OK people, after reading through some of the comments...... The purpose of this video was to show another method that CAN BE USED when a Cutoff tool or large bolt cutters are unavailable. The average person cannot pick locks, so that wasn't even a factor. The lock used in this video(which had a 3/8" diameter shackle) was 100% irrelevant. I was simply showing what to do on any padlock I had laying around. Normally this would be used on padlocks that are higher quality, and very hard to pick. This method can also be used to cut hardened steel bolts or rods, and as mentioned in the video, allow you to drill through hardened steel plate. If another channel uploaded this, or stole my idea(which has been done before), their video would already have 1/2 million views and everyone would be praising the video. To top it off, many TH-cam channels don't even talk to viewers in their videos or explain anything in detail the way I do on my channel.
I've used this technique to cut hardened chain before, used fire bricks to make a sort of heat chamber like a crucible, heated up 1/2" tempered steel enough to anneal for cutting. Also if you get steel hot enough so it's glowing yellow/orange then rapidly cool with iced water it's overly tempered and brittle and can break with a cold chisel impact.
I have a seized axle that I'm replacing on the bottom bracket of my bicycle, and I will be trying this tomorrow to soften the steel for cutting. Thank you for the great video! A torch is also great for expanding crank arms for removal if you don't have an extractor tool.
Thanks for speaking clearly so that I can play this video at 4 times the speed and understand you to make this play under 2 minutes. :) Another method for those locks it to take a heavy hammer and give it a good hit on the side to open it even faster, which is what locksmiths do.
Locked my keys in the garage but luckily the blow torch was in the garden shed. Tried this with an identical padlock and it worked really well! Thanks for posting. For those who think you might burn the building down, if you aim the flame well, the door paint only gets warm to the touch and certainly does not peel or scorch.
I tested this at work with some circular stock made out of hardened tool steel. I heated a 3/8" diameter pin to around 2200F and used a steel hammer and chisel to drive through it. Also heated another and quenched it with water. I could then use a file to cut through it. To cut through a hardened lock, you can also use a cut off wheel (fastest method) or a carbide rod saw if the shackle is too thick to cut with a large bolt cutter.
Interesting video. I thought about this the other day when I needed to force a lock. I have 4 kids and thirsty friends so it happens surprisingly often lol. Normally I use an angle grinder but I was thinking about a more discrete and pocketable approach using a leatherman surge with a hacksaw blade attachment and a torch lighter. I think I might give up on that idea because it obviously takes quite high output to normalize the steel.
If you heat a shackle to bright orange, even going on to white hot, a set of bolt cutters will slice through that section of the shackle with ease (not quite literally 'knife through butter' ease, but close) and without doing damage to the high-carbon hardened steel bolt cutter blades (which just about always results to the uniform cutting edges of bolt cutter blades, when cold, hardened, high-carbon steel tries to cut/snap through like [or even harder] cold, hardened, high carbon steel). ...and even a much smaller set of bolt cutters will do the job.
You're welcome Dan! Be sure to look over my extensive video playlists for other great videos of interest to you, and most importantly share my channel with many others. Thank you
Good to know but i very much doubt that the cheap lock was hardened, even if its stamped on it. The hacksaw not gripping would most likely just be the chrome plating, give it a few more goes with the hacksaw. Lean the hacksaw against the body of the lock to keep it stable and give some hard strokes of the hacksaw. Obviously raking or picking that lock would be super easy but you explained what and why you were doing it.👍
I feel like I just sat in on a lecture that's part of the curriculum towards getting a doctorate in B & E, hahaha. That was also meant in *no way* as some sort of backhanded, passive-aggressive dig towards the topic of this video & never would in a million years either due to how I consider my ever-growing lexicon of exotic & creative ways to wreck havoc as the penultimate spice of my life since forever, heh. Worth noting that my ratio of things destroyed to things learned has a deficit of inaction by many orders of magnitude soooo *shrug*...

