one of the letters just describes the fixing...
now, lessee...
http://www.carbidedepot.com/formulas-insert-d.htm has a good list of codes.
I have CCMT09 on a smallish tool. In fact, the student would take a bigger
tool - this one is 12mm square. However, it's OK for what I do and you can
always put a block under it to get it the right height.
I also have a CCMT06 in a boring bar.
Rhombic 80 degree (which is the first C) gives you 2 points per insert and
lets you turn into a 90 degree internal corner from either direction without
altering the tool in the toolpost, which is something I do quite often,
turnign a bearing seating on a tubular part, it needs turning down to size
and a perpendicular surface for the bearing to seat against.

I use that Glanze tool in RH, LH (SCLCR/SCLCL) and in the design that
allows the use of the other two edges (SCLCR), I find them excellent.
I find the CCMT tip is widely used and also fits some of my boring
bars as well as a wide range of turning tools, They handle a wide
range of materials but for steel my personal preference is to use
uncoated CCMT 06 02 04 tips from Widea (still available from RDG I
think) as I feel they give a better finish. For stainless I use the
same tip in coated form (Sandvik) which I buy from Jenny at:

She does all the shows and her service is superb. I also have 10mm
holders from her and they are also excellent. I find these a very good
compromise for a wide range of work and materials and would not
hessitate to recommend them to you.
I also have some similar but much more expensive holders which are
first class. The potential problems with the holders are the accuracy
of the machined insert pocket and the quality of the holding screw, I
have found no problems with the Glanze versions although I do buy a
few spare screws with them.
Peter Neill is an advocate of the DCMT tips which I also use and they
do give slightly better access for fiddly jobs but for me the CCMT
does 90% of what I need. As they say you pays your money..............
Have a look at this discussion as although we were talking larger
holders the tip is exactly the same:
http://groups.google.co.uk/group/uk.rec.models.engineering/browse_thread/thread/5d6eb7531e0d9841/50d73d31a29f52e2?lnk=gst&q=bh600+tools#50d73d31a29f52e2
I also use the 12mm holders and the TPUN inserts that John
Stevensons' Gert sells and they work really well. I don't think that
John does them in 10mm though.
Apologies for the very rushed answer which I hope helps a little. I
promise to do better next time as after recent events I unfortunately
will have more time to spend reading the forum.
Best regards
Keith

Yes indeed. Have only glanced at it, but it does not look as
comprehensive as the wallchart that MEW gave away a few years ago - that
had a really comprehensive list of what all the codes for tips and
holders meant.
If you need to find it, Peter, and no-one can tell you which issue it
was in, say so here and I will plough through my pile of back issues to
find which one it was.
