Indexable inserts for machining ISO-P steels

Machine steel efficiently

Higher performance or longer tool life? You can have both!

ISO-P steels can be demanding to machine. The versatile range of ISO-P indexable inserts provides high-performance solutions for turning and drilling of ISO-P steels.

longer tool life

compared to competitors

Tool change before tool breakage: indexable insert "predicts" loss of tool life

→ 10 cuts

→ 1 cut

Wear detection means that optimum utilization of the multi-edged indexable insert can be identified with a quick glance at the cutting edges. Wear on the cutting edges is also easier to see and easier for the machine operator to identify.

A comparison between the wear detection of our new ISO-P insert (CTCP115-P in the example) and its predecessor insert is shown here.

Predictable steel machining

Due to the vast range of ISO-P materials, machining can be challenging. To make machining the biggest material group in metal machining easier for machine operators, we have rethought everything from the substrate to the geometries, right through to the coating – for optimal breakage resistance and hardness of cutting edges. The Dragonskin coating's optimized layer structure is designed specifically to:

  • Increase tool life
  • Reduce machining times

Test report for the old and new ISO-P turning indexable insert

 > CTCP115-P turning grade in the example

 

Indexable insert: CNMG 120408EN-M50
Material: 1.2343 – X37CrMoV 5-1 44 HRC
Cutting data: vc 70-130 m/min | f 0.35 mm/rev | ap 2 mm

Performance increase of the new grades:

Cutting speed vc Increase in %
70 m/min 20
100 m/min 44
130 m/min 45



Result: Depending on the cutting speed, an increase in performance of up to 45% can be achieved with the CTCP115-P grade.
