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:

- 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.
