SIXGOD 5 Pieces Easy Out Bolt Extractor Set, Straight Fluted Screw Extractor, Broken Damaged Bolt Removal Tool Square Type

Used one for the first time the other day. Did what is supposed to do. Not a big or overly tight bolt so it was easy enough.

Every broken fastener is different. That's why you need a variety of different extractors to get them out. As a rule extractors of any design are hard and brittle and prone to breaking, that's life. So far this style of extractor is my preference for the majority of broken fasteners. These work very good in my opinion.

Awesome got it and used it working 10 min to remove a stubborn stripped oil galley plug AWESOME !!!!!

I had a lot of hope with these extractors. With a good variety of sizes, they can cover many scenarios. The straight-tapered extractors (with fairly sharp flutes) are good for more sensitive bolt extraction where the risk of expanding the bolt (or glow plug body!) would result in seizing. Unfortunately for me, the first size extractor was a bit too big and failed to stay engaged. The next size down required more drilling out (of the glow plug). This allowed a deeper engagement, but at the cost of increased seizure risk. I made the mistake of placing the wrench at the end rather than close to the glow plug. The result was a snapped extractor 🤬. For some time now I’ve been in recovery mode trying to extract the extractor—the carbide material is strong but brittle and requires diamond burr abrasion, which is a slow process. Unfortunately, this has not been a time saver.

They work nicely but they are very brittle.. broke one the first time I used them.
