3/8 inch Air Impact Wrench

This 3/8 Air Impact Wrench built at our factory. Have you heard of CNC heat treatment?The alloy steel parts of our products are treated with this process that's why it survives years in auto shops and production lines while hitting 720N.M torque every time. Don't take our word on safety–the EU's MD-CE certification stamp is right here on the housing.

Being factory-direct means we cut distributor layers to drop prices, not durability, while ensuring we have annual inventory stability for immediate global dispatch. You can contact our techs who had participated CIHF (2009-2016), CISMEF 2015, or AIFME 2012–they've tested our wrenches live. Why do many clients rely on us? These pneumatic impact wrenchs take constant abuse but won't quit mid-shift–that's what we mean by workshop-tested power that lasts with basic care.

Product’s Applications

Our development team designed this 3/8 inch Air Impact Wrench to handle jobs that stall others. Stuck brake caliper bolts? Engine bay fasteners and car interiors too cramped for standard tools? That’s daily reality in auto shops and motorcycle garages–and precisely where our compact pneumatic impact wrench bites hardest. What mechanics appreciate is how it fits: compact profile slots between wiring harnesses and suspension components when working inside car cabins or under fuel tanks.

You’ll see it solving problems beyond vehicles too. Production line techs fixing small machinery jams; Construction crews driving bolts on steel frames when overhead space is tight. Light enough for hours on ladders but powerful enough to split frozen bolts on generator housings or cable trays.

Product’s Feature And Details

1.Ultra-lightweight CNC-treated hollow spindle and twin hammer pinless system generates torque up to about 720 N.M.

2.Recessed cylinder amplifies air compression efficiency, maximizing torque even at low pressure.

3. Three-speed adjustable forward/reverse system tackles stubborn bolts or delicate parts effortlessly.

4. Press-style trigger ensures fatigue-free operation with precise control.

5. Honeycomb vents reduce noise to 78dB while boosting airflow for smoother pneumatic torque wrench performance.

6. PVC inner braided three-layer process air hose, sufficient air pressure supply and explosion proof, can withstand 30kg high pressure also with a special connector. Available in black and gray. If use with a 3/8’’inch pneumatic impact wrench, it is recommended to purchase a 8.5mm inner diameter.

7.Dual heat treated hex sockets, combined with integrated chrome molybdenum steel forging to ensure high toughness, wear resistance, and crack resistance. Features carbon black phosphating surface treatment for rust prevention and a special inner angle design that increases uniform contact area to prevent slipping and reduce nut edge wear.
