Dont you mean a-broached the subject

[@glipglop5455]

@John Doe Wiki - "Broaching is a machining process that uses a toothed tool, called a broach, to remove material. There are two main types of broaching: linear and rotary. In linear broaching, which is the more common process, the broach is run linearly against a surface of the workpiece to effect the cut." Merriam-Webster - Broach is "to open up (a subject) for discussion" They used the homophone "broach" as a pun. Wiki - "The pun, also called paronomasia, is a form of word play that exploits multiple meanings of a term, or of similar-sounding words, for an intended humorous or rhetorical effect." That's why it's funny.

[@Tyblorg]

I saw nothing wrong in this video. I can't believe the comments on here. AvE good job. People need to know feeds and speeds and the different cutting compounds available out there. The fact the drill was smoking proves you had a cutting compound on. The drill wasn't too fast for a 3/8 diameter. Belt driven drill presses always sound faster than they are really going. Also the drill bit never changed colour, the chips were silver and didn't turn purple which means you weren't cutting anywhere near too fast. I could brag about my credentials and certificates and pieces of paper too. It's what you can do, and what you really know, that proves your true abilities. Natural talent and innovation will always be worth more than a shitty piece of paper, this is why you can machine without a certificate for a living.

When I was 18, in 1978, I got a job at a small 30 person manufacturing plant, (there used to be a lot of those), one day a month I needed to broach a couple hundred parts, we used an arbor press with about a 2 ft. long handle on it. It was hard as hell to force that broach through, I started with the handle almost straight up, a little forward of TDC, I had to hang onto the handle, and let my legs drop out from under me, it took all my 180 lbs. to get that broach moving, that was the easy part, because that was only about halfway through, keeping the handle going to get the broach the rest of the way through was the hard part, it was a hell of a workout, and I'd be covered in oil. I'm sure there is a machine doing that now.

[@RickEverton]

Try rounding out the bottom of the broach to fit your starting hole diameter. Then cut your relief cuts. The broach will start round, as does the hole, then works itself into a square. No file work that way. You would have to make the broach longer with a longer tapper, but it works. Just sharing...nice work here, well done.

Pretty square holes can indeed be drilled. They used the method to drill the holes in the plates that railroad spikes go through. The 2 flute drill would go into a floating type ring which allowed the drill to walk around and drill the square hole.

[@dokterzorro]

I'd have to say his drilling is fine. It's fast, clean, no spaghetti and by the looks of it there is some kind of lube going on there. The smoke coming from the chips indicates al lot of the heat is transferred to them, not in to the drillbit. Also, the chips are not blue, indicating that it's not overheating anywhere. Drillbit looks fine too. Lastly, the reciprocating drilling technique he's using prevents te drillbit from overheating or re-grinding of the chips in the drill hole. All in all, a fine job, Sir.

[@tttrrroooyyy]

What's with all these ignorant Joe handymen that are so confident in telling a machinist how to drill a hole properly? You people wouldn't know how to calculate the ideal RPM even if you knew what the drill bit and material were. In this application a carbide drill bit shouldn't use coolant and should turn at 2-3K RPM. There's no chatter and it's making good chips but you never saw chips smoke in your high school shop so the professional must be wrong.

[@tttrrroooyyy]

john saunders Are you sure it wasn't two head injuries? I'm guessing you want to be a teacher so you can get paid to talk down to people. I've met a lot of smart tradesmen and none of them toot their own horn. The loudest guy in the room is the weakest. Or maybe it's the internet so you can be whoever you want and you choose a tin banging, boiler/ tool making, pipe welding, engine tuning, super engineering douche. Or maybe you're the outlier; a condescending genius prick that mixed up his numbers by accident. He doesn't say what material he's using but I'm guessing it's not brass. Assuming it's mild steel the cutting speed should be roughly 30 SMM. (318 x 30) / 9.5 = 1004 RPM. I used the imperial equation and got close that. (CS x 4) / dia. = RPM. I'm not sure why you used a metric equation on a 3/8" drill. As a rule of thumb carbide bit speeds should be 2-3X that of a HSS bit. That's how I got 2-3K RPM. Before you say it, I know it's rough and there are lots of variables that would make it faster or slower. It's a ballpark calculation just like your equation. If he can afford a milling machine he can afford some carbide bits. There are other reasons for not buying a broach. And stop spelling he'd as "hid". BTW, I'm a rocket scientist, lawyer, rock star that can bench 280 lbs. I won the elementary spelling bee last year so I'm pretty sure that qualifies me to be a spelling nazi on youtube.

[@HeplMeh]

***** You guys can laugh at john all you want but he is 100% correct. Any real machinist can easily tell a carbide bit from a standard hss bit by the color.

[@tttrrroooyyy]

***** So I think it's about time we ask you about what's going on instead of all this name calling over a guess. What is the drill bit made of and how fast were you running it?

[@andrewCNC905]

john saunders Wrong stupid 400 per inch for HSS and mild steel is more likley. And the proper equasion is (Cutting Speed x 12)/(pi x dia) And How do you fucks know its not carbide tipped drill. And second of all, maybe hes just drilling it quickly as to not lose people attention for the sake of a youtube video. not everything ia always black and white.

[@HesintheTaNaK]

john saunders You might have learned to use the metric system Johnny Boy but you are sore lacking in the spelling and grammar department. (ignoramace, simplten, sory, Rushians, metris,) But you are Australian. I'm sure your "Mates" are proud. I think the rest of you folks are jealous that this man has the ability you don't and he's willing to do it. you see it's not always about buying the tool. making it increases you skills!

[@sergarlantyrell7847]

Ah, this must have been from the years before AvE discovered the secret about where to keep his stick.

[@moderatefkr6666]

One of the things I like about square files is how they're tapered to allow you to get those straight edges in square holes. Assuming you're working with mild steel, judging by the thickness, if you marked it out on both sides and filed it, the job would have taken 20-30 minutes. Making the broach and then using it probably took a couple of hours at least. But now you have a broach, that doesn't seem to work very well...!;) But hey, I'm the guy who took three days to straighten a Ford Mondeo suspension arm (that some bastard mechanic had bent) using a combination of blocks, levers and vices, two straight edges, a homemade hardwood jig, blocks of wood, a jack and a fucking huge hammer!;))).
