The Original Korloy CCMT060204-HMP PC5300 (ANSI Standard: CCMT 21.1) is a high-toughness, universal carbide insert engineered for the most demanding machining conditions. While other grades may chip during interrupted cuts or on hard-skinned materials, the PC5300 grade features a specialized sub-micron substrate and advanced PVD coating that excels in Stainless Steel, Steel, and Heat-Resistant Alloys. It is the ultimate "safety first" grade for any CNC shop.
Machinist's Choice: Facing vibration or interrupted cuts in stainless? PC5300 provides the edge security you need. For high-speed continuous finishing, consider the PC9030 Series.

Core Performance Benefits:
- Universal Application: One grade for multiple materials (M-Stainless, P-Steel, S-Exotic Alloys), reducing your inventory costs.
- Extreme Toughness: Specialized grain structure prevents sudden edge breakage during interrupted cuts or when machining parts with uneven surfaces.
- Enhanced S-Coating: The latest PVD technology provides a smooth surface that reduces friction and prevents work-hardening in stainless steel.
- HMP Precision Geometry: The HMP chipbreaker ensures stable chip control across a wide range of feed rates, especially in small-diameter boring.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |

Grade Battle: PC5300 vs. PC9030
Which Korloy grade is right for your job?
Best for interrupted cuts, unstable machines, rougher surfaces, and general-purpose steel machining.
Best for continuous finishing in stainless steel where mirror-like surface quality is the priority.
Machinist's Tip: If your current insert keeps chipping on the first pass, switch to PC5300. Its superior impact resistance is a life-saver for unstable setups.
Packaging: 10 pieces per box.
