THREAD TURNING PENTA is an all ground insert where each cutting edge on
PENTACUT Threading Insert with 5 Cutting Edges for External Threading

the pentagonal shaped insert is equipped with a unique
chipformer that provides excellent chip control, short and
easily exposed chips, high accuracy and surface quality.
The insert is tangentially mounted on a side of the holder,
positioned against two peripheral contact surfaces to
ensure accuracy of the center height. Clamping of the
insert is by a side torx screw. The torx screw can be
activated from either side of the holder to enable insert
indexing (rotation) without having to remove the holder from
the machine turret, i.e. easy and fast edge indexing from
either side of the holder. In case of edge breakage, the tool
will survive, and other cutting corners still can be used.
The PENTACUT line offers solutions for partial profiles
and full profiles for most popular standards and is
suitable for the production of external threading Iscar
producing also special solutions for internal applications.
The PENTA insert has a strong design and, combined
with a very rigid clamping system, enables threading
at very high machining parameters. This insert can
be used for threading between walls to enable
complete part production on bar feeder machines.
PENTACUT offers a very stable and economical solution.
