The New 5 Cutting Edge Insert for
Economical Grooving, Parting and Recessing
ISCAR has developed a new insert with 5 cutting edges designated PENTACUT for multifunction applications including grooving, parting, recessing and chamfering.
This cost-effective insert is designed to perform shallow grooving operations and parting of small solid bars up to 12.5 mm (.492'') in diameter. Each cutting edge on the pentagonal shaped insert is equipped with a unique J-type positive chipformer that provides excellent chip control in grooving, parting and recessing (light side turning) applications.
The central recess on the rake face causes chip narrowing and curling, ensuring chip flow with minimal interaction with sidewalls of the machined groove. This chip deflector is efficient in a wide range of work piece materials and machining conditions. The insert also yields an excellent surface quality, especially on groove bottoms and sidewalls. The insert is tangentially mounted on a side of the holder, positioned against two peripheral contact surfaces to ensure accuracy of 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 the having to remove the holder from the machine turret. The short head of the holder ensures minimal overhang and high stability. The new PENTACUT tools can be mounted on any type of lathe.
