In a recent SMA video https://www.youtube.com/watch?v=C66C3_pqqz8 I removed a broken brake bleeder. In the comment section of that video a lot of you asked what kind of broken bolt extractors I used. So much so that i could not answer all of them! So by popular demand here is a video showing you a few of my extraction devices I use. I highlight some of the features I like and dislike about each kind. I also show some of the drills and drill bits I like to use.

    Thanks for the video, but the link is broken.

  2. Avataaar/Circle Created with python_avatars SWTWHITEGSR says:

    I had one break in the hole it was a horrible experience itโ€™s a strong material couldnโ€™t drill it out.

  3. Avataaar/Circle Created with python_avatars Johnny Sechrist says:

    Bought those Snap On fluted ones back in the 70's….work great. Glad I had kin in snap on corporate.

  4. Avataaar/Circle Created with python_avatars Ronald Johnson says:

    What? No "turbo" sockets for rounded bolts/nuts?

  5. Avataaar/Circle Created with python_avatars Travis says:

    yea its nice to trade them in, but what do u do with the car on ur only lift thats half apart stuck up there till the snap on guy decides to cruise thru? its just easy to avoid heating it

  6. Avataaar/Circle Created with python_avatars Jeff Leblanc says:

    I got to broken bolts on my starter the 3rd bolt backed out causing the bolts to break of i guess a lot of 6.5 s have had this problem I think Iโ€™m going to order the ridged cause you get guides and ther straight fluted if they donโ€™t work I will go to the snap on style on a 6.5 thers almost a half inch or more were ther is no threads so I really need something with guild at least to drill Iโ€™ll buy a set of left hand bits they are not rusted or anything and I didnโ€™t torque them wen I put starter on so hopefully it will work most of the easy outs they sell around here in canadian tire are sort of crappy ther way to short good video

    Excellent video thank you ! Had an npt steel plug sit very tight in a cylinder head and stripped it out (was a hex) I think due to the high temp thread sealant on there. Waited several days now gathering up info on how to proceed. I settled on two different sets of the straight flutes and your vid and experience (which is obvious in hearing you talk ๐Ÿ™Œ๐Ÿผ) has made me confident Iโ€™ll be able to pull it out easily and that I chose the correct tools for the job. ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ

    You should have a center drill in your toolbox. They donโ€™t walk like the regular drill as they are stubby with a thick shank. They are also cheap. In aviation I used a 3/8โ€ socket to rivet gun, air hammer, adapter. It also has flats for a 5/8โ€ wrench. The hammering drives the Phillips or torx bit into the screw head and vibrates it. The wrench applies rotational force. Screws donโ€™t stand a chance.

  9. Avataaar/Circle Created with python_avatars Ronald Poddig says:

    The ones I have look like sockets with the flutes inside to grip the bolt.

  10. Avataaar/Circle Created with python_avatars Juan Alcantar says:

    Mayhew makes a square one that itโ€™s bad ass at removing spark plug that have seperated

  11. Avataaar/Circle Created with python_avatars dreddnott says:

    The Blue-Point (Ridgid) straight fluted extractor is definitely the best one. I used my dad's from the Snap-On truck growing up and recently ordered one of my own direct from Ridgid.

  12. Avataaar/Circle Created with python_avatars Steve B says:

    I was attempting to do a brake rotor replacement on my Hondoo ๐Ÿ˜ŠRidgeline
    following your wise tutorial on another video when the tip of this GearWrench
    impact driver I was using for the first time broke off in the head of the
    rotor retaining screw. How would you recommend removing that retaining screw
    now?

  13. Avataaar/Circle Created with python_avatars Patrick says:

    Very good! I owned an air conditioning and radiator shop for 30 years. Bolt together radiators with aluminum tanks were a nightmare. The steel bolts would seize up. I had Snap-On sets just as you showed. I also found the kit with the straight extractors worked better than the tapered extractors. We used heat when ever we could.

