The Original Korloy CCMT09T304-C25 PC9030 (ANSI: CCMT 32.1) is a specialized tool designed for ultra-precision finishing of stainless steel. While standard inserts focus on general turning, the C25 chipbreaker features a high-positive rake angle and an extra-sharp edge specifically engineered to "slice" through gummy materials like 304 and 316L. Paired with the premium PC9030 PVD coating, it delivers superior surface gloss and exceptional dimensional stability.
Precision Specialist: The C25 chipbreaker is designed for lighter depths of cut than the HMP series, making it the perfect choice for high-precision boring and medical-grade component manufacturing.

Core Performance Benefits:
- Ultra-Sharp Cutting Edge: The C25 geometry minimizes radial cutting forces, effectively preventing vibration (chatter) in small-diameter boring or long-reach applications.
- Superior Anti-Adhesion: PC9030 PVD coating prevents "stickiness" in stainless steel, ensuring the edge remains sharp and the workpiece remains burr-free.
- Exceptional Surface Ra: Achieve mirror-like finishes directly on the machine, reducing or eliminating the need for post-process polishing.
- Stable Tool Life: High chemical stability makes it resistant to crater wear, even at higher surface speeds.
Recommended Cutting Parameters:

Finishing Pro-Tip: C25 vs. HMP Chipbreaker
Choosing the right geometry for your project:
A great versatile choice for semi-finishing to finishing. Stronger edge for general stainless work.
Sharper rake angle for super-fine finishing. Best for preventing chatter and achieving the highest gloss.
Machinist's Tip: If your R0.4 HMP insert is creating too much tool pressure and causing vibration in thin walls, switch to the C25 chipbreaker for a cleaner cut.
Packaging: 10 pieces per box.
