Reverse drill bits
I love these bits. They don't always work for getting snapped bolts out but when they do its very satisfying. Prob a 60% success rate with them.

My muck grab had two grease nipples crushed when it was crowded back fully open on a different machine to mine and obviously the geometry didnt work as along with the nipple damage a.hose end was crushed too!

Anyway, hose was fixed straight away as.machine was needed. Grease nipples and extracting the snapped off section I have put off for a while, expecting it to take ages. In the end, about 3mins to do both and another min to wind each new nipple back in.

Gotta love those reverse bits. Never had two successful wind outs in one sitting. Cheers

They are good to be fair - on occasions as you say.

Can’t help thinking they sound like they should be in the same category as glass hammers, long weights, and elbow grease though 🤪

Is this the same idea as an extractor set?

Yes and no ref extractor.

Granted an extractor in hollow grease nipple would of done it if i had one small enough.

Usually the bolt needs drills for an extractor stud kit.

Drill.it with a left handed drill bit and jump a size after pilot hole and it it may bite and unscrew it for you. Is also not trying to tighten the bolt as you drill it. Cheers

Interesting. I bought a couple of sets of these once upon a time, and I can't say I've found them to be as useful as that. I certainly wouldn't say it was a 60% success rate.

I think they had a Sealey label on them, but maybe they're just not good enough quality. Donald
