Cheap TTS style collet chucks

[SCzEngrgGroup]

Hi,

Can someone please tell me what thread is used in the shank of the TTS and how deep it is?

If not threaded, diameter and depth of the hole?

thanks

There are no threads in the shank of any TTS holder, and the bore size is different for different holders. Some have thru-bores as large as 1/2", some have no thru-bore at all.

Regards,
Ray L.

I have real Tormach ER and Weldon shank style TTS holders plus some ER ones from Darkon and none have threading inside the shanks. The diameter of the shank OD is 0.750. See http://www.cnczone.com/forums/attach...1&d=1168031791 for a drawing of the screw type holders.

Thanks for the pointer to the drawing, kstrauss.

Also thanks SCzEngrgGroup for clarifying the mystery of the shankhole (sounds like something nasty you'd call someone, doesn't it?)

Anyone know the diameter of the toolchanger disk, as well as the ID's and depth of the collet clearance well?

I Just received some collet chucks from YSTools. Very happy. All surfaces nicely ground.
Clocked em up on the shank of a endmill and they are more accurate then my Tormach tts holders.

Just wondering if anyone has tried YSTools 50mm Face End Mill Cutter?

It's most likely these guys. I think I'm going to pull the trigger on a set of these today. I need to see if they sell ER16 sets as well.

It has a longer shank so I'm not sure if this would be a problem. At work so can't check.

On a second look I don't think it would work. The surface that sits against the spindle is not ground and looks too small

[kstrauss]

I doubt that it is too small since it appears to be about the same diameter as the body of the 50mm face mill and these are typically 1.75 or larger at the base. You could always add one of the TTS adapter rings from Tormach and cut off the too-long shank.

[Labern]

Good point.
I did think of the adapter ring. Problem is I live in NZ this all adds up to expensive shipping costs for an Unknown/tested tool.
The ring would also take up some of the longer shank so it may not require cutting.

YSTool 50mm Face End Mill including 10 carbide inserts $65 + Tormach Adapter ring $17.50 = $82.50 USD plus shipping cost from both companies.
Tormach TTS 2" Shear-Hog (50mm) including 2 Carbide Inserts $395 plus shipping
Or you could compare it against the Tormach 38mm Face Mill with TTS arbor and 10 Carbide inserts for $316.41

I bought one of these about a year ago from YS Tool and it has worked well:
