Anyone know what these are?

They were in a tool box I bought awhile back along with a gasket punch set. That's a standard size razor blade for size reference.

Pipe thread extractors. Removes male threaded pipe pieces from fittings.

They're internal pipe wrenches, or extractors for removing short section of pipe when you can't get a wrench on the outside.

Yup, internal pipe wrenches
Good for use on pipes with show, Crome, or polished finishes.
Aso good for very short (close) pipe ******* where there is no place to grab

Looks like you have a set of 3/4, 1/2 and either 1/4 or 3/8; nice to have when you need them for a plumbing project.

I have a set in my truck, however I've never been sucessful when

it comes to using them. For some reason, the darned things slip

around in the pipe rather than really grab the broken off pipe to be

extracted. Perhaps different makers adhere to different standards ?

I still have them in the truck, but I have all but given up trying to

use them.

Yeah I found about 10 years ago most of the pipe started getting slightly thinner walls and they didn't work right anymore.

Slip a shim inside with the tool and tighten them up...

i'm no plumber, but I've got a couple.
the only thing I've used 'em for(w/ mixed results) is getting rusty/stuck seat posts out of bicycles

Just curious, if you have used an internal pipe wrench AND a flute screw extractor before, which one does a better job of removing a 1/2" broken pipe?

I want to buy one quality set for my toolbox and because it's seldom used I don't think I want both. I'm leaning towards the flute screw extractor because it can double as a regular screw extractor so it's probably more useful. What do you think?
