The Craftsman Impact Driver is a quality product that will last for many years. Most important of all, it's made in the USA! It really helps to loosens up rusted bolts.
Doing some restoration work on an old car and could not get the door hinges off. Found this, great price, and it worked. Took a few hits and off came the screws. The bits that come with it are sturdy. Do not use normal hammer, something like a 5 pound sledge/hammer made the job much easier.
If you own a Honda and do your own brakes this is a must have. Very simple to use.
I just got this but haven't used it yet. It's to have on hand for one of those "Gee I wish I had this tool" moments that end up costing you valuable time either coming up with another solution or driving to the store to buy it at full retail cost. I already had such a moment that was solved using a ratcheting T-driver and proper bit, but the head was only stripped. Had the screw body been rusted as well, I would have needed this. Now I have it. Yeay.
Anyway, some folks are claiming that it's not reversible, i.e. it only unscrews, not the opposite. Not sure why you'd need it to work both ways given its intended application--perhaps for the rare reverse-threaded screw, or to use with a screw removal tool--but it is indeed reversible.
Look at the top of the thick part of the tool, just above the retainer ring. The following is etched into the tool around its circumference (upside down):
"R -- -- L"
Just beyond this, where the tool narrows into a sort of collar, that the anvil fits into, there's an etched arrow that points in the direction of the above guide. You press down on either the anvil or collar, to twist the collar to align with either the "L" or "R", then release. "L" means CW or tighten screw/bolt, "R" means CCW or untighten screw/bolt.
Perhaps not all versions of this tool have this feature, but mine does. I have to replace the rotors and pads on an old car soon and the rotor's rusted pretty bad, so I might have to use this.
Half inch drive is to big. A 3/8 inch drive is much more useful and can handle anything the !/2 one can. Wake up and make the right change.