  14. Avataaar/Circle Created with python_avatars Graeme Diesel says:

    You keep costing me money, mr O. ๐Ÿ˜

    I already have a ridgid set identical to your blue point(which is excellent). Now i think i need that snap on set to complement it.

  15. Avataaar/Circle Created with python_avatars Cole B says:

    I got the snap-on 48-pc master extractor set, (Irwin made) simply because of the warranty service. The left-hand drill bits in that set are Irwin m42 8% cobalt bits, and a GODSEND for heat-hardened manifold bolts.

  16. Avataaar/Circle Created with python_avatars Cliff Perrino says:

    your the best! thanx for the info

  17. Avataaar/Circle Created with python_avatars Adam Brewer says:

    good stuff buddy, a wealth of knowledge!

  18. Avataaar/Circle Created with python_avatars 2009mechanic says:

    I have that exact set of Snap On Blue Point extractors.
    Just don't ever break one off , then you're screwed.
    I use the cheapo Harbor Freight torx bits in rounded out allen head screws and bolts.
    After about the 3rd time you just throw them away so I stock many of each size on those and they are cheap enough.

  19. Avataaar/Circle Created with python_avatars Eric Cagle says:

    Excellent video brother! Very informative! Subscribed!

  20. Avataaar/Circle Created with python_avatars Sounds Of Nature says:

    Good ol self made auto channel. My favorite mechanic.

  21. Avataaar/Circle Created with python_avatars Alessandro Terracciano says:

    I consider myself lucky so far I've done all the maintenance on my vehicle with a few tools

  22. Avataaar/Circle Created with python_avatars Russell Foote says:

    The set with one missing, short reverse spiral flute you think is Mac; I have the same thing but Snap On. Trying to remove exhaust flange bolt on 98 F-150 5.4L. I found they just shave out the drill hole and don't even bite in. I'm afraid to use a long extractor, that it will break. I also cant use the handle for the different sizes of square ends to turn, there's no room. I guess I'll have to drill it out and use a bolt and nut. If you even get to read this, most important is thanking you for all you have done to enable me to be able to drive rather than walk. On SS only. If I don't fix it, I'm walking. ($ drives, no $ walks.)

  23. Avataaar/Circle Created with python_avatars Jimmy Vickery says:

    I use torx bits a lot

  24. Avataaar/Circle Created with python_avatars James H says:

    I had a crank dampener bolt break inside of a 617 merc diesel, that bluepoint set got it right out. I was pretty impressed.

  25. Avataaar/Circle Created with python_avatars Andy M says:

    dont use the Torx extractors— if they break off in the hole, you've now got some hardened steel in there that you can't drill through… which is what I'm dealing with.

  26. Avataaar/Circle Created with python_avatars Matt Garza says:

    Does anyone have success with the box-wrench style extractors? It sorta looks like a ratcheting box end wrench, but it's actually a jagged/spiral design that supposedly grips onto the rounded bolt pretty well. I realize rounded bolts is a different subject, lol.

  27. Avataaar/Circle Created with python_avatars Russ Shaw says:

    Going to attempt an extraction on a 2000 dodge caravan with 2 bolts broke in the motor mount bracket. Any advice for deep extraction in a tight spot?

  28. Avataaar/Circle Created with python_avatars ryan s says:

    The torque bit idea is awesome

  29. Avataaar/Circle Created with python_avatars Brother Othni El says:

    You are the real deal blessing to you

  30. Avataaar/Circle Created with python_avatars Aaron Ledford says:

    Transfer punches work good for getting a punch mark in the center of a bolt that's broken off in a hole. Gives you a better chance of drilling in the center. I have used an end mill in a drill to make a flat surface on the broken bolt too.

  31. Avataaar/Circle Created with python_avatars IM MILLER says:

    Bolt extractors are still great and reliable though.

