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.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
