Toolmex or TOS? Peter Neill 10-06-2006

I need a new small 3-jaw chuck for the Myford. The inside jaws on my
Pratt 4" are fairly well worn and have been reground once, and I don't
fancy taking out a mortgage for a new set.

I've found both a TOS & a Toolmex in the 4"/100mm to suit, both very
reasonably priced - is there anything to choose between these? Anyone
have a preference?

Peter

Toolmex (based on bigger sizes)

Peter hi, I can't really help with your either/or predicament as I have
had both and found them excellent. I bought and used a 4" Toolmex on my
Speed 10 for about 10 years and I thought it was first class. The only
mistake I made was I let it go with the lathe when I sold it and
retained a Pratt Bernerd that came with the new lathe, the Toolmex was
better. I found it repeatable and accurate for a three jaw (none of
this 2/10 of a gnats *ss stuff but very good). It might have been
different model chucks of course but it appeared a little lighter build
than my 4" TOS but didn't seem to suffer from that at all. I still have
a 6" Bison which someone told me was an american market Toolmex and
again that is a first class three jaw.

I had a 4" TOS on my 918 lathe for the same sort of period and it too
was extremely good. Possibly not quite so accurate as the Toolmex but
it was older and had more use. I found it repeatable and as accurate as
any of my more expensive Pratt Bernerd chucks. Again I made the mistake
of letting it go with the lathe when I should have kept it. I also have
a TOS on my rapid indexer and it is an excellent chuck.

I would happily recommend either and will buy either again for myself
when necessary. From a purely personal viewpoint if faced with both at
a similar price I would go for the Toolmex as the one I had was
superbly finished and was as good after 10 years when I sold it as it
was when I bought it.

Best regards

Keith

Peter, bad form replying to my own I know but I forgot to ask where you
have found 4" Toolmex at that sort of price? I can find plenty of
places that sell TOS but seem to have missed those offering Toolmex.
I'm still looking for a birthday present and may well be tempted.

Regards

Keith

Thanks for all the replies. Not a lot between them but seems that the
Toolmex may have a slight edge so have plumped for this one and now
bought it.

Keith, the Toolmex was a lucky find from G & M tools of all places,
=A365 for new old stock with IS/OS jaws. Suprising as they sell new
stock 4" Toolmex for the Myford at =A3125.
Detail here: http://www.gandmtools.co.uk/cat_leaf.php?id=3D3178 but now
been sold <vbg>

Needs a backplate for the Myford but I can sort this out.

Peter
