MC7100 / MP7100 Series

Dedicated Carbide Substrate + New Coating Technology
Creation of a new series for a variety of stainless steel applications.

Features of The MC7100 Series Coating

"Super" Nano Texture Technology

The standard Nano Texture Technology has been improved and developed to be an industry leading standard for crystal growth of Al₂O₃ coatings. This Super Nano Texture Technology increases tool life and wear resistance due to the fine, dense crystal growth process.

Tough and Sub Grip Layers

The extra strength of the adhesion between the coating layers suppresses peeling during machining of stainless steels.

New Coating Technology

The All Round Choice for Stainless Steel Turning
MC7125

Incredibly stable with both plastic deformation and chipping resistance

• Coating layer with high adhesive strength
  Tough and Super TOUGH-Grip dramatically improve adhesion strength and maximise the effectiveness of the coating.
• Substrate resistant to plastic deformation and chipping
  By optimising the particle size distribution of the main component WC and improving its dispersibility, reduced contact between the WC particles, dramatically improves resistance to plastic deformation and fracture.

• Machining SUS316L :
  Comparison of wear resistance during wet cutting

For High Speed Turning
MC7115

Increases the hardness of the base material, providing excellent resistance to plastic deformation and crater wear

• Coating layer with high adhesive strength
  Tough and Super Tough Grip improve adhesion strength and maximise the effectiveness of the coating. "Super" Nano Texture Technology suppresses crater wear during high speed cutting.
• Carbide Substrate That is Strong for High Speed Cutting
  The hard carbide substrate is resistant to the high temperatures generated during high speed cutting and has excellent resistance to plastic deformation and crater wear.

• Machining SUS304 :
  Comparison of wear resistance during wet cutting

Tougher for Interrupted Cutting
MP7135

The highly heat resistant coating and dedicated carbide substrate provide both wear resistance and chipping resistance.

• AlTiN-based nano-layer coating
  By layering the highly heat resistant AlTiN coating at the Nano level, excellent wear and chipping resistance has been achieve.
• Technology to improve adhesion strength
  Suppresses peeling when machining stainless steel and exhibits excellent chipping resistance.
• Dedicated carbide base material
  A carbide substrate exclusively for stainless steel that combines both wear and fracture resistance.

• Machining SUS304 :
  Intermittent Cutting Comparison

New Design Chipbreaker

MM chipbreaker for medium cutting

Excellent welding resistance
The sharp design of the corner radius and main cutting edge improves welding resistance and prevents problems.
