what the heck collets does this holder take??
I have a new toy, an Abene mill, and it came with a collet holder
attached, but no collets. The holder is an INT 40 (or CAT 40) taper, but I can't figure out what collets it will hold - here are some measurements and data in case anyone can provide some guidance: Markings: LOFAB 3035 diameter of hole in screw on cover 1.511 inches diameter at front of taper 1.60 inches taper depth 2.90 inches whatever collet it uses will snap into the screw on cover, but there is no eccentric like one sees on some Erickson type holders any suggestions as to what else to measure to provide some idea?? It's not erickson, at least not any of the sizes I could find to try out thanks for any help bill Bill www.wbnoble.com to contact me, do not reply to this message, instead correct this address and use it will iam_ b_ No ble at msn daught com |

Sounds like it might be a C5 collet. Don't have my drawing handy, but
if it is, the taper is a Jarno taper. I am in the process of making an adaptor for my old Atlas, since someone gave me a full set of the collets. Bugs |

Thanks, but --- it;s most assuredly not a C5 - thie C5 is pulled by a
drawbar, wheras this collet holder has no threads at the base of the bore, and anyway, just for grins I tired a C5 collet and it's very much wrong - this is a single long taper, not a short taper like the C5.

I think that you are thinking of the 5C collets, commonly used in lathe spindles and in spin indexers. I suspect that the C5 is quite different, and may be what I have a few of in a 40 NTMB adaptor. I got mine at Cabin Fever a few years ago -- and the collets which I have are mostly uncomfortable sizes. :-) Enjoy, DoN. -- Email: | Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |

Here is a link to a page with some basic collet system drawings.
http://shopswarf.orcon.net.nz/colletmill.html Looks like it could be TG single angle collet holder. MikeH |

well, from that page, it seems that it might possibly be a Balas FlexiGrip series C80 collet - now the question is, where can I get one to confirm, or is there some other way to confirm?

If it's not needed in a rush, watch ebay. Buy one to confirm.
Otherwise call Hardinge workholding department. They may have some not listed in catalogs or may be able to make them. Is the collet holder removable? If the collets are hard to find or expensive maybe try a holder for a more common series collet. I googled "abene mill" and found this page: http://www.plastikosmd.com/AbeneMill.htm If this is the same mill maybe the owner of it would be interested in helping you.

Is the collet holder removable? If the collets are hard to find or expensive maybe try a holder for a more common series collet. Going back to the start of the thread, I verified my memory that this is a 40-taper adaptor, so yes, it is removable. There are a lot of such collet holders in 40 taper. I use some of them on my Nichols horizontal mill.

That doesn't usually work on the collet, though. I've got a TG100 holder in front of me and it's smaller, so if you've got a TG holder it's probably a TG150. John Martin |

According to John Martin :
Markings: LOFAB 3035 diameter of hole in screw on cover 1.511 inches diameter at front of taper 1.60 inches taper depth 2.90 inches whatever collet it uses will snap into the screw on cover, but there is no eccentric like one sees on some Erickson type holders [ ... ] Not sure what you mean by an eccentric, unless you're talking about the cam on one of the quick change systems. That doesn't usually work on the collet, though. Collet nosepieces like the ones for the Erickson ER series collets have an eccentric lip which hooks under a groove in the maximum diameter point of the collets. This eccentric lip allows the collet to be hooked under it and tilted into the nosepiece, and when you loosen the nosepiece, it draws the collet out enough so that you don't need to tap on the back of the workpiece to release it -- unlike the collets which came with my old Unimat SL-1000 all those years ago.

Enjoy, DoN. Thanks, Don. The TG collets have the same self-extracting feature, but they just snap in to the cap. It is handy. Wish my router had the same - I hate banging on the sides of the bits to get them to release. John Martin |
