Powerbuilt 1/2 Inch Drive Impact Driver Set Extractor Tool, Slotted or Phillips Screwdriver Bits, Remove Rusted, Damaged Screws - 648002, Large

Used on door lock actuator screws. At first I was starting to strip them so I bought this and with a little heat (to melt the locktite) they all came off after a few wacks. Would definitely recommend.

How did I live without this?! I’m a hobby mechanic, I restore cars, do my own maintenance on cars, ATVs, generators, etc. I run into a lot of wonky screws and I hate drilling them out. This tool is great! I use it on delicate parts like carbs (light taps!) and seized brake screws. Even on partially stripped screws I have good luck. Glad it’s part of my toolset!

This impact driver deserves a 5 really, but there are a few things that made me drop a star. First, the good: Succeeded where others failed- I borrowed my dad's old, never used impact driver from the 80's- a tekton precursor I believe. I beat on the thing for hours trying to remove my rotor screws (02 accord, rusted/seized). Two of them came out after an hour's worth of work. The remaining 6 didn't budge and were near stripping. I tried on several occasions with a can of liquid wrench and other penetrants handy. Nothing worked. Wanting to replace my brakes, calipers, and rotors, I needed the screws removed. I totally destroyed the other impact driver by beating on it endlessly, so I decided to buy this as a replacement. I gave it one last go with the old one (about 30 minutes worth) and decided to try this one... in about 5 bangs with the hammer, the screws basically fell right out. I was totally amazed but thought it had to be a one time thing... nope, each screw thereafter took only a few bangs and came out. In that regard, this tool deserves a 10 out of 5, it's that great! Why did it lose a star then? Two reasons. 1. The plastic sleeve holding the driver was busted before I opened the package. It could have easily fallen through and banged my toe- this tool is not light. I would definitely have preferred a sturdy blow molded storage case. 2. As other reviewers have warned, everything in backwards. L is to tighten, R is to loosen. I didn't believe this at first, but you can tell as soon as you hit the driver and try to turn it the wrong way. The instructions are even wrong. Since this is really the only function of the tool, it is hard to overlook incorrect instructions and markings.

Durable tool

Perfect tool for those difficult to remove screws that are in tight places. Saves hours of trying to heat, tap and twist. Excellent build quality. Durability will ensure long lasting product

Awesome product. I wanted to change the rotors and brakes on my Acura. These cars are notorious for seized up rotor screws that just wont budge. I tried this without paying attention to the instructions and kept wacking it into the screw and the screw still would not budge. I thought I was doing something wrong. Changed the bit direction (incorrectly) thinking I had it in the wrong position but the screw would still not move! Gave up and put the tires and calipers back on and was not able to finish the job. Very disappointed. Gave it one more shot but this time read the instructions and watched a youtube video....instant success! The thing you need to realize is if you are trying to loosen a stuck screw, turn the bit holder to the left, while turning the handle to the right. This will lock the bit into the loosening position. So when u finally try to loosen the screw by applying an anticlockwise loosening turning action to the handle, the bit will not move unless with the handle. Now suppose you turned the bit holder to the right (used for tightening) by mistake and tried to loosen a screw by turning the handle anticlockwise. The bit holder would automatically turn to the left and lock into its proper position for loosening. So once you have the position set, apply a dab of permatex anti seize around the seized screw head, wait a couple of minutes and then place the impact driver into the screw head with the correct bit inserted into the bit holder. Apply a steady anticlockwise twisting action to the drivers handle with your left hand and use a 32 oz hammer to wack the driver 3-5 times with your right hand. You must continuously apply the anticlockwise twisting action with your left hand (switch hands for lefties). I CANNOT STRESS HOW IMPORTANT IT IS TO CONSTANTLY APPLY AN ANTICLOCKWISE TWISTING ACTION TO THE HANDLE WHILE WACKING THE DRIVER. It did not work for me until I did this important step! After 3-5 firm wacks you will feel the handle give a little as the screw breaks loose. Give it another 1-2 wacks while twisting and you have now successfully loosened the screw you could have sworn was not gonna budge no matter what you did 5 minutes ago. I hope that helps and good luck!

Works as intended. Worth the purchase.

3/12/2016 The main impact body works fine. does exactly what i needed it to. Removed the screws off of my 09 honda civic and then used it to put them back on. It feels sturdy and I had no issues with it. Edit: 3/16/2016 Started working on my rear rotors and one of the screws was really in there (due to rust). Used the Philips head screw bit and it snapped off on the 3rd tap. Now I have to figure out how to get this broken bit head out of the screw. Really pissed about that. The main body of this bit is fine, it's just the bits that come with it are cheap crap. Purchased this on 3/11/2016 it is now 3/16/2016.
