3/8 Inch Butterfly Impact Wrench

The Jet JAT-100 is a pneumatic butterfly impact wrench with a 3/8 inch drive. It is designed for mechanics and technicians who need a compact air tool for tightening and loosening fasteners in tight engine bays or under-dash areas. The butterfly throttle allows one-handed speed and direction control. This tool suits professional automotive repair and assembly work.

Thermals noise and power draw

As an air-powered tool, the JAT-100 produces no motor heat or electrical noise during operation. It draws compressed air from a shop supply rather than electricity, so there is no power consumption at the tool itself. Operating sound levels depend on the air compressor and exhaust routing used in the workshop. The tool body remains cool during extended use.
