Subject: Rake angle on ..MZ indexable inserts?

Got a question about indexable inserts (carbide, ceramic, etc).

When the fourth position (insert type) is Z, as in SNMZ or TNMZ,
what is the angle between the rake surface land and the (N=unrelieved)
edge of the insert?

Machinery's Handbook, 23rd edition, doesn't discuss Z as a possible
fourth position.

The 1986 Carbaloy catalog suggests a 10 degree land, but they use
a fourth position P, not a Z.
