VESSEL Shock Driver Lately, are they called impact drivers? No. 2500 This is the model. The condition is as shown in the photos. It was only used once when disassembling a motorcycle. I've been told that the rotation cannot be switched, but it's stiff by design. Please refrain from purchasing if you don't know how to use it. People with strength might be able to do it, but it's impossible if you're not strong. At least, I can't do it like the instructions say. Push and turn. I will ship it set to loosen. I will ship with tracking.
