Built By Professionals For Professionals
High Torque For Tough Jobs
The NitroCat® 1200-K Impact Wrench uses a smooth and powerful twin clutch hammer design, resulting in harder hitting impacts than a typical twin hammer design. This design makes this wrench perfect for high torque jobs on heavy-duty trucks and frames. The 1200-K churns out 1,295 ft.-lbs. of torque, which has made it a favorite of many NHRA Top Fuel race teams.
Durable and Lightweight
Using a Kevlar™ composite for the 1200-K Impact Wrench's housing adds toughness and durability without adding extra weight. The ergonomically designed handle adds to the user's comfort.
Innovative Features
More Power With Half The Noise
AIRCAT®'s patented tuned exhaust muffler allows discharged air to pass without developing back pressure, keeping more power and torque in the tool while significantly reducing noise. The 1200-K Impact Wrench runs at a quiet 86dB.
Easy To Use On Long Jobs
The handle has been designed to provide a comfortable grip and reduce stress and fatigue on your hands, wrists, and arms. The air exhaust flows out of the base of the handle, keeping dust and debris out of your eyes as you work. The easy operation flip lever lets you quickly switch from forward to reverse with a simple swipe.

According to the specs on the paperwork that came with my wrench, item 100107, this wrench has 900 ft-lbs torque in reverse, and three different settings in forward. I am very pleased with mine. I had two other inexpensive half inch impact wrenches, and this one breaks lug nuts loose in a flash while the other ones were still trying to break the first one loose.

The impact wrench is not rated with off or on torque by NitroCat. The industry standard rates at working torque only.

Will using a 1/4 male air hose fitting impede the proper volume of air to the gun? Is it necessary to use 1/4 mpt x 3/8 male air fitting?
