Rated 4.7 out of 5 by 3reviewers.
Rated 5 out of 5 by outstanding product, standard issue for our mill wrights March 20, 2014
Rated 4 out of 5 by Just put one into use with my Set Up Techs. Looking to see how it holds up under 24/7 use. Used to use the 1UMK4. It performed well, but under constant use didnt hold up as long as I thought it would. Looking forward to see how the heavy duty version performs. March 28, 2013
Rated 5 out of 5 by I have used many impacts an by far this is the best 1/2 inch impact on the market today. Ive used it daily for about a year now with no problems. With up to 650 ft pounds of tourque you can remove almost any bolt. August 15, 2012
