The Original Korloy SCMT09T304-HMP PC9030 is a high-precision Square (7° Positive) Turning Insert, specifically engineered for the complexities of Stainless Steel (M-Group) machining. Featuring the advanced PC9030 PVD Coating, this insert offers a specialized TiAlN layer that provides exceptional resistance to adhesive wear and built-up edge (BUE). The -HMP (Highly Medium Performer) chipbreaker is meticulously designed for semi-finishing, providing reliable chip evacuation in "gummy" materials like 304, 316, and heat-resistant alloys.
Expertly Crafted for Stainless: Stainless steel is prone to work-hardening and excessive heat. The PC9030 grade features a high-toughness substrate and a ultra-smooth PVD coating that allows for lower cutting temperatures and prevents the workpiece material from welding to the cutting edge.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | SCMT09T304-HMP |
| Inscribed Circle (IC) | 9.525 mm |
| Thickness / Corner Radius | 3.97 mm / 0.4 mm |

Core Performance Benefits:
- Anti-Stick Performance: Advanced PVD coating technology drastically reduces friction, ideal for austenitic stainless steels.
- Precise Chip Control: The HMP geometry features a wave-form rake face that successfully breaks chips at medium feed rates, preventing "stringing."
- Excellent Edge Sharpness: The positive geometry ensures low cutting forces, which is critical for maintaining accuracy in internal boring.
- Superior Toughness: Resists thermal cracking even in interrupted cuts with high-pressure coolant.
Recommended Cutting Parameters (Stainless Steel):
| Material Type | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| 304 / 316 Stainless | 100 - 180 m/min | 0.08 - 0.25 mm/rev | 0.5 - 2.5 mm |
| 400 Series / Martensitic | 120 - 220 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.0 mm |
| Duplex Stainless | 50 - 100 m/min | 0.08 - 0.20 mm/rev | 0.5 - 2.0 mm |

Machinist Tip: PC9030 vs PC5300
Selecting the best PVD grade for your SCMT09 inserts:
Pure Stainless Success. Specifically optimized for Grade 300 series. If your main job is stainless steel production, PC9030 offers the longest life and best anti-sticking properties.
Mixed Material Flexibility. Choose PC5300 if you process both Steel and Stainless in the same machine. It is tougher for interrupted cuts but wears faster in high-heat stainless applications.
Pro Advice: When boring stainless steel with the SCMT09T304-HMP, use high-pressure coolant directed at the tool tip. This not only cools the edge but helps the HMP geometry "shoot" the chips out of the bore, preventing recutting.
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.
