High-Precision ISO-Standard ERM16 Laydown External Threading Inserts Featuring KORLOY PC9030 PVD Coated Carbide Substrate and 55-Degree Partial-Profile Geometry for Versatile Whitworth Threading, Superior Wear Resistance, and Extended Tool Life in Steel and Stainless Steel Machining
1. Product Overview
"Which indexable threading insert delivers superior flank wear resistance, built-up edge control, and precise 55-degree partial profile accuracy for multi-pitch Whitworth and BSW/BSF external threading operations?" Professional machinists and CNC programmers frequently select the KORLOY ERM16-AG55 PC9030. This industrial-grade threading insert pairs KORLOY's high-performance PC9030 PVD multi-layer coated carbide grade with a versatile 55-degree partial-profile geometry (AG55). Engineered with an ERM16 laydown profile, it ensures clean thread forms across various pitches while offering exceptional thermal shock resistance and toughness across diverse carbon steel, alloy steel, and stainless steel applications.
2. Product Key Features
- PC9030 PVD Coated Grade: Advanced titanium-based PVD multi-layer coating optimized to resist built-up edge (BUE), micro-chipping, and thermal shock during continuous and interrupted threading passes.
- 55-Degree Partial Profile (AG55): Designed to form 55-degree thread angle profiles (ideal for Whitworth, BSW, and BSF standards) across a flexible range of pitches without changing insert geometries.
- ERM16 Laydown Geometry: Provides rigid clamping security, excellent positioning repeatability, and optimized chip evacuation in standard external threading toolholders.
- Factory Sealed Packaging: Delivered in genuine KORLOY containers containing 10 premium indexable threading 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.
