Tool Holder Question: AXA16 vs. AXA16N
 

I had been putting off getting an AXA16N tool holder because of the
cost. So I was really disappointed when I missed the 30% off special
MSC had on Thursday and Friday. :-(

Nevertheless, it has given me more time to think about whether I need
it or not.

Since I have a Mini lathe which is not as rigid as the larger machines
I'd have to be careful what I use it on. My understanding is that I
can use inserts that have a chip breaker groove, but the push for me
to get one of these tool holder is that it'll allow me to get the most
out of each insert.(Six sides instead of three).

So until another deal comes around I'd appreciate opinions. Is my
logic faulty?

BTW. I'm looking at two eBay auctions and was wondering if these were
worth their price.

Thanks a lot.

Seems cheap enough.

I prefer to get tool holders with the square shank and put in an aloris
square shank holder. When (not if) you break a part, its cheaper to repair.

I alos like the cutting edge so its on the corner, not the 30 degree back
angle of these holders. Just a preference. It lets me change tools without
undoing the tool post and losing my DRO settings.

Regarding "six sides instead of three":
If you are planning to use "negative" inserts, I'd think again. I have
an Altas 10 inch lathe and it is not rigid enough for negative inserts.
I use the "positive" inserts a lot, but they only have 5° or 7° of
relief (I don't remember which).
You really have to PUSH the "negative" tool into the work before it
can cut. That's where rigidity becomes a REAL issue.
Sometimes I switch to hss tools when even the front relief on positive
carbide inserts causes too much twist for the job at hand.

Sorry missed that, he's thinking negative rake then. Won't work on his
machine. A positive rake insert with a small cut radius is the only thing
that might work on a light machine.

So is everyone saying that even for the softer stuff(ie: brass,
aluminum, plastic etc.) the 16N would not work at all for me?

The right inserts (with the right chipbreaker groove) give an
effective positive rake, even though the insert is held at a negative
rake.

BTW I do have an AXA12N that I will be experimenting with.

That is a start. It is half of a AXA-16N, so you can check how
it works for you for turning. What it won't do for you is facing. That
is what the other end of the 16N does.

Enjoy,
DoN.

one more point - I have both genuine Aloris and chinese clone holders for
the BX tool post - the genuine Aloris is vastly better - properly hardened,
better screws, etc - I don't see any reason to justify the cheap junk except
posibly for the BXA-1 and BXA-2 holders which are pretty simple - for
anything else, get the real thing in the proper size for your tool post.
