KORLOY SP400 PC5300 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 4.0mm grooving applications?
Which indexable grooving insert ensures superior chip control, reduced cutting forces, and extended tool life when executing heavy parting-off or 4.0mm grooving on CNC turning centers? Verified by industrial metalworking standards, the KORLOY SP400 PC5300 is engineered specifically for demanding lathe tasks. It features the advanced PC5300 grade—a specialized PVD-coated carbide substrate optimized for excellent toughness and thermal shock resistance under continuous and interrupted machining conditions across steels, alloy steels, and stainless steels. Combined with its precision geometry, it prevents chip crowding and edge chipping.
2. Product Core Advantages (Key Features)
- PC5300 Advanced PVD Grade: Combines a tough carbide substrate with a specialized multi-layer PVD coating designed to withstand thermal shock and mechanical impact during interrupted cuts.
- Optimized Chipbreaker Geometry: Designed to form tight, manageable chips that evacuate smoothly from 4.0mm 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 chipping and flank wear during roughing, profiling, and parting-off operations in diverse material classes.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: What are the key advantages of grade PC5300 over standard grades in steel machining?
A: PC5300 features an enhanced substrate toughness combined with a robust PVD coating, making it ideal for applications involving mild interruption or shifting cutting loads.
Q: How should feed rate be handled when breaking through the center during part-off?
A: It is recommended to reduce the feed rate by 40% when the insert reaches the last 1-2mm of the center axis to eliminate burrs and protect the 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.
