I bought some Valenite indexable holders, specifically these:
http://cgi.ebay.com/ws/eBayISAPI.dll...m=220333568636
which look like they hold the diamond shaped carbides - I figured I could
put them in an Aloris type BXA-1 holder - but I am wondering how they really
are intended to be used - I've spent way too much time looking around the
Valenite on-line catalogs without finding these things - with any luck
someone on the NG will know exactly how they are used and what I should use
to find them in the Valenite catalogs. Of course if that doesn't work I can
contact Valenite, but I hate to bug "real" companies with a triviality like
this when we can all sit around and chat about it here.

if you don't want to look at the ebay link, the little things are marked:

MSKNR-10CA-3 the R of course means right handed, I was able to decode some
of the rest of the part number, but it isnt' at all obvious why they have
the little special set screw in the back nor the oval hole in the middle.
Do these go on boring bars? a special "mother" holder? or what?/?/?

Page B44 in the Valenite June 2007 Turning Tools print catalog.

It's a 75 degree lead facing tool. That is, about all this is good for is
facing ends of stock in a lathe.

Takes square inserts in the SNxx style, seems like the 322 size.

Maybe the set screw in the back was added to plug a coolant passage option?
This feature doesn't appear in the catalog, but neither does the "CA" in
the designation.

sooo, how is this thing held in the lathe it was designed for? it looks to
me like it's a cartrige type thing, the units I have are sealed in valanite
pakages, so there is no "user modifications" per se - does it bolt to a CNC
thing of some kind? Facing stuff off seems like a useful capability, so I
guess I can use them

But, they don't seem to be in the catalog I can download - if I decode the
part number using the info on page numbered 69 in the version I can download
now,

MSKNR becomes:

M = multi-option (for holding insert) - both clamp and pin
S = square insert
L = holder style, 15 deg lead end cutting angle, no offset
N = Negative clearance
R = right hand

-10CA is harder to decode from that page
10 = Square shank 1/8 inch shank height (this doesn't match the part)
C ???
A 4 inch length (doesn't match, actual length is 1.75 inches)

since that doesn't make sense, I assume that CA means "Cartrige"but I can't
find any representation of cartriges - is there any hint in the printed
catalog?

by the way, the on line catalog page numbers don't start with an alpha
character, they are just plain numbers. Very confusing.

Bill,
Go to www.valenite.com and click on "ValTURN Family", in the right hand
window is the link for the 2007 catalog. The section for your cartridges
starts on page 503 of the pdf, mounting info starts on page 598.

Yes, the 10CA designation is on page F20 for cartridges, not the regular
toolholder I gave before. You'll have to come up with a cartridge holder
for your toolholder, which doesn't seem worth it.

Hi Bill,

These are cartridge type insert holders used in purpose built tooling
using standard inserts. A long oval slot with an adjustment screw on the
bottom (and sometimes setscrews X-Y through the body) allow for large
adjustments in a seat. Most often used with large (toolroom made) face
mills, fly cutters, large single and opposed cut boring heads and
sometimes slot millers.

The cartridge seats in a nest (slot) and is adjusted for dia with the
small fine thread screw on the bottom. The oval slot is used to lock the
cartridge down.

For lathe use (I've never seen it done) the cartridge is smaller and is
intended to be locked into a hardened seat, the oval slot is shorter and
the cartridge may, or may not, have a bottom adjustment.

When you make you own tool holders then special "lead angles" are built
into the tooling. Also with very large tools, if there is a "crash" you
don't lose your hog, dog and frog...
