Professional Automotive Impact Tool

The American Forge & Foundry 7660 is a heavy-duty pneumatic impact wrench built for professional automotive technicians. Its 1/2 inch drive handles overtightened lug nuts and seized fasteners in tire shops and general repair bays. A premium tungsten titanium alloy hammer and anvil extend service life under demanding daily use. The tool delivers 7000 RPM and over 500 ft-lbs of reverse torque for quick removal tasks.

Shop Air Integration

The wrench connects to a compressed air supply via its standard inlet, requiring an air compressor and hose rated for continuous pneumatic tool operation. An aluminum hammer casing protects internal components from shop-floor impacts and debris. A convenient forward/reverse switch allows rapid directional changes without removing the tool from the fastener. Adjustable throttle settings give the operator precise control over speed and power delivery for varied applications.

Sustained Shop Performance

Under continuous heavy use, the tungsten titanium alloy hammer mechanism resists wear better than standard steel components, maintaining torque output over extended periods. The aluminum casing dissipates heat effectively during long sessions of repetitive lug nut removal or heavy equipment maintenance. Consistent air pressure keeps the motor at its rated 7000 RPM without the power drop-off common in lesser alloys. The adjustable throttle prevents fastener damage during prolonged, high-volume workflows.
