IC6025 (M20-M35)

ISCAR's IC6025 grade covers the ISO application range (M20-35) and is used for roughing and interrupted cuts, as well as applications at medium to low cutting speeds. The IC6025 grade is composed of a cobalt-enriched outer layer substrate, with MT TiCN and alpha Al2O3 coating. The unique SUMOTEC CVD post coating treatment was developed for machining stainless steel. IC6025 provides substantially improved tool life, excellent edge performance and repeatability when compared to our current grades and competitor grades.

SUMOTEC CVD Coating 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

  • Improved flank wear resistance

  • Improved adhesion to substrate

  • High toughness


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.

The SUMOTEC MTCVD coating adds toughness, flaking and chipping resistance and thus provides very reliable performance.

  • 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.
