Korloy CCMT060204-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 CCMT060204-HMP PC9030 is a high-performance carbide insert specifically engineered for the stable finishing and semi-finishing of stainless steel. Featuring an advanced PVD coating, the PC9030 grade excels at resisting built-up edge (BUE) and thermal cracking. With a standard 0.4mm nose radius, it provides the perfect balance of edge toughness and superior surface finish for small-scale precision turning.

Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT060204-HMP |
| Grade | PC9030 (PVD Coated for Stainless) |
| Nose Radius | 0.4 mm (Balanced Finishing) |
| Chipbreaker | HMP (High Precision / Medium-Duty) |
Core Performance Benefits:
- Optimized for Stainless Steel: The ultra-smooth PVD coating prevents material adhesion, ensuring long tool life in austenitic stainless steels like 304 and 316.
- Stable Edge Strength: The 0.4mm radius offers more durability than 0.2mm, making it ideal for slightly higher feed rates and varying depths of cut.
- Superior Chip Control: The HMP geometry ensures efficient chip breaking even at low feed rates, preventing long swarf from tangling in small bores.
- Excellent Heat Resistance: Maintains hardness at high temperatures, allowing for consistent performance in high-speed machining.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 180 m/min | 0.05 - 0.15 mm/rev | 0.5 - 2.5 mm |
| High-Temp Alloys | 30 - 60 m/min | 0.04 - 0.12 mm/rev | 0.3 - 1.5 mm |
Compatible Tool Holders:
This CCMT 06 insert is a standard fit for SCLCR/L type tool holders. Ensure a rigid setup for best results:
- Boring Bars (Internal): S08K-SCLCR06 / S10K-SCLCR06 / S12M-SCLCR06
- External Holders: SCLCR1010H06 / SCLCR1212H06 / SCLCR1616H06
Stainless Steel Pro-Tip: PC9030 vs. PC5300
Choosing the right Korloy grade for your stainless project:
Best for finishing, continuous cuts, and internal boring. Provides the best surface smoothness.
Best for semi-roughing, interrupted cuts, or unstable setups. More resistant to breakage.
Machinist's Tip: For stainless steel, always use high-pressure coolant to prevent heat-induced work hardening and extend tool life.
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.
