Machining
Manufacturing molds and dies requires various
machining processes: turning, milling, drilling, reaming
and others, although cutting tools for die and mold
making are associated primarily with mills. The specific
character of the die and mold industry - predominance
of non-rotating parts, the complex shape of machined
surfaces, the necessity to produce a lot of cavities
that require considerable material stock removal, etc.
- positions milling cutters in the first place among tools
utilized by this branch.
In their constant need to boost productivity in
manufacturing molds and dies for new products,
the die and mold industry was one of the first adopters
of advanced machining methods such as high speed
milling (HSM) and high feed milling (HFM), and to
develop efficient machining strategies.

Tool Material Grades
In die and mold making, indexable extended flute
(also referenced as long-edge) milling cutters are
often applied to rough machining cavities and wide
edges. The cutters work in high-load conditions, and
the material of the indexable insert is a key factor for
improving tool life. To achieve this objective, ISCAR
recently introduced IC845, a cemented carbide
grade, that features a new tough substrate and a new
nanolayer PVD coating with applied SUMO TEC post-
coating treatment technology.
The grade was designed especially for cutting at
significant impact load. ISCAR’s solid carbide endmill
line has been enhanced by adding the IC702 carbide
grade, which is intended for efficient machining of
hard materials (up to HRC 65).