One of my lock keys broke because it was 10 degrees out and I needed in my storage unit. I have one key left and if that fails, I will be running to the store to buy a lock and doing this. Another option would be putting a carbide grit rod blade into hacksaw and cutting with that. You might bypass the preheat step with that.
Wish I had seen this years ago, many years, too many years. I had a giant pair of bolt cutters and a friend of my wife needed a large lock cut off of a storage shed. The bolt cutters cut the lock off and also chipped the cutter blades.
Hi Ethan. This will work on all hardened steel shackles. Be sure to watch and share my "Locksmith/Bypass Tools" video playlist below. Thanks for watching! th-cam.com/video/ErpS7C4gUVA/w-d-xo.html
I find it easier to use hamer and break shack if suitable. If that is not possible,a cordless drill does job really well. This method is for bigger locks,it was overkill for such small lock. But great video,very informative. Maybe try thermal shock next time. P.S. People normalise ball bearing housings amd make knife with them,and i remember those breaking like glass if you hit them with hammer or drop them.My coworker has piece of metal stuck in his hand,now he knows that putting tempered steel under hydraulic press is not smart.
That's because the high-carbon steel article had been uniformly hardened ALL the way through. Things like shackles are 'case' hardened on the outside to some depth, but retain some tensility at the core to prevent shattering from percussive force. During my many years boilermaking/welding, and steel fabricating in engineering shops, we often worked with hard-faced steel plate (which has been surface/face [case] hardened surface to a depth) and where the drawing required holes to be drilled, we'd always pre-heat the drill-hole site around the center-pop mark with the oxy torch to soften (anneal) the surface at that point before drilling - otherwise it just takes a big toll on your drill bits, and magnetic drill bits.
generally the padlock will be in use with a `Hasp and Staple` and all the components would be in close proximity to a door or gate making the use of a Hack-saw unpractical, if you have softened the metal then use your bolt cutters.
Using a hack saw to cut the lock on a hasp shouldn't be any problem at all. You usually have plenty of room. The padlock can be rotated into a position which makes it easy to hold and cut. I do like your idea of saving the cutting jaws on bolt cutters.
You would have to heat it to a much higher temperature than we can get like this. Actually you would have to melt the shackle or turn it into gas and I don't even know how hot it would have to be...
Yes, but the average person doesn't know how to pick locks like you or I. If you have a cheapo propane torch and hacksaw laying around, It's easier to do what I show.
I consider using a rake as one method of picking (as opposed to manipulating the pins individually). And I am a novice at it so I may be wrong in my terminology.
Somewhat faster method: Homemade shaped charge explosive! It sonds like a firecracker if you cover it with sand bag, and that blocks the light flash too. Not too stealthy... Ok, more "down to ground" thing...thermite or die grinder and one HEAVY backpack of lead acids. Do not try it at home, leave it to the stupid ;-)
Sure, If you have a cordless unit, but what a smart person would say is, " Thanks for this video(which I didn't have to share), this is great information to know in the event I don't have a Dremel or large enough bolt cutters". I keep track of the good and bad on my channel. The bad will never get any assistance from me if they ask for it.
electronicsNmore My bad for the language. I am sorry. What I wanted to say is that the method takes too long, not the video. A thief wouldn't waste 7 minutes but I promice you that without picking, but with a crowbar or a hammer or some power tools that lock doesn't stand 1 minute.

normalizing the metal makes it softer therefore easier to cut. Good thumbs up worthy tip. Thank you for sharing.

Got the lock off but burned the house down.
Don Nelson Good one
Hilarious
True
Burned the house down and STILL didn't get the lock off.
Very good video and it sure helped me get a padlock that I had lost the key to. You're right... I couldn't pick the lock and this was a lot easier.
Please share. Thanks!
Amazing - never knew you could reverse the 'hardening' effect by heating the metal up again.
Many thanks !
Heat it up until its red or light orange and cut it with a bolt cutter.
@James Sempy
It's not that simple.
@@rfi-cryptolab4251 exactly why wait for it to cool. It's way easier to cut and saw when it's hot

To cut through a hardened lock, you can also use a cut off wheel (fastest method) or a carbide rod saw if the shackle is too thick to cut with a large bolt cutter.
...and if you heat the metal up again to your crucial temperature, and drop it straight into cold water (or oil) then you will harden it again.
Carbide hacksaw blades can come in handy for these kind of jobs .
Not really necessary for this job. The steel is really easy to cut after the case hardening has been undone. Thanks for watching!
Just buy a cheap pair of 18" bolt cutters for cheap locks like that.
For bigger locks a cut off wheel or carbide rod saw work good.

what kind of hacksaw blade do i need to cut boron carbide?
After heating, you can use a bi-metal hacksaw blade with 18tpi.
Great content. Keep it up!
Thanks for the video. I tried to torch the shackle and after a while, the shackle just fall apart from the padlock body! Anyway, heat does the job.

Nicely done video. Thanks.
Could u cut it with bolt cutters at this point?
Yes, it would cut very easily.
What if you just cut the Lock when its glowing Red Hot?
It would cut easy, but the heat may destroy the temper of the hardened cutting edges. Thanks for watching!
HEY PHILL SWIFT HERE
WE SAWED THIS LOCK IN HALF
NEXT WELL FIX IT ONLY WITH FLEX TAPE
I like this idea. One more way to defeat a lock that malfunctions on me or another key gets lost to a cheap lock.

You can try sliding a bunch of steel fender washers over the shackle before closing the padlock. :-) Don't forget to rate thumbs up and share. Thanks!

Good for slow burglarizing for quicker burglary use bolt cutters
Good for larger padlocks where a bolt cutter won't open wide enough.

@@electronicsNmore i have spent more time on your Channel than with my mother 😂
Why would anybody wait until the Lock cools just to brake it.
If you think you can easily break that shackle when it's red hot, you're wrong.
You would have to heat it to a much higher temperature than we can get like this. Actually you would have to melt the shackle or turn it into gas and I don't even know how hot it would have to be...
First, I would try picking the lock. It's not that hard on most padlocks (the one you're showing looks like a Master).
Yes, but the average person doesn't know how to pick locks like you or I. If you have a cheapo propane torch and hacksaw laying around, It's easier to do what I show.
mediaguardian It's a Master lock, no actual picking required just a quick rake. And sometimes a stern talking to works.
I consider using a rake as one method of picking (as opposed to manipulating the pins individually). And I am a novice at it so I may be wrong in my terminology.
disgruntled181 Only works with the cheapest locks. Even just modest master locks have some security pins.
Cool science but when it's on a bolt on your shed door this would be awkward, 2 spanner trick for me

ali.070 try I have an ethical alternative for you: buy your own bike.
poor flame...shoulda heated up a lot faster than that😒
It takes time, especially since the shackle was 3/8" thick.
🙏
So you don't have bolt cutters, but for some reason you do have a propane torch... what?
Thethirdman 703 What exactly does that have to do with the purpose of this video? LOL
I just pull out my gas cut off saw unless it's in the building with that lock that needs cutting off then im SOL until now!
