Break Free Stuck Fasteners and Manage Heavy Fleet Maintenance Natively with Single Hand Forward Reverse Controls
The DEWALT DWMT70773L 1/2-Inch Drive Heavy Duty Air Impact Wrench is an industrial-grade pneumatic fastening tool engineered to deliver up to 650 ft-lb of maximum breakaway torque. This heavy-duty air driver operates at a free speed of 7,500 RPM under a regulated 90 PSI pressure ceiling to accelerate high-volume assembly and disassembly cycles. Outfitted with a specialized single-hand directional selector switch and integrated shock-resistant rubber composite protective housing bumpers, this balanced 5.94-pound mechanical tool optimizes unassisted automotive chassis and industrial machinery tear-downs.
Best Used For:
- Automotive Fleet Service: Stripping away rusted lug nuts and stubborn wheel fasteners unassisted during high-volume tire rotation and brake servicing cycles.
- Suspension Component Tear-Downs: Extracting seized suspension alignment bolts and subframe hardware components without manual breaker bar leverage.
- Industrial Machine Assembly: Fastening high-tensile structural bolts securely across heavy equipment mount frames, industrial pumps, and metal factory rigs.
Key Performance & Safety Features
- Formidable 650 Foot-Pound Torque Core: High-output internal twin-hammer mechanical mechanism forces rapid impact energy waves to break down seized fasteners.
- Single Hand Directional Selector: Ergonomically placed rocker configuration facilitates quick thumb transition parameters between forward and reverse lines natively.
- Shock Resistant Armor Bumpers: Protective elastomer body inserts preserve internal alignment tolerances during accidental shop drops onto concrete flooring.
- Optimized Compressor Flow Matching: Precision air intake management regulates load consumption to 5.9 CFM at 90 PSI to extend workstation compressor cycles.
- Vibration Damping Grip Frame: Balanced polymer composite shell contours control tool tracking while reducing structural hand fatigue over long service shifts.
What's Included
- (1) DWMT70773L 1/2-Inch Drive Heavy Duty Pneumatic Air Impact Wrench Unit
- (1) Maintenance Bottle of Premium Pneumatic Air Tool Lubricant Oil

PRO-TIP: To preserve maximum anvil strike velocities and protect internal planetary valves from humidity corrosion, inject 4 to 5 drops of the bundled pneumatic lubricating oil directly into the 1/4-inch NPT air inlet port prior to each shop rotation shift. Keeping line moisture managed natively guarantees consistent 650 ft-lb break-away output ratings and extends hardware lifespan.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!

4/5 Stars
Size: 4 Panel-88'', Color: Black
Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.

Great product and worth the money.
Size: 4 Panel-88'', Color: Black
Portable and stable. Perfect size and gives me the privacy I need when working from home. Stability is great as long as you place the stands correctly it won't wobble. I love it.

Attractive
Size: 4 Panel-88'', Color: Grey
The assembled product is just as described. The screens look great! I am using them to hide the cluttered shelving in my garage. The area now looks quite neat Something I must say, though, is that the assembly was extremely difficult. I had to use a silicone spray and some pounding to get the A and B poles to fit together. Also, it required a great deal of strength to stretch and hold the fabric panels so that the bars inserted in each hem lines up with the screws inserted in A/B poles. I strongly recommend having a partner to help with the assembly.
while sc and screw into poles them once inserted intetchedtne end of each pole ( and B poles barely fit together. I used silicone spray on the end and then pounded them

It’s beige and not white. Once install - hard to disinstall. Need a drill to put it together
