View Full Version : Square and Hex Collet blocks

12-18-2008, 08:37 AM
Someone posted some pictures of square and hex collet holders on here the other day. Where can they be purchased? I have looked for them ever since I saw them posted. Maybe I can't find them cause I don't know the proper name for them. Any help would be appreciated. Thanks

Thats why I love my paper catalogs, a lot easier to find something when you don't know what it is called.


12-18-2008, 09:20 AM
MSC, Enco, and many other tool suppliers have them.

Thanks, found them at enco.

You can get them off ebay too, right now item #220329045203 at $33. I have bought other things from the seller "Tools4Cheap". He had made a special run of 5V collets to fit Van Norman milling machines. Made in Tiwain about 1/3 the cost of Hardinge. So far eveyone who has bought them are happy with them, including me! He also sells the "spin indexer" which says made in China but seems to be the same as being sold else where. Has a lot of machine parts for older lathes and bridgeports. Wouldn't surprise me if he lurks here. Check it out.

It is not me!

hmmmmmmm that item number doesn't take me to that item or tools4cheap:confused:

Go to ebays main page. Do a "search for store" Plug in "tools4cheap" then search. I am not sure how to copy the address to insert in these posts here. Sorry.

FWIW: I have the square and hex collet blocks, but find that I use a SpinDex more. It's easier/faster for me to spin it to a new setting than to R&R the collet block, set it against a stop, etc.

Mind you, I've machined the sides of the SpinDex base so it fits squarely in my vise. It's beyond my comprehension why they aren't that way from the factory, but they aren't. At least the cheapys aren't.

OK I found it but its listed as item #400018113127

$34 at CDCO; search for 5C Collet Block Set

JTS has them on Ebay for $24.95, item 380091029863.

I find the collet block set a very handy tool to have. I use it in preference to the spin indexer whenever possible.

While the ubiqutous 4 and 6 sided ones are handy as all get out sometimes they just dont do the trick (and sometimes a indexer won't either). Thats why I made these


Plus I really don't like the performance of the Spindexers in the mill. But then I managed to score a Hardinge H4 Index Head off of the 'bay before things went crazy. :D

Nice set there SD. But I've not yet found a real problem with the 4 and 6. If it needs finer control, it's onto the Hartford most of the time. Like you, I'm not crazy about the "Spindex", though it's works marginally well enough (after pinning the wheel) on some stuff that would otherwise have been difficult. I also have the Hardinge HV lever indexer which is nice too, but most of the time when the Hartford won't do, neither will the Hardinge closer. They make optional index wheels for it with other than 24 positions, but they are not common.

Just another one of those things where it seems like you just need to have a selection of stuff in order to avoid getting boxed into a corner...

Nice adapters SPIN DOCTOR what material did you use and are they harden?
and how do they tighten down the collet, can you show a pic of the bottom thanks for any info.

FYI - you can also find "tools4cheap" here:


Click on "grinder tooling" on the left, you'll see the 5C blocks there. He is a few towns over from where I work. I have purchased some things from him, went to his place to pick them up to avoid shipping cost. It is a true one man operation, and the owner is a nice guy, seemed to be a straight shooter. He is an occasional advertiser in HSM, and I do seem to think I have seen him post here a few times. I could be wrong on that part, though.

I bought a uni-vise for my T&C grinder from him. New China made, quite nice really for 100 bucks. Which was considerably cheaper (half or more) than the many severely beat up ones I watched sell on ebay for a year or so. I did replace the typically crummy chinese hardware, but besides that it seems decent.

All standard disclaimers apply, I have no interest, nothing to gain, just a satisfied customer, this is not an endorsement, just my opinion, blah, blah, blah...

Same as any standard 4 or 6 sided collet blocks. Material is 4140 TG&P in its mill state. About 30 to 35 RC. This every thing needed to make the 5 sided shown less the v-block needed for grinding. With a little care they were all within .0005". Close enough for mill work. The primary reason is because I am interested in scale radial engines and odd sided collet block seemed a good solution to some of the fixturing problems

So the bottom of the holder is not recessed for the nut?,, Bill.

I have yet to see a collet block for 3C, which just happens to be my shop standard because it fits in the lathe and mill.........

All the blocks, AND the spindexers etc are for 5C. It's annoying.

Hmmm, and what was your advice for me J? ;)

About the collet closer spindle bushing. As you suggested to me, just make it. At least a collet block doesn't see the wear of constant opening and closing, so it would be an ideal candidate for making from pre-hard 4140.

Check HSM a few months back.................

Here is one, a bit beat-on from being used for a while. Needs the 'corners" cleaned up again.

Oh, well then, looks like a nice job... :o I don't believe I saw that post. I misunderstood what you posted earlier to be indicating that you didn't have one...

Of course you could also make a 5C to 3C adapter so that they would work in any common 5C device...

I don't believe I saw that post.

It was an article in HSM.......... I don't think I ever posted it here.

12-19-2008, 11:26 AM
Well, I'm on a roll! I misunderstood HSM to mean this forum rather than the magazine...
