Snap-on 1/2" impact with 18v battery and charger. Impact is one of the newer models (pic of model and serial # will give u all the info). It has been used a few times and has always worked perfect with no issues at all. Has great torque and power (I've used it on Lief spring bolts, lug nuts, and heavy equipment and it impressed me) new job just furnished me with all brand new pneumatic so I would like to get some of my money back on my electric snap ons. will consider trades for name brand tools, electronics, phones, or anything else that interest me. message for info or pickup and I'll respond asap
