So I broke one of the collets that came with my second hand mill, now trying to replace it.

Turns out what I thought was an ER32 collet is actually a Type B 50 collet, according to the dimensions as given in Machinery’s Handbook.

Anyone familiar with these and know where I can get replacements, preferably in Canada?

Thanks for reading.

Thanks for the reply Ken, I can't seem to find that product on their web site, how did you find it?

Thanks

MSC and Travers are two online sites that seem to have all the stuff we need and the good thing about them is they ship to Canada ,I know travers prices are in CDN dollars with a flat shipping fee, have not ordered anything from MSC but they are both well regarded here on HM.
I couldn't find that exact part you're looking for but either I didn't search hard enough or maybe the part # is different .

Thanks Ken, I’ve ordered involute cutters from Travers, quite happy with them. It may be that a phone call will facilitate my needs.

I will Bob, however I’m on the road until Tuesday, so that’ll have to wait.

The page out of MH is pg 971, 29th edition.

As you can see from the other photo, the length of the collet corresponds to a Type B 25 collet.

Does this help?

Is the diameter correct (35.05) for a type B as well?

As you can see the original split in 1/2.

Yup, that's broke!

Eric, those do look familiar.
If you are interested, I could check at my own local tool store this weekend and see what they have.
I will take your measurements and my calipers with me.
I can let you know prices and see if you're interested.

It was a 3/8" DIN 6388 type B25, right?

PS: I thought I had posted a picture once about teh baskets of collets they had in stock at the time...but i could bot find the picture.

That would be fantastic brino, yup it’s a Type B DIN 6388- Type 25 3/8”.

The thing is now, getting one off’s is one thing but if they’re not common do I look at a new system? (Smirk)

Nope. It's Cardon Tools just down the road from me (about 15 min door-to-door).
Here's their web site: https://cardontools.com/
(Full disclosure, I do have some family members that work there....in fact that website was built by my son.)

Oh, and I found one picture of a box of various collets.....

If you cannot read the tag it says $10 each.

Thanks brino,

That’s quite the collection and only one tub!!

I’ll definitely be looking them up and I like the idea of supporting local family businesses.

I just got a reply back from JL at Cardon tools, they currently don’t have any Type B collets in stock.

Thinking I’ll have to call a couple suppliers mentioned in previous posts.
