Default EZ out/bolt extractors

Needing to extract broken brass gauge stem from flowmeter. Have these types of EZ outs which I've not had much success in brass with. Looking for recommendations.
Tried to upload flowmeter pic but recon since I already put it in welding forum I can't here?

I vote Neither!! I have removed hundreds of broken bolts and the only time I have ever gotten one to work was when the bolt was already loose. All they seem to do is smash the threads in tighter and make it harder to tap out in the end. You have an advantage with your situation because you are removing a pipe and have a centered hole to work with. Drill out (with a left hand bit if possible) there is a chance that the bit will grab the broken pipe and turn it out. Then chase the treads with a tap.

You might want to try an internal pipe wrench. I have a 4 piece set made by General that has 3/8", 1/2", 3/4" & 1" pipe sizes. Insert the size for closest fit and turn the end of the wrench with a wrench or socket. As it turns a serrated piece grips the inside of the pipe and hopefully turns it!

Use the square one tap it in firmly and use a T handle or 2 creasant wrenches opposed to one another for a even pull it should come right out. It works for me.

When removing broken bolt or pipe I use a Dremel with a carbide burr, square the hole, use the square EZ out. Once the hole is square, the EZ out bites without much expansion.

I've used both types of extractors with good results most of the time, most.....

I've had much better luck with the square ones. being a pipe fitting it would be very easy to drill it out too.

I recently bought a set of left handed bits and I'm hoping I never need to use them

Never seen an EZ Out do what it was supposed to, they always make it EZ to call up a foundry and get a casting remade.

One of the machine shop tricks we use is to take a worn-out carbide end mill and run it backwards on the stuck fitting until it seizes in place. The torque of the mill pulling on it breaks the stuck fitting loose no problem.

Go to a good plumbing supply house and get a pipe extractor. These have 4 or 5 straight knife edged flutes that engage the inside of the pipe without expanding it like an easy out would. You can get a set from 1/8 to 1/2" IPS for about $25 - well worth it if you use a lot of brass! If you know a boiler repair shop near you, they might loan you the tool, if you can bring the item to their shop.

EZ-out: One of the oldest scams around. NEVER seen one actually get a broken stud or screw out.

I do some broken stud removing and spark eroding. I usually make a very good $ when someone brings in a cylinder head that had an easily removed broken stud but they just had to use the ezyout and they've broken it off.

Broken steel stud or bolt if broken off level or close to it get a piece of flat bar a few inches to a foot long and drill a hole in one end about the diameter of the stud and sit the hole over the stud and arc weld the bar to the broken stud then tap the other end of the bar with sharp small blows with a light engineering hammer and wind the stud out, the heat also loosens old corrosion.

Internal pipe wrench would be great if I had a 1/8' but they seem REAL scarce. Think least I got is 1/4". Don't have much depth, safety on other side. JB's suggestion sounds like a good shot. Never had one of either that'd hold in brass. They'd just chew off the brass. Drill bits that'd taper holes on the EZ out angle is something I've oft wished for too.

Hi

I've tried all types of tap extractor over the years. Most effective is the fluted type extractor by a country mile.

One of the best investments you can make is a good second hand Snap-on/Blue Point tap extractor set:

Hope this helps, Roger

Thanx, Roger. Think you'd be right. Hmm, the "thanks" button isn't up, and the thanks I posted to the respondents since Ray don't either. Odd!

Being in the trades I agree with Andrew Mackey. I have had great success. Brass normally breaks free pretty easy. In the trades we call them nipple extractors. Good luck

I had a set of those snap on extractors.
Totally useless and I traded the set in for something else.

Tte depth of the splines often let them slip within hole.
