Korloy ERM16-1.0ISO PC9030 Metric External Threading Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy ERM16-1.0ISO PC9030 is a high-precision Full Profile External Threading Insert designed for producing perfect 1.0mm pitch metric threads. Unlike partial profile inserts, this full profile design cuts the complete thread form—including the crest—ensuring maximum dimensional accuracy and a burr-free finish. Coated with the premium PC9030 PVD grade, it offers exceptional toughness and resistance to built-up edge, making it the industry standard for machining Stainless Steel (M), Carbon Steel (P), and Exotic Alloys (S).
Precision Every Pass: The ERM (External Right-Hand) geometry is optimized for stable threading cycles. By using the PC9030 grade, operators can achieve longer tool life in gummy materials like 304 or 316 stainless steel without sacrificing thread quality.

The Threading Expert: PC9030 vs. PC5300
Korloy offers two main PVD grades for threading—here is how to choose:
The specialist for Stainless Steel and Tough Alloys. It has a sharper edge and a smoother coating to prevent the "sticky" chips of stainless from tearing the thread crest.
The best choice for Universal Steel Turning and interrupted cuts. It is more robust and offers higher impact resistance for rougher workpieces.
Machinist's Pro Tip: For the best thread finish, ensure your last pass is a "spring pass" (a pass at the same depth as the previous one) to clean up any residual deflection.
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.
