Craftsman  4 pc. Drill-Out Power Extractor

Simple to use. Just drill on one side of the bit. Flip it over and extract broken bolt. Great tool.

I have many craftsmen tools and i love them. I just recently bought an extractor kit and tried to use it for taking out a head bolt on my brothers car. I was unable to extract the bolt from the head and it took a long time just to drill down far enough to flip the extractor over and use it. When we finally got it drilled out and used the extractor I slowly turned it in and it grabbed. I continued to slowly turn the bolt and it would not give. Eventually I broke the extractor in the head. I love my Craftsmen and I hate to give a bad review but we need to figure out a tool that can withstand the abuse of hardened steel. I will continue to buy from Sears and Craftsmen thank you gor all your hard work. Jason R. Lunsford

One of the bolts holding the alternator in my car sheared off.  Rather than pay a mechanic $300, I bought the extractor set for about $40 and a new bolt for $3.  I had to re-read the instructions several time as the first part of step 2 didn't make any sense -- until I opened the package and looked at the bits.  I was a still little apprehensive because the last thing I wanted to do was make the broken bolt worse and have an even more expensive repair.  I also read a couple of the reviews on this site.

Following a tip from another reviewer, I pre-drilled a smaller hole with a conventional bit.  Then I used the power extractor as instructed.  The bolt came out quickly and easily.

This is a great set of tools to have on hand!

I bought this extractor to remove two screws that had the heads rusted off. It was difficult to get the hole in the screw drilled and then when I finally got it in the extractor broke in half. The shaft that was lodged in there was strong enough to dull every additional bit I used on it. If you have an especially difficult bolt make sure you buy a stronger extractor.

very expensive and totaly useless. i had one of the oil filter's cap screws (ATV) broken, it seemed to be not a big deal, just needed a right tool to take care of a problem so decided to buy this easy-out set. it left me extremely disapointed after the first try to use it... i finally got it out, but using simple 30 cent drill bit, not this 30 dollar piece of s....

These extractors work very well IF the bolt or screw threads are NOT frozen. If you broke the head off trying to unscrew the bolt then the threads are frozen and these will have little chance of working. HOWEVER if you broke the head off by shearing it or the head bottomed out before the thread did then these will work like a dream. In fact some will back out just by using the reverse (left handed) drill bit end. Good Luck

It works well on larger screws. Screws with smaller heads can't be removed easily.

I've used screw extractors for many years ... with about a 50% chance of success.  I snapped a steel bolt off in the aluminum intake plenum on my car, and wanted a MUCH higher probability of success than 50% ... more like 100%.  So I looked for something different, a new and improved screw extractor.  These were different so I decided to give them a try.

What I liked most was the shape of the extractor end.  A normal screw extractor is highly tapered.  That requires a lot of force downward to get it to engage, and also causes a lot of force outward, jamming the bolt even tighter.  To me that has always been the reason these old-style extractors are so-so.  These are more vertical, which should cause less force outward and downward and more directed at rotating the bolt out.

The drill end worked, sort of.  It didn't have a tendancy to wander, but it also wasn't very agressive.  I followed the directions - very low RPM and reverse direction in the drill.  It drilled, slowly, very slowly.  After a while, I helped it a little by drilling with a smaller conventional drill and then drilling with the "power extractor" bit.  That worked well.  I finally had the hole drilled to the proper depth, as indicated by the "power extractor" bit.  I mounted the bit in my drill with the extractor end ready for business and pressed it lightly in the hole.  To my surprise, the broken end of the bolt came out easily.  The 6 mm bolt had been tightened with a torque wrench set at 15 lb-ft, so I expected some difficulty.

I rated the extracting end a full five stars and the drilling end maybe 2-1/2 stars, but overall I gave it four stars because the extractor worked so well.

I ordered them online. It came in and the container was about 2". I thought there had been a mistake as the packaging read MICRO. They were tiny. I don't recall seeing the word MICRO anywhere on the webpage. Had I been in the store, I would NOT have gotten these. I had a bolt that sheared off and needed out so I grabbed the largest one (did I mention they were MICRO) and the drill bit end wouldn't cut into it. So, I grabbed a drill bit of the same size and created my hole. I swapped it with the easy-out end, put the drill in reverse, and SNAP. The end of the easy out is now buried into my bolt that was in the hole. I don't have anything that can drill into the hardened steel. So, after about hour of under my truck trying to get the extractor extracted, I gave up and it's not coming out. I need to get a new yoke for my rear differential as one of the bolt holes has a broken bolt and a broken extractor in it. I JUST learned that that there is no warranty. I more than a lil upset about that. I'm going to call and learn what I can as I didn't know they were MICRO. Bottom line is, if you have small, weak screws/bolts to remove that are easily accessible, then these are for you. If you have ANYTHING else, these are going to leave you worse than before.

Had stud and was useless, drilled into material only to have the extractor break off, tried two different sizes and same results. Brought back to store and told it is a drill bit and has NO Warranty - no exchanges.
