Professional 3/4" pneumatic impact wrench with 1,250 ft-lb working torque, lightweight magnesium housing at 8.1 lb, long anvil design, and sealed oil bath lubrication for heavy-duty fleet maintenance and equipment servicing.
The Snap-on 3/4" Drive Heavy-Duty Long Anvil Magnesium Air Impact Wrench (Model MG1250L) is a professional-grade pneumatic tool engineered for demanding applications in fleet maintenance and heavy equipment servicing. Featuring 1,350 ft-lb of bolt breakaway torque and 1,250 ft-lb of working torque, this impact wrench delivers exceptional power for loosening and tightening fasteners on large equipment and tires. The lightweight magnesium housing weighs only 8.1 lb, significantly reducing user fatigue during extended operation while maintaining superior control and precision.
This tool incorporates advanced engineering with a six-vane rotor for faster motor start-up and a powerful twin-hammer impact mechanism that minimizes downtime through fewer moving parts. The sealed-in oil bath lubrication system, filled with RED LINE® Synthetic Oil, ensures continuous lubrication and extended tool life. The 3-inch extended long anvil design with friction ring and thru hole accommodates larger fasteners and provides optimal reach for mid-sized fleet vehicles. Operating at 1,050 blows per minute with a free speed of 6,200 RPM, this wrench efficiently handles demanding service tasks.
Designed for professional technicians and fleet maintenance operations, the MG1250L features a one-handed reverse button for intuitive operation and an anvil stop function that prevents fastener ejection when the trigger is released. With a recommended 3/8-inch hose size and air inlet thread size of 3/8 NPT, this tool integrates seamlessly into existing pneumatic systems. The sound pressure level of 99.8 dB(A) and vibration level of 10.38 m/s² represent industry-standard performance metrics for heavy-duty impact wrenches.
