut-busting torque than a leading competitor battery-powered impact wrench. In practice, that means rusted wheel nuts on loaders and haul trucks, track bolts and structural connections come loose without dragging a hose and compressor to the machine.

A four-speed power selection switch covers 0-600, 0-700, 0-850 and 0-1,200 RPM with 0-1,200, 0-1,300, 0-1,500 and 0-1,750 impacts per minute. Pair that with three forward and three reverse Auto-Stop modes and you can run nuts down without over-torquing, or back them off without having them spin off the stud and disappear. A full speed mode function shortens the trigger pull needed to reach full speed, and the variable speed trigger stays smooth for controlled starts.

The tool is designed around handling at max torque. The 360-degree D-handle installs without tools and can be positioned quickly for the job, the short anvil keeps the wrench compact for maneuvering around equipment, and the overall length is 17-1/8 in. A rubber joint at the battery mount separates battery and tool impacts for anti-vibration protection, and a tethering ring is included for strap support or hanging the tool on equipment. Makita lists the weight at 24.6 lbs. with battery.

Durability features include a reinforced gear housing and Extreme Protection Technology (XPT), a set of integrated seals that channel dust and water away for use in harsh job site conditions. An LED light ring gives 360-degree illumination around the socket to cut shadows in wheel wells and under equipment.

It runs on Makita 40V max XGT lithium-ion batteries. XGT digital communication between tool and battery optimizes performance for up to 2X longer sustained power under heavy loads and protects against overload, over-discharge and overheating. A multi-layer contact interface keeps power delivery steady under high current, and rigid battery rails hold the pack in place under hard impacting.

Who should buy it: heavy equipment mechanics, fleet and OTR truck shops, steel and commercial construction crews, pipe fitters, rail and mining maintenance teams. If you already run XGT batteries, the tool-only version adds this wrench without paying for more packs.

Leave the Compressor in the Truck

The Makita GWT09Z 40V max XGT Brushless 1-in. Square Drive D-Handle Short Anvil Impact Wrench gives you 1-in. pneumatic-class breakaway torque on a battery.

• Who it's for: Heavy equipment, fleet and field service mechanics who loosen and tighten large-diameter fasteners every day.
• Why it stands out: 2,950 ft.-lbs. of nut-busting torque, Auto-Stop modes in both directions, and a short anvil with a 360-degree D-handle for control.
• Worth knowing: This is a 24.6-lb. tool with battery. It is built for big fasteners, not light automotive work. Batteries and charger are sold separately.

• What batteries does it use? Makita 40V max XGT lithium-ion batteries. It does not run on 18V LXT batteries.
• What is the difference between nut-busting and fastening torque? Nut-busting torque (2,950 ft.-lbs.) is the breakaway force for removing fasteners. Fastening torque (2,320 ft.-lbs.) is the rated tightening output.
• What does Auto-Stop do? Three forward and three reverse Auto-Stop modes stop or slow the tool automatically to help prevent over-tightening and nuts spinning off.
• Is a tethering ring included? Yes. A tethering ring is included for strap support and for hanging the tool on equipment.
