    Comments about 12V Cordless XRP 3/8 in. Impact Wrench Kit:

    I am a ASE ceritfied Auto Mechanic and Crew Chief on a multiple car Legend race team. I use this impact everyday. I own a Snapon 3/8 impact, Matco 3/8 impact and a Milwaukee 3/8 impact and the Dewault is my prefered choice. It has good torque and power as well as long battery life. At the track there is no subsitute.
