Dennis, I've used cold chisels for over 40 years and never thought about using them in this way until seeing your video. An old dog learns some new tricks. Thank you for sharing. :-)
Again absolutely great video. When it comes to tradistional means of moving material people tend to overlook the chisel completely. Thank you for making this video, as it demonstrates very clearly how effective these tools are, and even superior for certain tasks.
D F I'm 72 and very handy in my DIY experience, and you showed me a lot of I've been weading chisels because I wasn't taught much. I had a woodworking and steel shop in school, and them teacher actually more like babysitter than truly trying to teach. I believe teaching something about just keeping the parents on the jobsights and having kids not to hunt each other, yes, like babysitting and selecting a few kids who have great learning abilities to become brains to build this nation. Wish I had such as you as a mentor and influenced me. Thanks for the teaching
I have only used cold chisels on masonry or shearing rivets or splitting nuts. Never thought of using them in this manner. Thank-you for posting such an informative video. Cheers.
Many thanks for the upload. Always had a fascination with cold chisels, especially the way traditional gunsmiths use them. Today the cold chisel is still often used to cut out material in ribs for claw mounts. In the old days, the cold chisel was one of the first tools you got to use when starting an apprenticeship. And was the predecessor to the milling machine. It is possible to build a whole gun with hand tools like this. Except of course the barrel that needs boring et c.
i've been following your videos for a couple of years now , you are a great source of information and inspire me to get back in to the forge .I love your" DF-in the shop " channel. thank you for your excellent guidance .
Thanks for sticking around. As you know I was having a lot of problems getting videos out back then. It's a nice surprise to find out how many followed me over here.
Thanks to this video I realised I could change my mechanics chisels into single edge types with my dremel & the grinding attachments. Single edge seems best for working in tight spots
This is a very interesting video. It helped me visualized the cold chisel which we aren't able to try using since there are no lab classes. Thank you very much for this!
Super helpful. I have become pretty proficient in all sorts of things over the years, machinework mostly, but chisels eluded me. How amazingly useful !
Excellent! I've done very little cold chisel work on steel, but have used wood chisels on aluminum some with good results (even tried a beat up wood plane on aluminum too).
I found this gastropod fossil I am going to go get out of limestone, all I have is Dasco 3/4 cold chisel and a railroad spike, hope things go long journey, I learned from your vid thanks.
You probably had searched The wiki but just to be safe I'm going help you identify a cold from a hot chisel a cold chisel has a duller steeper bevel edge(the angle of the chisel that forms a v shape) it's for preventing the edge from breaking a hot on the other hand has a less incline bevel but must only be used when the material is at forging temperature but if you insist though it will break and nothing will happen
I wish I knew you back when I was making knives. I used to drill a row of holes in the brass or nickel silver guard that the tang went through and then it took me forever to file it out square with needle filed. I could have just made a punch like you did here to get most of it!
I recently pulled out an old 2" steel pipe fence post that someone had set in place with about 200 pounds of cement! I used a rotary hammer to drill holes in the concrete to weakn it, and broke a ten pound sledge hammer trying to break up the concrete! So I pulled out a 5/8" Proto cold chisel and a two pound hammer as a means of breaking up the concrete. That was still a lot of work, but with more hole drilling I broke that up into smaller pieces I can dispose of. Other than some minor mushrooming of the head, there was no damage to the chisel, much to my surprise. That must be some very hard steel! Having succeeded with that, I looked up Proto cold chisels, and that looks like a quality product. From there, I went to You Tube to look for idea on how I should use a cold chisel, and your video has been an education! Thanks for the ideas! Any comments on using a cold chisel on concrete like I did? It worked pretty effectively and did not apparent damage to the chisel, so peraps this is an acceptable use for the tool.
People say that blacksmithing is a "lost art" or whatever but i think that cold working metal is waaaay more lost to most. i really need to make some more chisels.
Do you have another video that would include information on a hot-cut chisel? Specifically the recommended angle and temper characteristics....I thought it may be a greater angle to push away material.
thank you for these! I'm curious. when cold chiseling, especially with a double bezel, am I correct is the observation that the chisel will follow the angle of the bevel? so if I hold my chisel on too steep an angle it will go too deep instead of just shaving off the excess? hope I worded that right
Yes there is always one side of the chisel ( bevel ) that is controlling the cut. The bevel that is rubbing on the work is acting like the sole of a woodworking plane and prevents to cutting edge from going to deep. So if you raise that bevel off the work than you loose that control and the chisel will tend to dig into the work. Also that is why the bevels need to be ground flat. If the bevels are rounded ( convex ) you will not be able to register the cutting edge to the work.
