Thank you sir. The videos I've seen look like magic. It's spinning then it's not then it a shape appears in the metal and it's spinning again. The wobble and singular point of contact makes so much sense. Much appreciated.
I came here after watching someone do this for a project and was blown away when i seen him make a square hole with 2 spinning ends.. he didnt explain how he did it either.. which was a little frustrating... but alas, you explained it perfectly.. thank you sir!
First time I saw a rotary broach in action couldn't comprehend how 2 spinning ends were cutting a square hole. But 1° slope and slight wobble makes it clear that it's basically high speed chiselling
Yes we do. You can send us a print or find our standard ones here: www.polygonsolutions.com/rotary-broaches/special-form-rotary-broaches/involute-spline-rotary-broach/
The chips curl down to the bottom of the hole. You can easily remove them using ta drill or boring bar. Alternatively, you can put an undercut at the bottom of the bore hole, and the chips will just fall off. You can see an illustration here: www.polygonsolutions.com/rotary-broaching/
Hi, do you have information about external rotary brouching,?, I need to know the theory about this process. If you have a pdf book about this, please send it to my mail, I would be grateful. Thanks.
The “wobble and small cuts” was the key, I understand it just from that. Great video!
my right ear has enjoyed the video
RIP left ear
this is a mandatory comment.
Lmaoo I hear both?
this is funny because I only listened with my left earbud in, I thought the video was just really quiet
You explained this better in the first 70 seconds than all the videos I've seen today. Thanks!
My right ear learned a lot in this video.
Fully-explained in a brief and clear video. THANK YOU.

I found this video while trying to figure out how the broach works. Thanks for a good explanation!
Whas it this old tonys video
Very good explanation of how they work. Thank you.
Didn't explain it at all, in my opinion.
Great Explanation!! Though it would have even greater with some "Zoomed" of the tools as you speak :)
AND A FEW IMAGES OR 3D ANIMATIONS
my right ear really loved this video
Can you align the hole you’re broaching, or does the hole come randomly, with the corners pointing to which ever direction?
Yes you can align the broach using our alignment brake attachment: www.polygonsolutions.com/rotary-broach-tool-holders/rotary-broaching-brake/
Polygon Solutions Inc. That’s clever.

What is the difference between a 1 degree angle and a very slight 1 degree angle?
I know....
I am being funny here...
A very slight amount.
Thank you. This really helps me understand how broaching works.

Brilliant explanation thanks
Very well explained 👍
Do you offer involute spline rotary broaches?
Yes we do. You can send us a print or find our standard ones here: www.polygonsolutions.com/rotary-broaches/special-form-rotary-broaches/involute-spline-rotary-broach/
Excellent definition of broaching. Most people just say its magic and leave it at that. Lol
I get it now. Thank you.
excellent video!
Wow I never knew this crazy thing
OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO....
now I get it.
thankyou
Maybe pull the camera in a little closer so we can actually SEE what you are talking about.
So it has 6 features in total: 3 mentioned at the beginning and 3 at the end.
“A lathe”🤣 so humble🤣. Thanks though for the explanation.
But where does the metal go?
The chips curl down to the bottom of the hole. You can easily remove them using ta drill or boring bar. Alternatively, you can put an undercut at the bottom of the bore hole, and the chips will just fall off. You can see an illustration here: www.polygonsolutions.com/rotary-broaching/
Black Magic!!!
Nice
Good shit

Matias Rodriguez Buenos tardes. Pregunta te enviaron la información sobre cómo hacerlo???
Crazy
lol. still dont know....
