Korloy ERM16-2.0ISO PC9030 Metric External Threading Insert, 2.0 Pitch (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy ERM16-2.0ISO PC9030 is a heavy-duty Full Profile External Threading Insert designed for 2.0mm pitch metric ISO threads. This insert is engineered to cut the complete thread profile—including the crest—resulting in a perfectly finished thread with no secondary deburring required. Utilizing Korloy's flagship PC9030 PVD grade, it offers a superior combination of substrate toughness and a high-lubricity coating, making it the top choice for threading Stainless Steel (M), Carbon Steel (P), and Hardened Alloys (S).
Superior Depth Control: Machining a 2.0mm pitch requires significant material removal per pass. The ERM16-2.0ISO is reinforced to handle the higher cutting forces, while the PC9030 coating prevents the "tearing" and "smearing" often seen in 304/316 stainless steel threads.
Technical Specifications:

Core Performance Benefits:
- Complete Form Cutting: Precisely forms the thread crest, maintaining strict outer diameter tolerances for M14, M16, and larger metric threads.
- Advanced PVD Coating: The PC9030 grade features a smooth, nanostructured coating that reduces friction and prevents heat buildup during deep threading passes.
- Exceptional Edge Stability: Resists micro-chipping even when machining work-hardened stainless steel or tough alloy steels.
- Reduced Tool Pressure: Optimized rake angle allows for cleaner cuts, reducing the risk of thread vibration and chatter.

The 2.0mm Pitch Challenge: PC9030 vs. PC5300
When machining deep threads like 2.0 pitch, grade selection is critical:
Best for Precision & Finish. In stainless steel, PC9030 ensures the thread profile remains sharp and smooth. It excels in minimizing friction-induced heat in deeper threads.
Best for Interrupted Cuts. If your workpiece is a hex bar or has cross-holes, PC5300's higher impact toughness will protect the tool from chipping better than any other grade.
Machinist's Pro Tip: For 2.0 ISO threads, always use plenty of high-quality cutting oil or coolant. Given the increased contact area of a 2.0mm pitch, cooling the insert tip is vital to prevent premature wear.
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.