Hi DF, Thanks for your video, how would you go about cutting a thin and shallow gouge (~1mm deep/wide) in stainless steel? I'd like to cut into a blade for inlaying copper wire. Thanks again :)
Work that fine isn't done with a gouge but with a graver that has a solid cross section so you would grind the stock to the thickness you need and profile the cutting edge to the shape you need. Paul Hamler has a couple of videos on wire inlay that will probably help. ua-cam.com/video/AN9Yzbgepj8/v-deo.html
denis do you have a video on making your chisels, I am interested in making the padlock that's in your videos but not sure on the chisels, thanks in advance
This video was posted more than 4 years ago, but I only watched it now. I dangerously assume that this chiseling demo was done on 1018 or some similar mild steel. Any idea how this will work on normal medium or high carbon steel and really pushing the boundary on more brittle brass, bronze or copper?
All my chisels are just made by recycling spring steel. The links for my heat treating & forging carbon steel videos are in the description for this video
Any cutting edge tool will only work in materials that are softer than they are. The 1095 would need to be tempered to at least a spring temper. Even then the cutting edge will dull very quickly.
Chisels have always just been a blunt bludgeoning tool for me, very interesting to see the finesse they can be used with! Some of your chisels look like they might have started life as coil spring material, is that correct?
I make all my tools out of recycled scrap steel, usually coil springs or leaf springs. The most common steel used for coil springs is 5160. Plain carbon steels are identified by a number 10 as the first two digits in a 4 digit code. The last two is the amount of carbon in the steel. 5160 would be the same carbon content as 1060 but the 51 defines it as a different alloy. 1075 or 1090 is usually used for fine cutting edge tools.
Is it a requirement that you just always have dirty hands to be a blacksmith? 😅 Seriously, though - thanks for all these videos. I’m spending hours watching them all, and will probably continue to do so for many years to come. This is an amazing resource.
This is mild steel and I don't usually have any problems with it. If you run into trouble first check the chisel and make sure its right especially if it is a new chisel. If the chisel is sharpened correctly and works fine on other pieces than you will need to try annealing to see if that corrects the problem.
'm no Xpert on cold chisels. However, I just used a Proto brand chisel in breaking up about 200 pounds of concrete so I could dispose of it. Drilled holes in the concrete with a rotary hammer then used the cold chisel sort of like a wedge, which could be pounded in to break the concrete. When I was done, I was amazed ----not a trace of damage to the chisel! From that I conclude that Proto must make good cold chisels. They have some excellent on line catalogs, too.
No problem - I also have three videos on forging and heat treating carbon steel. They explain the whole process. This is the first in the series ua-cam.com/video/ZYO06j9Lgg8/v-deo.html If you have any other questions fell free to email me anytime.
The process for making wood chisels is the same as for making cold chisels. Wood chisels need to be tempered around a dark straw to red brown colour and the angle of the grind is around 25 - 30 degrees.
@@df-intheshop330 Dang. Oh, when are you going to work on another betty lamp? Like, one with a hinge lid? I think seeing you do that would be amazing. I myself am working on a betty lamp that is similar and I took some tips from your last video about a lamp. That one just seemed a bit.... empty
These question(s) is for anyone knowledgeable - obviously including the creator, who did an amazing job. 1) As far as measuring the angle, the 2 examples given were 55 and 60 degrees, can anyone explain what this actually means. My brain didn't pick up on the "included angles" what with the hands. This isn’t a knock on the creator - my brain just sometimes doesn't pick up what others are throwing down, even if its a really simple concept. Abd 2) when he used the chisel to go through the material between the drill holes..... why would someone need to do that? It looked super cool and i immediately started looking around for something to smash through - but i still don't know exactly why that ninja move would ever come up in real life. Then again, Im brand new to the chisel scene - so im looking to absorb as much knowledge as possible. Kinda one of those guys who has a mental block on things unless/until i see where the application for said use may lie. Really cool stuff and i learned WAY MORE in just a few minutes than I'd learned in the past 47 years of 'informal study' on the topic. Once again - really cool video and it's cool that so many people are interested in this type of material. Thanks!!