  32. Avataaar/Circle Created with python_avatars IM MILLER says:

    Great information, thank you, i watched because I was having limited success with the spiral fluted as well, hate screw extractors on any bolt less than 3/8 or 8mm in diameter. So time to seek a more reliable replacement version.

  33. Avataaar/Circle Created with python_avatars BetosGarage says:

    Back bolt driver side Ls 6.0 . I swapped it in my regal freshly wired brush cleaned and painted and I just noticed that dam bolt stuck flush in there . Luckily I can get a extension and reach it through the wheel well but no luck on removing . I scratched the head up a bit tryna drill a small hole to punch something in there to extract it . I was so frustrated called it night before I made it worse and now Iโ€™m here . I need a good extractor kit , Home Depot or harbor should have one right? I broke so many drill bits drillin a tiny hole on that bolt

  34. Avataaar/Circle Created with python_avatars White Hat says:

    Ya in front of snap on part number they donโ€™t make it..

  35. Avataaar/Circle Created with python_avatars Sigh Pocket says:

    Nice!!

  36. Avataaar/Circle Created with python_avatars Stephen Mcgraw says:

    It makes a big difference when you have proper tools Eric love your shop ๐Ÿ‘

  37. Avataaar/Circle Created with python_avatars keo janar says:

    How to remove the screw extractor if broke into hold of broken bolt?

  38. Avataaar/Circle Created with python_avatars Tom Christensen says:

    I have 3 sway bar bushing bracket bolts I need to drill and remove. this should be fun…

  39. Avataaar/Circle Created with python_avatars Donald Cary says:

    I wish you were in my town

  40. Avataaar/Circle Created with python_avatars faronf2006 says:

    Never knew about using a TORX style bit for extracting a bolt …good to know . Maybe the impact versions would be the better choice .

  41. Avataaar/Circle Created with python_avatars faronf2006 says:

    Wow …Great video , thanks for sharing . Always wonde what type of extractors work best for different applications .

  42. Avataaar/Circle Created with python_avatars neutered10mm says:

    I have an EFI 460 in an E350 van with 3 busted exhaust studs just below flush … fairly sure the heads are cast iron … would the welding method work since cast iron is so difficult to weld and shouldn't blend with the weld puddle inside the washer/nut/stud?

  43. Avataaar/Circle Created with python_avatars Salman Khan says:

    Thanks Bro๐Ÿ‘

  44. Avataaar/Circle Created with python_avatars Justin Paone says:

    the fluted kind are my favorite and i never see them any where for sale. but haven't looked in 20 years. i'll try amazon. the benefit to those is you grip the entire stud if you drill it all the way, where as the tapered not only expand like you said, they also are only gripping maybe an 1/8th of an inch and i always snap em off. i have a husky set like your mac set. got it from home depot and its for removing broken off threaded water/gas pipe. make sense rigid would make it since thats there history.

  45. Avataaar/Circle Created with python_avatars David Timmel says:

    Try the Craftsman "Professional" split point drill bit set, part #964086. Best bits for drilling metal I've ever used.

  46. Avataaar/Circle Created with python_avatars Donny Wilcox says:

    Just to be clear I was only asking if the heat did mess with the temper and I understand now because I use to work in a body shop and if one of my snap on or matco tools broke I just had it replaced …people who do not know trust me you pay enough to purchase the tool that they should fix or replace any broken tools ….so sorry if you thought I was trying to bash you or anything ….can't imagine the rust you must deal with ….I live in Tennessee …so not as bad here but still your information on removing broken fasteners …..very educational

  47. Avataaar/Circle Created with python_avatars GOINโ€™ HOT says:

    Torx for extractors saved my ass lol ๐Ÿ˜‚

  48. Avataaar/Circle Created with python_avatars ommy ber says:

    Grinding stone bit will grind down extractor and little chisels will work too.

  49. Avataaar/Circle Created with python_avatars Anthony GM85 says:

    Those muti splines are great for stripped out hex and Philips
