Insert geometries
E-L50
Periphery-ground geometry
- Optimized geometry for shoulder milling and pocketing applications in titanium
- Light cutting
- Closer tolerance ensures better component quality and higher insert tool life
- Regulates chip formation and evacuation in sticky/long-chipping materials
- Predictable and gradual wear characteristics
M-M20
Direct-pressed geometry
- Optimized geometry for austenitic stainless steel materials and all application areas, especially for shoulder milling
- Light cutting geometry for duplex stainless steel and Inconel
- Good edge-line security and trouble-free machining at long overhangs
- Predictable and gradual wear characteristics
M-M30
Direct-pressed geometry
- First choice for medium and heavy applications in duplex stainless steel and Inconel
- Strong radius for higher security around the corner
- Highest metal removal rate in stable applications
- Controlled wear at the radius ensuring better performance in pocketing and contouring (ae ≤ 25%) applications in all ISO S and ISO M materials
