IRWINIndustrial Tools 53700 Spiral Extractor and HSS Drill Bit Pouched Set, 6-Piece

Admittedly, this is one person's experience so take this with a grain of salt. But I am completely satisfied with this product and definitely recommend it. I had a small bolt sheer off flush in a delicate piece of machinery. After trying a few stupid ideas to get it out with my tools on hand, I gave in and ordered these. I was a tad bit skeptical, but turns out I shouldn't have been. I recommend tapping a small indent first with a center punch; this makes guiding the drill bit easier. I did this, and was soon well on my way. After drilling the pilot hole, I tapped in the extractor with a few gentle hammer taps, then used some pliers to hand-rotate the extractor. It came out flawlessly, which saved me from some very ugly hack saw work. Again, I highly recommend this. There are videos online that show some of secrets to using this tool; I imagine it's possible to screw this up, so learn first and then go for it.

Had 2 stripped hex screws in a tight spot. Tried all sorts of tricks and tools from rubber band to the easy out extractor tool but nothing worked until this. Based on my limited experience in using this set, I found it critical to drill slow and deep enough in order to hammer the extractor bit in for a tight fit. If the hole is not deep enough, the extractor won't fit tightly no matter how hard you hammer it. I used a vice grip to rotate the extractor bit to take the screw out. Took 2 screws out and the drill bit and extractor still looked sharp. I used the #1 extractor and the smallest drill bit in the kit.

It worked. As in another review, the drill bit drove the broken end deeper. Not a problem but I wondered if I could have saved time and effort with a left hand twist drill bit.

Bought this extractor kit after one of the main bolts on rear rack of my commuter bike (bicycle) sheared off. I'm a pretty aggressive rider and since this is my rain bike I have plenty of gear loaded on the rack. This kit is really amazing BUT make absolutely sure you pre-drill that pilot hole deep enough! First few tries just weren't enough and I was very frustrated with the extractor. Since this was a pretty small bolt and not all that long I ended up drilling all the way through. Hammered the extractor in there an BAM, backed out no problem.I suggest this quick test for pilot hole depth: If you hammer the extractor into the pilot hole and it's in there pretty well, doesn't wiggle around and feels solid, THEN you're ready to back it out. Otherwise the extractor will spin without biting.Good luck!

I had a Stainless Steel screw with the head broken off in the transom of my boat. Using the smallest drill in this kit along with cutting fluid and a good steady drill/hand, I was eventually able to drill a hole deep enough to use the extractor successfully. Stainless Steel is a pain to drill and takes time, but the drill bit did not burn out and/or go blunt.Using Extractors/easy-outs is not a job for everyone, it is easy to apply crooked pressure and break them off inside the hole. For bigger stuff it easier to weld on an extra bolt but I did not have this option as I was working with a small screw in fiberglass/wood. That said for what these are I found them to be of good quality.

In order to properly remove screws, you need left-handed drill bits in combination with a drill capable of "reverse mode". After drilling a hole counterclockwise, you can use the extractor bit.This may be a fake china clone kit. Only half of the bits are left-handed.

These extractors were VITAL for me, especially when in-store equivalents were MUCH more expensive. I had somehow managed to snap off the bolt holding on my ignition coil on my car - which was causing me a misfire. Luckily with amazon fast shipping and this set I was able to extract the bolt before any long drives needed to be taken.If this had not worked, I may have been forced to drill into my cylinder head, which is never a good option, the bolt came out in under 5 minutes, half of which was reading the instructions and looking at it.

It works! Used this on a very small bolt on my bike. (see pics)Used the smallest drill bit to drill into the bolt I was using. I then hammered in the 2nd smallest extractor and slowly turned it counter clock wise with a pair of vice grips by hand.Worked like a charm! Would highly recommend!

Pièces de remplacement pour mon kit Irwin. Malheureusement les forêts ne sont pas à gauche.

Thought it would come with reverse drill bits, nope. But it still got the broken bolt out so 5 stars.
