Hi DoN, I was thinking it may have been you that told me about the Aloris
type 16N holder, and I think you have a BXA or larger than the AXA/100
series toolpost.
Correct on both points.
IIRC, the genuine Aloris holder cost was near $200 at the time, $170 now at
MSC.
Hmm ... I paid $116.63 for my Aloris BXA 16N. This was from
MSC, but back in early 2003
The orientation of the inserts on the generic imports is different than the
genuine Aloris.
The tools4cheap seller is offering the larger holders, and their website
prices are lower than their eBay store prices, although shipping costs may
vary.

Oh! That one is very different from mine. Mine has the cutting
edge parallel to the mounting face of the toolpost instead of at 60
degrees as this one has -- and larger inserts too. I don't see any clue
that this has the carbide anvils under the inserts, either. I would not
touch it, personally.
I haven't purchased either of the holders that I mentioned earlier.. I've
been looking at tools4cheap and some other sellers for 3C collets, a
MT3-to-C3 adapter, and some other items.
I haven't used carbide cutting tools on my wimpy machines, so these
toolholders might not be useful to me until I get a better lathe, whenever
that might happen.
HHip states that the included inserts (AXA type 16E) are TCMT-3(2.5)1-HF.
Tools4cheap states his AXA inserts are tcmt16t308 (according to his
supplier).
Hmm ... the proper one for the BXA-16N is the TNMG-322 (I'm
using MSC's part number 07080062, though I have older ones which are not
TiN coated, and also not as sharp.) The AXA-16N uses a smaller size,
and presumably the CXA-16N uses larger. This is another bad point for
this particular dealer of yours (tool4cheap) -- where the same insert
size fits all three.
What you said about the insert height being precise on both ends is a wise
caution, since a lot of the cloned parts are often roughly-finished raw
materials which require finishing or else they're just miserable to use
(like the extremely poor quality HF/India AXA kit was, before I replaced it
by buying Phase II wedge and a piston models).
I think a good reason to avoid both of your cheap eBay vendors.
Hmm ... looking at the photo on the page devoted to the BXA
size, I do see what looks like an anvil under the insert. Hmm ... going
back to the AXA size, I guess that there may be one. But I still don't
like the angle of the insert. It makes you have to rotate the toolpost
to turn up to a shoulder and then face the shoulder. The CA clearly has
the anvil, but the whole insert and support are too small for the lathe.
CXA also has it.
Enjoy,
DoN.
