Product Description
NEIKO 01925A Left Hand Bit and Easy Out Extractor Set. Remove broken screws whether working on wood or metal, ideal for construction, automotive or home DIY projects. Left hand drill bits prevent you tightening the bolt you are trying to remove while creating a whole to put the extractor in. In some cases the left hand drill bit will possibly remove the bolt or screw without needing the spiral flute.
Step 1: Wear the proper safety gear such as safety glasses and gloves.
Step 2: If necessary use a center punch to create a indentation in the center of your broken fastener.
Step 3: Select a left handed drill bit that has a smaller diameter than your stuck fastener.
Step 4: Carefully drill down aligned straight with the screw about 1/8th to 1/4 inch.
Step 5: Insert the tip of your screw extractor (spiral flute), turn the tool counterclockwise. As you turn the extractor while forcing in the threads will grip or bite into the hole, continue turning counterclockwise and pull to completely remove the stripped or broken screw.

There was a problem filtering reviews right now. Please try again later.
One that often gets overlooked is using a left hand drill bit. Since most bolts are right-hand thread, drilling with a left-hand bit does two things at once: It weakens the bolt which reduces the pressure on the outside holding it in place, and it provides a twisting force in the direction that unscrews the bolt.
Often this is enough to get the bolt out by itself. If not, you either keep drilling or you use a screw extractor in the hole you just created. Very rarely do I have to go any further.
This set of bits will handle small and medium-sized bolts and screws, and it does so well. The bits themselves have a tendency to get dull but they're not difficult to resharpen. Since I only drag them out when I break a bolt, they don't get a lot of use and thus last a long time.
Would they survive in a machine shop? Maybe not. The metal is fairly soft and it doesn't take much to chowder up the cutting lips. But they've been in my home shop for 10 years and are still going strong. I use them sparingly, but when I need them they usually solve the problem quickly.

Ok so I had a very badly stripped differential fill Allen plug. Standard plug on a Land Rober SUV. This was semi stripped by prior mechanic and I just made it worse without the right tools. Tried the cold chisel method (you can see from photos I whacked the s&@t out of it and no luck. Bought the other stripped allen key versions on Amazon (the ones that have a slight twist in a standard looking hex/Allen to provide grip) and they just won’t get enough grip (not even close in my case so a big waste of time) if you were as badly stripped out as I was. No chance at all. I was really thinking I would need to learn to weld and go buy a welder to attach another bolt on which was going to be my last resort…
Tried this and worked extremely well (was done in 20 minutes) with the following comments:
As you can see from the photo I used the 11/32 size which fit about a third of the way into the stripped hex differential plug loose. I tap tapped it in gently with a 3 lb hammer to get it about 2/3 of the way in. You don’t need to be poinding it in hard since these have a slight taper which makes them slightly larger as they go further in. As you can see after massively torquing it at the end while successfully remove the fill plug it was ultimately seated about. 90% down. With the large 15mm sized head you know have a solid place to add a socket with a breaker or heavy duty impact.
Other comments - IMO very little chance of this snapping off as I see others concerned about - I can’t attest to the quality of the metal but the size I was able to use makes it less likely it would snap. If I were to use the smallest 5-6 (9/32 or less) of the extractors provided I would be more concerned about putting a long breaker bar but at this size no issues. I ended up having to put a 15mm socket on a two foot breaker bar / pipe to get this to finally come loose. And once it did it was literally just finger screwing the rest of it off. Amazing how a seized bolt will hold until it doesn’t. I tried my 3/8 inch (air) impact gun before the breaker bar which is a low clearance since I didn’t have a ton of space. It’s like 350 foot pounds of torque so a mid range impact and it didn’t budge this differential plug although it MAY have weakened it up a bit so my breaker bar worked easier.
Best of luck of luck to those reading this but this is the best of 3-4 methods I used and wish I started here since it was easy.
Last bit of advice don’t underestimate how much torque you need to get one of these seized plugs off! And if you are in a tight area and able to use one of the provided extractors with some reasonable girth a long breaker bar is the way to go…

In my case, it was valuable to soak my bolt with penetrating spray and allowing it to soak. I used a steel punch to pilot for my drilling. Cutting fluid was applied to the left handed drill bit and I operated my drill at very slow speed. I was pleasantly surprised to see that the Neiko bit immediately had a good bite on the bolt. It removed a couple millimeters of steel, and my bolt began unwinding.
highly recommended.
