18v 1/4 inch hex impact driver (link) * 145 ft-lb * 1/4" hex drive collet * this is what I currently have vs 18v 1/2 inch impact wrench (link) * 485 ft-lb (forward) / 620 ft-lb (reverse) * 1/2" anvil socket Obvious I have the 1/4" impact driver (both 12v and 18v and both RIDGID) for many years. I just never thought of using it to work with tire lug nuts. Just recently I bought the impact socket adapter set (link). Since it has 1/2" drive socket, I just thought of could use it for lug nuts on cars/trailers? I just haven't attempt to try it (no time to get around it), so I am just going to ask without see it for myself. I see my mechanic has the 1/2" impact wrench (among many other tools) that he uses for his auto work. While I don't experience with the 1/2" impact wrench, I am going to ask questions... Specifically RIDGID brand, I read reviews that the 1/2" impact wrench don't work well with lug nuts. Some say it vary in torque measurements. Other say it doesn't even loose/break lug nuts. I wonder if I should look into buying one? Have you use such 18v 1/2" impact wrench (any brand)? With what I have, the 18v 1/4" impact driver, would this be suitable for lug nuts, as occasionally home driveway tire rotations? Along with this topic, I am sortof interested in looking at Husky torque bars (link). So, if you experience these, are those good to have? Do they last long time (is the torquing part forge in metal or involves rubber bushing that could weaken over time?)? Nonetheless, this is lifetime warranty. Again, would this work with 18v 1/4" impact driver (as it's 145 ft-lb) or need to use the 18v 1/2" impact wrench? Most likely I would use only the 100lb bar (for tires). Specifically, I am planning to buy this Husky 1/2" impact flip socket set (link) soon. Just saying. It's just that I am noticing I am now doing more of tire work (like brake work too), so I like to know if what I have is suffice? If I need to go with 24v or whatever, then forget it. I have portable air compressor, so I could buy 1/2" air impact wrench (but would rather avoid air hose). Also, I would need to buy a floor jack (mine got stolen years ago) and a 1/2" clicking torque wrench (probably a Craftsman brand).
