The Original Korloy ERM16-1.5ISO PC9030 is a premium Full Profile External Threading Insert optimized for 1.5mm pitch metric ISO threads. Unlike partial profile inserts, this full profile tool cuts the entire thread form, including the crest, ensuring perfect thread height and a burr-free finish every time. The PC9030 grade, a high-toughness PVD coated carbide, is specifically engineered to handle the thermal and chemical challenges of machining Stainless Steel (M), Carbon Steel (P), and Super Alloys (S).
Standard Pitch Mastery: The 1.5mm pitch is the "workhorse" of metric threading (found in M10x1.5, M12x1.5, etc.). By using the PC9030 grade, you eliminate the common problem of "tearing" the thread surface in gummy materials like 304 stainless steel, resulting in aerospace-grade thread quality.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | ERM16-1.5ISO |
| Thread Standard | Metric ISO (Full Profile) |
| Pitch | 1.5 mm |
| Grade | PC9030 (Premium PVD) |
Core Performance Benefits:
- Precision Thread Profile: Full profile geometry ensures 100% compliance with ISO standards, perfect for parts requiring GO/NO-GO gauge certification.
- PC9030 PVD Coating: Features a nano-structured layer that resists oxidation and prevents "Built-up Edge" (BUE) on stainless steel.
- Edge Sharpness: Unlike CVD grades, this PVD insert maintains a razor-sharp edge, reducing cutting pressure and preventing thread distortion.
- Total Thread Control: The ERM geometry is designed for stable chip formation during the multiple passes required for threading.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Recommended Passes |

| Stainless (304/316) | 70 - 140 m/min | 8 - 12 Passes |
| Carbon Steel (P) | 90 - 170 m/min | 6 - 10 Passes |
| Alloy Steel (Hardened) | 50 - 110 m/min | 10 - 14 Passes |

Machinist's Tip: PC9030 vs. PC5300 for Threading
Korloy's two most popular PVD grades for threads compared:
The Stainless Steel Specialist. Use this if you are machining 300-series stainless, titanium, or if you notice thread "tearing." It has a smoother coating surface to reduce friction.
The Universal Choice for carbon and alloy steels. If your main priority is edge toughness in interrupted cuts or high-tensile steels, PC5300 is the standard choice.
Pro-Tip: When threading 1.5mm pitch, ensure your threading cycle uses a modified flank inflow (29° or 29.5° angle) to ensure chips only flow from one side of the insert, preventing tool damage.
Packaging: 10 pieces per box.
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.
