JOMT06T215ZZSR-JM FH7020
Mitsubishi Materials | AJX06 Series Cast Iron Finishing & Roughing
The Mitsubishi JOMT06T215ZZSR-JM FH7020 is a specialized high-feed milling insert designed for the compact AJX06 series cutters. This insert is the definitive choice for machining Gray Cast Iron and Ductile Iron. By combining the wear-resistant FH7020 grade with the JM chipbreaker, it provides an exceptional balance of edge strength and friction resistance, allowing for high-velocity table feeds even in small-diameter milling applications.

FH7020 Cast Iron Specialist
The FH7020 grade is a specialized PVD coated carbide optimized for flank wear resistance. Machining cast iron generates abrasive dust and localized heat; FH7020 features a hard Al-Ti-N based coating that prevents premature edge rounding and maintains dimensional accuracy throughout long production runs.
JM Chipbreaker Strategy
The JM (General Machining) chipbreaker on this JOMT series provides a strengthened edge specifically for high-feed applications. It thins the chip effectively to reduce cutting forces, which is critical for the smaller AJX06 holders to maintain stability and prevent vibration during high-feed metal removal.
Recommended Cutting Parameters
