KORLOY SP200 PC9030 Indexable Grooving & Cut-Off Inserts (10pcs/box)
High-Performance PVD Coated Carbide Inserts for CNC Lathe Grooving, Parting-Off, and Precision Turning Applications
1. Product Overview: Which insert is best for high-stability CNC lathe parting and 2.0mm grooving applications?
Which indexable grooving insert ensures superior chip control, reduced cutting forces, and extended tool life when executing heavy parting-off or 2.0mm grooving on CNC turning centers? Verified by industrial metalworking standards, the KORLOY SP200 PC9030 is engineered specifically for demanding lathe tasks. It features the advanced PC9030 grade—a specialized multi-layer PVD-coated carbide substrate optimized for high wear resistance, thermal stability, and edge toughness under continuous machining conditions across carbon steels, stainless steels, and alloy steels. Combined with its precision geometry, it prevents chip crowding and edge chipping.
2. Product Core Advantages (Key Features)
- PC9030 Advanced PVD Grade: Combines a tough carbide substrate with a robust multi-layer PVD coating designed to withstand high cutting speeds and prolonged thermal loads in steel and stainless turning.
- Optimized Chipbreaker Geometry: Designed to form tight, manageable chips that evacuate smoothly from 2.0mm wide grooves without scratching workpiece sidewalls.
- Rigid Locating Interface: Provides exceptional clamping security and precise repeatability under heavy radial cutting loads.
- High Edge Toughness: Resists thermal cracking and flank wear during uninterrupted roughing, profiling, and parting operations.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: What are the primary benefits of the PC9030 PVD grade in stainless and alloy steel parting operations?
A: PC9030 features a specialized PVD multi-layer coating optimized for high fracture toughness and resistance to thermal shock, allowing stable performance in both steel and stainless steel applications.
Q: How should feed rate be handled when breaking through the center during part-off with a 2mm insert?
A: It is recommended to reduce the feed rate by 40% when the insert reaches the last 1mm of the center axis to eliminate burrs and protect the narrow insert tip from impact shock.
Q: How many inserts are packaged per box?
A: Each factory-sealed box contains 10 indexable inserts.
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.
