KORLOY NFTG11252R 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 NFTG11252R 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 0.12mm and tapering down to 0.02mm 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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
