Extractor HSS Broken Bolt and Damaged Screw Extractor 4 Piece Kit Comes with Case. Removes All Kinds of Screws and Bolts. Speed Out Style Dual Tip Design Requires No Drill Bits

take care not to overheat the drill bit

These bits drill thru the hardest of screws like a hot knife thru butter. They saved the day removing some self tapping screws that either were stripping out or busting the heads off. But these backed them out with ease.I used the drill on high speed and I completely over heated and blued the bits, after that they dulled out and only worked on one or two more screws. When I replace these I will take care not to overheat them and I believe they will last along time.They work best when the head of the screw is still there to keep bit centered, found it somewhat difficult to drill a headless screw without using a center punch.They drill in reverse...took a minute to figure that out. Make sure to drill the hole until it bottoms out for best results.

I ordered these to remove a damaged screw in a pistol grip.I did not need to use them since closer inspection showed the screw to be very loose and only slightly damaged.However, these should work well except for very tight or corroded screws which would require a hand impact driver before using these.I did mess with these a bit while deciding whether to keep or return and decided this set would be valuable for the type of damaged household screws I run into.Hence the 3 stars.If you need something for light use, these are handy.Just do not expect then to remove anything to tough.

When you use it correctly it has worked every single time. Great product because there were situations, in my business, when on a job site that would have taken an enormous amount of time to remove the screw and this got it in less than a minute! Imagine 12 screws that are stripped and rusted and you can’t dig them out or you will ruin the product you’re trying to remove? Use the tool the correct way and it works. It has worked for me every time.

ALL CAPS BECAUSE OF EXCITEMENT. THESE THINGS REALLY WORK. I FOLLOWED THE DIRECTIONS PRECISELY. WITH THE HELP OF THE BLACK DRILL BIT TO DRILL DOWN THE MIDDLE OF THE SCREWS, THEY CAME OUT WITH EASE. I'VE SEEN SO MANY VIDEOS OF WOOD EVEN METAL BUT I USED THESE FOR MY SERGER SEWING MACHINE. YES YOU HEARD ME RIGHT. OMG AND I DIDN'T BREAK ANY OTHER PARTS ON THE MACHINE EITHER. THIS TRULY DESERVES 10*S.

I was really hoping these would work for some stripped screws in my bathroom and kitchen cabinets. Unfortunately, I couldn't get a single stripped screw out with these bits, and I'm pretty handy with my tools. I'm amazed it has such a good overall rating. What I really need is a dremel tool to carve slots in the screw heads so I can get a flathead into them. I was looking for a cheap alternative with these bits, but these were just a waste of money.EDIT/UPDATE: I found a great and simple way to remove stripped screws that works consistently. I just use a rotary tool like a Dremel with a circular saw blade bit to carve a straight line on the top of the stripped screw. Then I simply use a flat head screwdriver or drill bit to remove it. Easy and works every time, so far at least, just wear goggles.

The screw I bought to remove with this kit is right between tnt two largest sizes, and I still haven't been able to remove it.

My husband said the m e talk was too soft and didn't work very well.
