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.
