Ingersoll Rand air impact wrench, likely a 3/4" drive model such as the 259. Information off google lense, so apologies if I’m wrong? Please correct me! Was my grandads who was a mechanic. No longer with us.
The Ingersoll Rand air impact wrench is ideal for tight, hard-to-reach spaces in automotive work, gardening, and other household tasks requiring precise torque control.
