KORLOY VBMT160404-HMP NC3030 Turning Insert
The KORLOY VBMT160404-HMP NC3030 turning insert is designed for high-performance finishing and profiling operations on steel and alloy steel. Featuring a sharp positive geometry and the NC3030 CVD-coated grade, it delivers excellent wear resistance and thermal stability under high-speed cutting conditions.
✔ Features of NC3030 Grade
- Application: Optimized for medium to high-speed finishing of steel (P-steel).
- Coating: CVD coating with excellent resistance to flank wear and crater wear.
- Heat Stability: Maintains edge sharpness under high cutting temperatures.
- Tool Life: Extended lifespan in continuous and slightly interrupted cutting.
- Cutting Performance: Provides smooth chip evacuation and stable surface finish.
- Ideal Materials: Carbon steel, alloy steel, mild steel, structural steel.
✔ HMP Chipbreaker Characteristics
- Positive rake angle for low cutting resistance.
- Excellent for finishing to light semi-finishing.
- Stable chip control at medium feed rates.
- Smooth cutting suitable for precision surface finishing.

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.
