Korloy TCMT110204-HMP PC9030 Stainless Steel Turning Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy TCMT110204-HMP PC9030 is a high-performance Triangular Indexable Turning Insert engineered specifically for the challenges of machining Stainless Steel (M-Group) and High-Temperature Alloys. The PC9030 PVD Grade is Korloy's premier solution for preventing "built-up edge" and notch wear, while the HMP (Medium-Finish) Chipbreaker is optimized for medium-to-finishing applications, ensuring stable chip evacuation even in gummy materials.
The Stainless Expert: PC9030 is specifically formulated for the toughness required in interrupted cuts and low-to-medium speed stainless steel turning. It provides a significant leap in tool life when machining 304, 316, and Duplex stainless steels.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Designation | TCMT110204-HMP |
| Corner Radius (r) | 0.4 mm |
| Grade | PC9030 (Premium PVD for Stainless) |
| Chipbreaker | HMP (Medium-Finishing) |
Core Performance Benefits:
- Exceptional Heat Resistance: Advanced PVD coating maintains edge hardness under the high thermal loads typical of stainless steel machining.
- HMP Geometry: Features a positive rake angle that reduces cutting resistance, preventing work hardening of the workpiece surface.
- Anti-Adhesion Coating: The ultra-smooth surface prevents gummy stainless steel chips from welding to the cutting edge.
- Edge Reliability: High toughness substrate makes it ideal for internal boring bars where vibration can be an issue.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.08 - 0.22 mm/rev | 0.5 - 2.5 mm |
| Duplex Stainless Steel | 50 - 120 m/min | 0.08 - 0.18 mm/rev | 0.5 - 2.0 mm |
| Heat Resistant Alloys | 30 - 80 m/min | 0.05 - 0.15 mm/rev | 0.3 - 1.5 mm |
Compatible Tooling Systems:
Precision matched for 11-sized triangular holders:
- Internal Boring Bars: S12M-STUCR11 / S16Q-STUCR11 / S20R-STUCR11

Machinist Tip: PC9030 vs PC5300
Choosing the right PVD grade for your project:
Unmatched in M-Group. Engineered strictly for stainless steel. It has a smoother coating surface that effectively prevents adhesion. If you only machine stainless, this is your best choice.
The Generalist. Use PC5300 if you need to switch between steel, stainless, and cast iron frequently. It is tougher for heavy interruptions but not as chemical-resistant as PC9030 for high-end stainless finishing.
Pro Advice: When boring stainless steel with TCMT11, avoid using very low feed rates. Stainless steel work-hardens quickly; you need to ensure the cutting edge is cutting "under" the hard surface layer generated by the previous pass.
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.
