Review: Reversed a stuck bolt out of the engine block. - This worked like magic. I was skeptical at first and even after I drilled through the remains of the snapped bolt. I took my time to slowly drill through the bolt with a smaller bit. After I got through, I switched over to the next size up. It started to drill slowly then eventually got caught. Once it got caught, I started to drill in slow bursts which eventually freed the bolt from the engine block. It quickly unbolted after that.
Review: Got me out of a jam--recommended - I do most of my auto repair by myself––age 73, so no novice, but not a pro by any means. I had broken off two of the five valve cover bolts on my '02 Honda Accord while tightening down. (Watched too many videos on the subject and tried to use my 1/2-inch torque wrench, which just wasn't made for a light 7 foot-lb. setting. Next time, it's back to the old "feel" method.) These are 6 mm (just under 1/4-inch) bolts that have a flange on them that prevents tightening them down too deep into the aluminum head. So I suspected they were not jammed into the threads. They should come out easy if I could get a drill into the bolt center and reverse thread out. I tried my set of Grabit brand easy-outs, but it just made a mess of things. You set your drill on reverse and use one end to drill a pilot hole (they call it "burnishing"). Then you flip the bit over and use the other, reverse-threaded end to try to grab the bolt and screw it out. I tried the #1 and #2 Grabit bits, but no go. I suspect these are only good for soft metal, because I spent nearly an hour drilling and very little metal was removed. They just left a rounded depression in the top of the broken bolt. Their promotional videos always show it being used on wood screws, which are softer than automotive bolts. I switched to a nice set of titanium drill bits that I reserve for metal, no wood--trying 7/64, 1/8, 9/64, 5/32, and 11/64. Nothing would remove much steel. I haven't used this set much at all, so could not believe that every bit was dull. I began to suspect the bolts were made of a hardened steel, and might require carbide bits. Called a mechanic friend who told me he wouldn't do it, but knew a shop that could weld on a small nut and take it out. (Visions of big bucks began dancing in my head.) But he also said his brother had just used reverse drill bits to solve a problem on his motor cycle. Figured I'd give it a try, and almost drove down the local AutoZone to buy their set of 5 reverse bits for $9.99. Then saw that desertcart had this set of 13 reverse bits for only 3 bucks more, and I've had good luck with some Neiko products. So I waited the two days for Prime delivery, and so glad I did. Right away, I noticed the Neiko 1/8" reverse bit was really removing some metal. I had to also try 9/64 and 5/32 before it grabbed into the chewed up bolt head, and easily turned it out. The second bolt which I hadn't bolloxed up with a Grabit and other drill bits, just wound right out on the first try. Boy was I happy. Problem solved. This method should work for the rare bolt that has broken off this way, not because the thread is frozen or welded in there like you find on exhaust manifolds and other places--that's a whole other story. But for a small bolt that broke off the way mine did, I swear by this product.

May break easily at high speed when drilling out broken screws. Slow down and use a lubricant.
