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

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.

The Powerbuilt mini impact work great. I need to lubricant the mechanism then it stop sticking.

Exelente

High quality and fast shipping.

This did the job! The bits are not very durable as other have posted but the tool itself worked like a charm. I just had to get comfortable with swinging the hammer hard enough. I handled it like a pro.

working on motorcycle controls and stuck Phillip head bolts; two hits on the impact driver and each one loosened; AND the head comes off to expose a 1/2" socket head

Tool worked, but the bits do not last at all. They broke after only a few impacts.
