Five cutting edges make Iscar’s Penta 24 threading inserts a ‘star’ performer

Following the global success of the advanced Penta 24 inserts, Iscar has expanded Pentacut’s application range by adding threading options. The new Iscar inserts feature the ability to perform highly efficient threading applications. Full profile inserts are now available in ISO, UN, Whitworth and BSPT thread standards. In addition, partial profile inserts are available in 60o (MT) and 55o (WT) profiles.

The new Penta 24 inserts feature multi-corner, five cutting edges, which provide the user with an extremely economical price per cutting edge. The new advanced inserts benefit from the combination of a very rigid clamping system and a robust insert design, enabling production at very high machining parameters.


Penta 24 can be used for threading between walls to enable complete part production on
bar feeder machines, whilst the inserts’ innovative chipformer provides short chips, which result in excellent accuracy and enhanced surface quality.

The new Penta thread inserts can be mounted on standard Penta 24 tools and the system’s advanced design ensures easy and fast edge indexing from either side of the holder.

The new inserts are made from Iscar’s very versatile PVD coated grade IC908. Following an edge breakage, the tool will survive and all other cutting edges still can be used.