1) The ground surface of a cutting tool is usually called the bevel. A cold chisel cutting edge is made up of two bevels that are identical. If a cutting tool has two bevels that are not equal, the largest bevel is referred to as the primary bevel and the smaller bevel is called the secondary bevel. In either case, both bevels added together would be the included angle. 2) The slotting punch was used to quickly remove the web between to or more drill holes to provide access for other tools like engraving chisels or files that would bring the hole to it's final dimensions.
@df-intheshop330 Well I really appreciate the direct answer and your descriptive of what you explained in the answer. I think are giving me a bit more credit than is due because even though your description is GREAT, I think it's still over my head because I'm just trying to figure out on what part of the ground cutting edge is 55/60 degrees lol!!! And your answer, to the second, is excellent. I have a feeling that "where is this used and what is going on here" will sort of work itself out as I get a better grasp of this trade in general - but super informative stuff and really cool, yet relatable and simple, presentation system. I'm definitely a fan and I'm quite excited to learn more in your classes coming up here Thanks ,once again €for posting this content and I'm looking forward to seeing what you have in the pipeline
No problem. I'll take another shot at it because this will really slow you down until you understand this. Sharpening tools is a very important skill. If you look at a woodworking chisel. It has one ground face that goes from the top of the tool to the other side where it comes to a point. In this case the bevel angle is measured from the flat face of the chisel. The cutting edge of the chisel is the base of the angle. On a chisel that has two bevels the base of each bevel turns into an imaginary line that runs parallel to the body of the tool. So for a cold chisel it has two 30 degree bevels. Each bevel is measured from an imaginary centreline in the tool because the bevels are equal. As for the slotting chisels that was used mainly in the early days of the Industrial Revolution. They din't have all the milling cutters that are available today so there was still a lot of hand work being done before a part could be put on a shaper of planning mill.
@df-intheshop330 OOOOOOOHHH - OK yeah that makes a MASSIVE DIFFERENCE in my overall understanding of this. You are the first person to actually make sense, not "kinda makes sense" or "yeah I think I get it" this makes PERFECT SENSE!! You dumbed it down for me in the most basic way, but I actually get it now. I love machining and engineering videos, and I'm just now getting in to metalworking, and as such heat treating, and although I've watched a lot of the "big names" out there, they have one common flaw (not a fair word because I'm not in their shoes) and that's that simple concepts for them are glossed over as nothing because said concepts are so far in their past that it's easy for them to not realize that we're not all on the same learning baseline. And some of those channels are so large that if they were to respond to every basic/elementary level question, they would be giving their wives or husband's or grandchildren absolutely no time. So with that being said, not only did you answer my question(s) in the nicest and most polite way possible, you also answered them in a way that couldn't be more clear. I actually get it!! And I appreciate it - seriously! Now please go enjoy your weekend - I'm sure there are other people who appreciate your knowledge and willingness to help others as much as I do. I'm looking forward to the rest of your videos!
150 years ago masonry chisels were still often cast iron, or rought and cast iron mix (until cast steel became common) and were only used with a wooden mallet....they had a mallet (nail like) head striking end but for granite they needed tougher cast STEEL and fatter chisels....like cold chisels but one inch thick....japanese are the best at traditional chisel making for tough material....(europe is mostly limestone so wood chisels workedfine)....they fire sharpened them on the job at days end.
Thank you for sharing this. There is something satifying about removing lots of metal with a cold chisel.

Como fazer esse tipo de ferramentas?
This video was posted more than 4 years ago, but I only watched it now. I dangerously assume that this chiseling demo was done on 1018 or some similar mild steel. Any idea how this will work on normal medium or high carbon steel and really pushing the boundary on more brittle brass, bronze or copper?
The same chisels work on high carbon steel that is properly annealed.
can i know what types of steel you're using? thanks
sorry how do you heat and temper. what steel do you use.
All my chisels are just made by recycling spring steel. The links for my heat treating & forging carbon steel videos are in the description for this video
Is it feasible to score/fracture hardened 1095 spring steel, or stainless alloys at .035" with these?
