- Removing a broken bolt or stud can be extremely difficult but in some cases such as when the bolt head has been sheared off by sideways force it is possible to remove the remainder of the bolt using a left handed drill bit. Here we demonstrate how to remove a broken stud using the left handed drill bit method.
Show me with a rusted bolt that's totally inaccessible up in the rear frame of my land cruiser...
The first method shown was spot on and saved me hundreds of pounds, after overtightening an M6 fastener that snapped on my egr valve. thanks
This is the best video I've ever seen on this method. Thank you!
These are great! They've worked every time I've used them.
Thank you!!! Bought a rifle with a broken stud in the rear sight!!! You saved me the fee to have the gunsmith do it! Thank you! Thank you!
Thanks for posting. This explains everything with great detail. Looks like separate bits and center punch is the way to go.
I Snapped A Spindle On My BMX, This Video Is Awesome, And I'm Blessed To Say That My Broken Bolt Is Leveled With The Entrance Of The Crank.
Brilliant! Thank you for the upload, I for one appreciate it. Cheers.
I just unscrew an m5x16mm mtb cleat bolt using this method. Thank you for sharing this. It really worked!!!
or use gradually larger bolts to thin out the walls of the bolt so eventually it can be removed in pieces. i do appreciate your videos. sending this one especially to an australian friend of mine. who has a broken exhaust bolt on a motorcycle he needs to remove
Gr8 Vid , never heard of a left hand drill bit . Thanks for sharing .
Wow I never knew they made left handed drill bits, I use a similar tecnique with a right hand bit, but with a left hand bit a could double my productivity, thanks for the vid
I used to work in the toolroom at a plastic injection molding facility. Removing broken hardware is a huge part of the job. By far the worse thing to remove from a blind hole is a broken dowel pin. I was just going to say that you can get easy-outs in sets. They have the appropriate size left-hand drill with them. Most often, the broken stud comes out with the drill and you don't even need the easy-out.
Great video. I broke a exhaust manifold stud off in the head of my 03' F150 and it was hell trying to find LH drill bits! Finally found a 13 piece set at Harbor Freight. I'm going to give it a shot this weekend.
Thank you, thank you SO much for all your videos, especially this one. I have just removed a small bolt completely sheared off, by following your video. I have all the tools, I just needed your guidance. Please don't give up your video's, they're a God send and I can't thank you enough! 📏🪥🔨🪚🪛🛠️😊
done many stud extractions but never knew left handed drill bits existed! thanks!
I'm impressed. I thought you were just gonna drill it out but this way is safer. I hadn't even thought of this.
So I see some doubters here, I've been doing marine and industrial repair and maintenance for close to 40 years now and I have a set of extractors and Left Hand cobalt bits in my box. They've saved a lot of work, and made a lot of believers. Drilling the bolt relieves the stress using the LH bit means all of the torque is trying to twist the bolt out and gives you a head start on the easy-out. And yes it works on rusty and bi-metallic corrosion and if you're lucky even on galled SS. Don't count on the last.
Love youre accent man, great vids!
