The REL-425C hydraulic impact wrench was designed with an E-Z selector for use on both open or closed center hydraulic systems. It's lightweight (just 6.3 lbs.), makes it the ideal tool for use on utility pole construction.
The REL-425C delivers 375 ft.-lb. torque at 6 gpm making it great for drilling, loosening rusted hardware or tightening lag bolts with ease. The 1/2" square drive nose configuration will accept standard 1/2 inch square drive impact sockets.
