Korloy CCMT060202-HMP PC9030 Precision Stainless Steel Turning Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy CCMT060202-HMP PC9030 is a premium micro-grain carbide insert specifically engineered for precision finishing of stainless steel. Featuring an advanced PVD coating, the PC9030 grade excels at preventing built-up edge (BUE) and maintaining sharp cutting performance under high-heat conditions. Its compact 06-size and ultra-sharp 0.2mm nose radius make it the perfect choice for intricate internal boring and small-diameter turning.

Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT060202-HMP |
| Grade | PC9030 (Stainless Steel Specialist) |
| Nose Radius | 0.2 mm (Ultra-Precision Finishing) |
| Coating | PVD (Heat Resistant) |
Core Performance Benefits:
- Anti-Adhesion Technology: The smooth PVD coating reduces friction, preventing stainless steel from "sticking" to the edge and causing chipping.
- Mirror-Like Finish: The R0.2 radius provides exceptionally low cutting resistance, eliminating chatter marks on thin-walled or small parts.
- Superior Heat Resistance: Maintains hardness at the cutting edge during dry or wet machining of austenitic stainless steels (304, 316).
- Enhanced Edge Sharpness: Unlike CVD coated inserts, PVD allows for a much sharper edge, essential for preventing work-hardening in stainless.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless 304 / 316 | 80 - 180 m/min | 0.03 - 0.12 mm/rev | 0.1 - 1.2 mm |
| High-Temp Alloys | 30 - 70 m/min | 0.03 - 0.10 mm/rev | 0.1 - 1.0 mm |

Stainless Steel Grade Tip: PC9030 vs. PC5300
Which Korloy grade fits your stainless application?
Best for high-precision finishing, small diameters, and boring. Excellent surface quality.
Best for general purpose turning and interrupted cuts. More robust in unstable setups.
Machinist's Tip: For stainless steel, always use plenty of high-pressure coolant with PC9030 to maximize tool life and surface finish.
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.
