Amazing new stud extractor
46 studs out on 40 minutes. Only broke 2 & maybe could have avoided. 2 months ago they all felt like they would break. Soaked with Howes penetrant. Purchased this cheap $16 stud extractor off eBay $16 that you can use an impact on. Used my powerful Mac impact. I had to bore center of extractor all way through with 1/2 endmill as it’s hard. What amazing results.

Re: Amazing new stud extractor
I have one like that and decided I didn't like it. I didn't like the way it is hard to detect when a stud is going to break. The part you turn keeps moving and it is hard to tell if it is the stud or the tool moving.
I didn't use an impact with mine, though. Maybe that makes a difference. Mart. |

Re: Amazing new stud extractor
Hey Tony - what do you mean you had to bore the center all the way through? What is that all about?

Re: Amazing new stud extractor
It has a 3/8 drive square as well as the 15/16 external hex. I wanted it to grip at the base of stud as close to the deck as possible so I bored the center out with an end mill ( it’s hard). Now it drops all way down on stud. As well as impact I used a 1 7/16!wrench briefly on outer housing. Probably not needed with impact as once it starts to grip it keeps tightening its grip. It never slipped.

Re: Amazing new stud extractor
I think mine was the 1/2" drive version - it fits over without needing modification.

Re: Amazing new stud extractor
Kiwi, any chance you could video that process? I tried it and made a real mess. But I have no oxy cutting experience.
If you do film it on your phone hold it sideways. It makes a big difference to viewing. Mart. |

Re: Amazing new stud extractor
What does the inside look like? Jaws like a drill chuck? Does it mark the threads, are the threads reuseable afterward?

I'm glad to hear you had success with this unit. My buddy, who is a Snap On dealer, gave me one as well and he sells it on his truck. I did not have as good of luck as you did. At times, it would over clamp and I would have to take a breaker bar to break it free. The studs I was using it on gave me the fight of my life, so that could have something to do it as well. I still have it and will try it again on another project. Tim |

Re: Amazing new stud extractor
Thanks Craig. I have a full set of that style extractor unfortunately you cannot use an impact on them. I believe the impact is the key to this new extractor working so well. After close to 50 years of messing with these classic old engines along with many others, I have tried most every penetrating fluid concoction and every imaginable way of removing broken studs. For me I have narrowed it down to Howes penetrant & a drill & gas torch for broken studs. Quick & easy with zero issues. Thanks for your input.

Hi Mart; I was laughing out loud when I read this, thanks, Craig.

Use gas cutting torch have it set just like you going to cut 1/4inch thick steel. Drill 1/8th hole all way through broken stud in block. Now take gas torch heat broken stud until it’s very red then pull lever & blow molten metal through into water jacket. Careful blow all of remaining stud out. You will see it does not even heat threads in block up. Clean hole with “real” thread chaser. I have seen way more heat put into block& threads by people trying to free studs. Good luck.

Re: Amazing new stud extractor
The one being discussed here, is a chuck type. It's like a self tightening chuck that only works in the undoing direction.
The roller type is a different type. I have a roller one here that is for 5/16 studs. It was used at the factory for putting studs in the A series mini engines. Mart. |

Oooh Mart why did you have to remind me of your wonderful British motor cars. Like most every thing on the minis to change a lower radiator hose is pure fun. I worked on all those Austin’s & Morris creations in the early 70’s from minis to big dump trucks. An the same garage I also maintained a fleet of 41-47 Ford US pickups. Quite diverse. |

Re: Amazing new stud extractor
Bringing this back up, as I purchased one of these back in 2021 when this came up the first time. I finally had a chance to use it yesterday, as I needed to pull the short studs on a 59A in order to put tall Edelbrock heads on. I was able to pull the lower studs, plus 3 for an offset generator mount in about 30 minutes, and no broken studs. I was very impressed. Thanks for the recommendation.

I agree. This tool and the heat induction tools (like the Bolt Buster) are game changers for us in the old car hobby. |

Re: Amazing new stud extractor
Looks like a good tool, almost looks like the extractor that has the sprag bearing design.

Re: Amazing new stud extractor
There are some stern warnings about using the heat induction tool near a pacemaker and other bits of metal in the body. I would think that stainless implants would be safe.

Re: Amazing new stud extractor
I removed the studs from my ‘36 LB today and the first 41 came out no problem, but that last one decided to break. Why does it seem like it’s always the last one that gives us problems… or is it just me?

Re: Amazing new stud extractor
Nah, I removed the studs from my 37 21 stud engine, the first 40 came out okay, but #41 got me. I was able to finally get the remainder out recently. I should have followed my son’s advice, “let the machine shop remove it.”
If I had to do it over again, I would go right to welding a large flat washer and a nut on the broken stud. Last edited by Zeke3; 01-16-2023 at 12:33 PM. Reason: Added pictures and last suggestion. |

Re: Amazing new stud extractor
It looks like a collet type. My old Snap On set is a bit longer to give a good taper length to the collets. I've pulled and installed many a stud successfully with that set. The old Snappy stuff came in metal boxes. I don't know if they still make them or not.
