KORLOY NFTG14302R PC130 Indexable Threading Inserts (10pcs/box)
High-Precision PVD Coated Carbide Inserts for CNC Lathe External Thread Turning, Screw Cutting, and Profile Machining
1. Product Overview: Which insert is best for high-precision CNC lathe external thread turning applications?
Which indexable threading insert ensures exceptional dimensional accuracy, superior surface finish, and extended tool life when executing external thread turning on CNC turning centers? Verified by industrial metalworking standards, the KORLOY NFTG14302R PC130 is engineered specifically for demanding threading operations. It features the advanced PC130 grade—a specialized multi-layer PVD-coated carbide substrate optimized for high toughness, fracture resistance, and clean edge definition under continuous cutting conditions across alloy steels, carbon steels, and stainless steels. Combined with its precision ground profile geometry, it prevents micro-chipping and ensures accurate thread pitch replication.
2. Product Core Advantages (Key Features)
- PC130 Advanced PVD Grade: Combines a fine-grained, tough carbide substrate with a robust multi-layer PVD coating designed to maintain sharp cutting edges and resist built-up edge (BUE) during thread turning.
- Precision Ground Thread Profile: Engineered to deliver exact flank angles and root radiuses, ensuring full compliance with international thread standards.
- Rigid Locating Interface: Provides exceptional clamping security and precise indexing repeatability under multi-pass radial infeed loads.
- Superior Flank Wear Resistance: Resists abrasive flank wear and thermal cracking during multi-pass thread cutting operations.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: What are the main advantages of the PC130 PVD grade when machining alloy steel threads compared to uncoated carbide?
A: PC130 utilizes a specialized multi-layer PVD coating optimized for high thermal resistance and edge retention at high cutting speeds ($Vc$), resulting in extended tool longevity and superior thread surface finish.
Q: How many passes are typically recommended when cutting external threads with the NFTG series?
A: Multi-pass incremental infeed using decreasing depth increments (e.g., starting at 0.15mm and tapering down to 0.03mm for finish passes) is recommended to minimize cutting forces and protect the insert tip.
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.
