How to Use Collet Blocks

- Here's a how-to guide for collet blocks. This goes along with my indexing lecture for my intermediate machining class at Parkland College.

I saw another youtuber mention Collet Blocks and didnt know what theyre used for so here I am.. Now I need to find a video on what indexing a part is and what the index values 2, 3, 4 and 6 mean. Thanks for the video.
Thanks so much for taking the time to make these videos. Every one of them has at least one little trick that I have never thought of!
You are an encyclopedia of excellent information!
Thanks for sharing your knowledge and keep up the great work!
Thanks for the video on collet blocks. They are very useful time savers.
Excellent! I entertained myself for a week with a set of 5c blocks and tilting the head on my PM25 mill......unbelievable what you can come up with. I had never seen a 5c chuck before.
The chucks are handy when you need to hold something bigger in one of the 5C indexers like these or the spindexer. They're not that expensive either.
Glad I found this video, I wanted to make sure I could use these up and down in the vice without the lever deal on the bottom, should work perfect with just the locking ring!
very helpful....learned some great stuff.....cheers, Paul from Florida
Good stuff. I've learned a lot from you over the past few months... thanks.
5C collets are obviously the most versatile due to the multitude of chucks and attachments built for them. And 5C is probably used almost everywhere in the world today. But the same 4 and 6 sided collet blocks are also made for ER 32 and 40. Arc Euro Trade in the UK is one supplier for them. Much too slow to use in industry, but they are another option in a home shop that's already using ER collets.
Yes. I use ER32 extensively in my shop on the mill and the lathe. I have a 5C to ER32 adapter that I use quite a bit for oddball sizes since they hold over such a wide range. Since the video was meant for my class though, I decided not to muddy the waters on this one. I'm going to do a separate video on the wonders of ER collets sometime in the future.
@@StuartdeHaro I sometimes forget that some of your videos are meant for your classes and not as general YT videos. One of the main reasons I chose an ER 40 collet size for my R8 mill was the dual usage on it and lathe. If money were no object I would have gone with the 32 size for tool holding on the mill and 5C for work holding on the lathe and mill due to it's obvious superiority and speed of use. I think a good video about ER collets is more than worth while. I had to do a lot of digging on various web sites including Rego -Fix before I fully understood how to properly use them. Some of the details aren't quite as obvious as many with home shops seem to think. Tool movement due to inadequate nut torque being just one of them.
That's the reason I went with ER32. I already had collets I was using in my lathe and I had a mess of collets.
good job,very informative.
Concised and interesting
SO these mean I need ANOTHER set of collets? I was hoping to utilize my r8 collets, but now I see that was wishful thinking. I'm going to need another GARAGE! Thanks Stuart for the lessons. They help out more than you know!
There are collet blocks for other collets too, I bought blocks for ER32 collets since I already had those. Don't know if there are blocks for r8 though.
@@tomasclasson The downside to using r8 collets would be the lack of pass through. Oh well.
Thanks for the prints!
You're very welcome!
Sometimes it takes time for a video to surface .... hang in there. Thanks!
Never though to use a V block to get the extra split on the angles. !
I can't tell you the number of times I've seen someone do something in a machine shop and I just said, "That’s so simple. Why didn't I think of that?"
I use an ER40 six sided block as a way to run collets on my lathe.... The chuck doesn't hold stock smaller than 5/8" very well, using an ER series collet means the block can stay mounted in the lathe when changing parts... The 5C collets need to get pulled out of the chuck to swap parts... I'd love to have an actual collet chuck for my lathe but a setup for a D1-8 gets pricy... The collet block is a cheap & easy hack... If I really need precision I can use the four sided block in the four jaw....
I did that for years with a straight shank ER-32 holder in my 4-jaw chuck.
Was good except for holding on corners which is high- risk unless you use vee blocks, and either way changes the height of the part.
I was still watching
I was watching your splendid video again and came to some thoughts.
I am living in the Netherlands Europe. I owe many Swiss machines with W12 W15 ans W20 collets. E.g. a Schaublin 102 VM with the W20 collets. We use the metric system and my collets go up from .4 mm to 20 mm in steps of .1 mm. Alltogether about 200 collets.They came from an auction of a Swiss watchmakerfirm. ( I had to drive 1600 miles but the price was it worth) These kind of collets are simular to the 5C collets.
I think there is a major disadvantage of these collets to the ER or ESX collets. The last ones are far more forgiving for grabbing a workpiece considirably thinner without loosing their roundness.
The ER collets can be achieved in ultraprecise collets which are much more affordable then a set of C or W. Collets.
Why do you and your TH-cam collegues chose for the 5 C collets? Is that because of your spindle nose ? Or are there other reasons.

5C collets are VERY common in the US. They're available in round, hex, square, and rectangular. You can get them in. 001" increments. Of course there are metric sizes as well. There are machinable collets, expandable collets, fixture mounts like I mentioned. Tons of different tooling uses them, like these blocks and several other indexing devices and fixtures. They make a lot of them, so they're pretty affordable. You can use collet stops. The list is pretty long. ER collets are used a lot as well, but mostly for milling. They are starting to get a foothold in the lathe market, especially on the hobbiest side of things since the chucks are simple and affordable. The wide holding range for each collet is very attractive. Anyway, that's quite a wall of text to answer a simple question. Thanks for watching!
What happens to ducks that try to fly upside down?
They quack up...
Hey, you asked! 😜
Nice.
Question, the screw in the block and the slot in the collet is that for lining only or should it be tightened?
Thanks, Robert
It's for aligning the collet and holding it still while you tighten the ring or the cam.
@@StuartdeHaro Thanks for the reply.
How about R8 collets, are there commercial blocks available for those? How hard would they be to make?
I don't believe there are, but they're not complicated to make. You just need to ensure that the bore is centered on the blocks. That's the most important thing, followed very closely by the accuracy of the angles.
Nice video.
A man walks into his house with a duck under his arm.
He walks up to his wife with it and says, "This is the pig I've been f*cking'."
His wife says, "That's a duck."
He quickly replies, "I wasn't talking to you."...
Classic!
Hi Stuart, Thanks for the video on collet blocks, I use an ER32 12 sided collet block, very handy, they are listed here
www.mag-pro.com.au/goods.php?id=469
in Australia where I am, called a Joe collet block. It allows you to do square, triangular, hex etc all with the one block. They also come in ER40.
M R Ducks,...M R Not,...O S M R,...C M Wangs,...L I B...M R Ducks! Best I could do.
Your best is all I can ask for. Thanks!
There's nothing funny about ducks! Great video series, though.
