Why this one
Composite body
The composite body keeps the weight down while staying tough enough for professional shop use.
3/8 and 1/2 inch drive
Available in 3/8 inch and 1/2 inch drive, sold individually, so you can match it to the impact sockets you already carry.
1/2 inch model output
The 1/2 inch model has a twin hammer mechanism for up to 960 Nm (708 ft-lb) maximum torque, with a free speed of 6800 rpm.
Runs on compressed air
Compressed air gives consistent output with no battery to manage. Connect an air hose, set your regulator and it's ready.
Read the full description
For jobs that demand more finesse than a full-size 1/2 inch driver can offer, this Teng Tools 3/8 inch drive model puts controlled pneumatic power into a compact, lightweight package. The composite body shaves weight without giving up the toughness that professional shops require.
The 3/8 inch drive accepts the impact sockets most technicians already carry, so there is no added cost to get started. It covers a practical range of mid-size fasteners — intake manifold bolts, valve covers, alternator brackets, interior trim hardware, and similar work where a smaller drive fits the application better than an oversized one.
Because the tool runs on compressed air, you get consistent output with no battery management and no downtime between vehicles. Connect a quality air hose, set your regulator, and the wrench is ready to perform all day long. The straightforward pneumatic drivetrain also keeps maintenance simple for experienced technicians who prefer air impact tools over cordless alternatives.
The composite housing translates directly into less fatigue. When you are reaching behind an engine or working overhead inside a cab, every gram matters. A lighter tool means steadier aim and less wrist strain at the end of a demanding shift.
This is a single-tool purchase built for professionals who know exactly what they need. No socket bundles, no carrying case markup — just a reliable pneumatic wrench ready to earn its place on your cart from day one.