Any cutting edge tool will only work in materials that are softer than they are. The 1095 would need to be tempered to at least a spring temper. Even then the cutting edge will dull very quickly.
Chisels have always just been a blunt bludgeoning tool for me, very interesting to see the finesse they can be used with!
Some of your chisels look like they might have started life as coil spring material, is that correct?
Thats right I always use coil springs or old crow bars
cheers, think I might start out with trying to make some small chisels when I get my forge going.
Is that "tool steel" that the cold chisel is made off? Are there different grades of tool steel, to ask for at the metal store?
I make all my tools out of recycled scrap steel, usually coil springs or leaf springs. The most common steel used for coil springs is 5160. Plain carbon steels are identified by a number 10 as the first two digits in a 4 digit code. The last two is the amount of carbon in the steel. 5160 would be the same carbon content as 1060 but the 51 defines it as a different alloy. 1075 or 1090 is usually used for fine cutting edge tools.

Could you show or use those chisel on hot metal also
No these are to be used on cold metal only.
where did you get that awesome grinder?? May I please have the makers name and site of sale?
That was a yard sale find. There is only part of a tag left. It looks like it says Wisconsin? I'm not aware of anybody making these anymore.
Can it cut mild steel or annealed steel
Yes, everything I'm working on in the video is mild steel
Do you anneal the piece you are working on first?
Or does that depend on the metal/project?
This is mild steel and I don't usually have any problems with it. If you run into trouble first check the chisel and make sure its right especially if it is a new chisel. If the chisel is sharpened correctly and works fine on other pieces than you will need to try annealing to see if that corrects the problem.

what's your go to tool steel? for chisels thanks love the videos
I use coil springs or crowbars simply because they are the most readily available. 5160 seams to be the most commonly steel used for springs.
thanks just getting started in blacksmithing
No problem - I also have three videos on forging and heat treating carbon steel. They explain the whole process. This is the first in the series ua-cam.com/video/ZYO06j9Lgg8/v-deo.html If you have any other questions fell free to email me anytime.
What is cross cut chisel & half round chisel???
"cross cut" and "round" describe types of files, not types of chisels
Where can I buy a set of these?
You might look up Proto tools ---- they have some good on line catalogs.
Would using a cold chisel on wood work well?
The process for making wood chisels is the same as for making cold chisels. Wood chisels need to be tempered around a dark straw to red brown colour and the angle of the grind is around 25 - 30 degrees.

I love machining and engineering videos, and I'm just now getting in to metalworking, and as such heat treating, and although I've watched a lot of the "big names" out there, they have one common flaw (not a fair word because I'm not in their shoes) and that's that simple concepts for them are glossed over as nothing because said concepts are so far in their past that it's easy for them to not realize that we're not all on the same learning baseline. And some of those channels are so large that if they were to respond to every basic/elementary level question, they would be giving their wives or husband's or grandchildren absolutely no time. So with that being said, not only did you answer my question(s) in the nicest and most polite way possible, you also answered them in a way that couldn't be more clear. I actually get it!! And I appreciate it - seriously! Now please go enjoy your weekend - I'm sure there are other people who appreciate your knowledge and willingness to help others as much as I do. I'm looking forward to the rest of your videos!
What kind of steel is best for cold chisels?
The chisels I'm using here are just made from coil springs. See heat treating videos. I've never worked with anything else.
have you ever tried making a file or rasp?
No but it is definitely on the list.
Sweet.
DF, check out Clickspring's channel. he's a remarkable maker. he makes files from mild steel the way the ancient greeks would have made them.
It looks like you made most of your chisels yourself. What kind of material does one use to make a cold chisel?
I recycle everything from scrap - usually old coil springs. See my heat treating videos for more info.
one strike one look
150 years ago masonry chisels were still often cast iron, or rought and cast iron mix (until cast steel became common) and were only used with a wooden mallet....they had a mallet (nail like) head striking end but for granite they needed tougher cast STEEL and fatter chisels....like cold chisels but one inch thick....japanese are the best at traditional chisel making for tough material....(europe is mostly limestone so wood chisels workedfine)....they fire sharpened them on the job at days end.
who sells a handcrank grinder?
I don't think anybody still makes these but they can be found at yard sales and antique shops that deal with tools.
hey df i want to send forge (if you can call my rubbish a forge at all but have lost the email could you send it to me
found it
great
