IC6025 (M20-M35)
Following the introduction of grade IC6015, ISCAR offering grade IC6025, SUMO TEC CVD coated, which was developed for machining stainless steel.
Grade IC6025 covers the application range of ISO (M20-35), used for roughing and interrupted cuts, as well as applications at medium to low cutting speeds.
The grade IC6025 is composed of a cobalt enriched outer layer substrate, with MT TiCN and alpha Al
2O
3 coating with a special post coating treatment. IC6025 provides substantially improved tool life, excellent edge performance and repeatability when compared to our current grades and competitor grades.
CVD Coating
SUMO TEC Post Treatment
- Improved toughness
- Improved chipping resistance
- Smooth chip flow
Alpha Alumina (Al2O3)
- Improved crack resistance
- High resistance to crater wear
- Improved chipping resistance
Intermediate Layer
- Improved coating resistance to peeling
TiCN (MT)
- Improved flank wear resistance
TiN
- Improved adhesion to substrate
Substrate
Features
Substrate
Although the coating process of the IC6025 is similar to that of IC6015, it differs with a tougher substrate, featuring a combination of high toughness and deformation resistance.
Coating
The SUMO TEC MTCVD coating adds toughness, flaking and chipping resistance and thus provides very reliable performance.
Applications
- Turning stainless steel at moderate cutting speeds
- Stable or unstable conditions

The two new grades (IC6015 and IC6025) combined with the new chipformer configuration provide a completely new standard for machining stainless steel.
IC6015 covers the high speed machining area for continuous machining of stainless steel and high temperature alloys, while IC6025 is recommended for the interrupted cut applications.
IC907 / 807 is our first choice for machining S.S.
Developing the family of the 6000 series makes it possible to achieve much better results than IC907/ 807 in machining S.S.
