TTS toolholder

[RedpiperbobParticipant @redpiperbob16487]

Hi there can anyone help please I am looking for a TTS (3/4″ Straight shank) tool-holder that has a ER32 collet nut on the end. Like this only ER32 not ER16

I have tried emailing the two companies that I can find with no result .

 

Thanks

Bob

I don’t know if Tormach’s UK dealer does tooling or just machines but worth a try and they will be genuine parts not copies that you tend to find on ebay.  Or order from the US.

Thanks Jason Machines only

If push comes to shove, why not get an ER32 taper shank holder and make up a holder with an internal MT taper to suit the collet holder. The parallel shank holder can have provision for a drawbar to retain the taper shank.

Hi Bob, have a look at  CTC tools, catalogue item D20. (https://www.ctctools.biz/er32-3-4-x-4-straight-shank-collet-chuck-d20/)

ER32 collet chuck on 3/4 inch plain arbor 100mm long – and cheap enough.

I’ve bought tooling from them – er chucks and collets and been quite happy with them.

If Modifying other ER chucks you would have to add the collar to get the height registration that the TTS holders incorporate and if it is to go into a ATC equipped machine then you also need the groove to allow it to be held, this is a featrue missing from a lot of the copies too.

You could not run a longer shank if using ATC so the grip of an MT would be much reduced and they say you have to watch the load on a ER32 anyway as it can pull out of the spindle collet if loaded too much.

Thanks Keith I might try one.

Hi Jason I have modified a straight shank before for a 2″dia facecutter and it works fine in my homemade ATC but I am careful to take light cuts with it.
