8. Frequently Asked Questions (FAQ)
Q: Why is the H01 grade uncoated when machining aluminum alloys?
A: Uncoated micro-grain carbide provides an exceptionally sharp cutting edge and eliminates coating flaking, preventing aluminum from welding to the rake face and causing built-up edge (BUE).
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable turning inserts, securely packed to prevent edge damage during transit.
Q: What is the main benefit of the -HA chipbreaker?
A: The -HA breaker features a highly polished, sharp geometry designed specifically to reduce cutting forces and deliver mirror-like surface finishes on soft non-ferrous materials.

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.
