Professional 3/4" drive air impact wrench with 1,250 ft-lb working torque, lightweight magnesium housing, and twin-hammer mechanism for superior control and durability in heavy-duty applications.
The Snap-on MG1250P is a professional-grade 3/4" drive heavy-duty air impact wrench engineered for demanding industrial applications. Featuring a powerful twin-hammer impact mechanism with a lightweight one-piece magnesium housing, this tool delivers 1,350 ft-lb (1,830 N·m) of bolt breakaway torque and 1,250 ft-lb (1,695 N·m) of working torque. The wrench is specifically designed for servicing large equipment and tires on mid-sized fleet vehicles, making it an essential tool for aviation, aerospace, military, defense, oil and gas, power generation, railroad, and general industry applications.
This air impact wrench incorporates advanced engineering features that ensure superior performance and durability. The six-vane rotor enables faster motor start-up, while the sealed-in oil bath lubrication filled with RED LINE® Synthetic Oil provides continuous lubrication and extended tool life. The pinned anvil design prevents fasteners from being thrown when the trigger is released, enhancing operator safety. With a weight of just 8.1 lbs and a compact 8-inch length, the tool offers exceptional control and reduces user fatigue during extended use.
The MG1250P operates at 6,200 RPM with 1,050 blows per minute, delivering consistent and reliable performance. The one-handed reverse button enables easy operation, while the 3/8" NPT air inlet accommodates standard air hose connections with a recommended 3/8" hose size. Sound levels of 99.8 dB(A) and vibration levels of 10.38 m/s² are well-managed for a tool of this power class. This professional tool is backed by Snap-on's commitment to quality and includes access to user manuals and repair parts support.
