Take a look at the Dewalt, I am not going to say bad things about the Hilti.. They have good products, all pro brands have.. But what I will say is you have up to 90 days ( depends where you are from in the world) to test the Dewalt impact and if you don't like it you get your $ back http://www.dewalt.com/tools/cordless-impact-driverswrenches-impact-drivers-dcf886m2.aspx
