The Original Korloy CCMT09T304-C25 CN2000 (ANSI: CCMT 32.1) is a high-performance Cermet (Ceramic-Metal) insert, engineered specifically for high-speed finishing operations where surface integrity is critical. Unlike standard carbide, the CN2000 grade maintains its hardness at much higher temperatures, preventing material adhesion and ensuring a mirror-like surface finish on carbon steels, alloy steels, and stainless steels. It is the gold standard for maintaining tight tolerances in long-run production.
Machinist's Tip: Cermet inserts thrive in high-speed, continuous cuts. If you are experiencing "built-up edge" with carbide, switching to CN2000 will dramatically improve your surface brightness.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT09T304-C25 |
| ANSI Code | CCMT 32.1 |
| Grade | CN2000 (Finishing Cermet) |
| Chipbreaker | C25 (Precision Chip Control) |
Core Performance Benefits:
- Exceptional Surface Finish: Eliminates the need for secondary grinding. Ideal for aesthetic parts and high-precision seals.
- Chemical Stability: Cermet has a low affinity for metal, which means no "welding" or sticking of the workpiece to the tool edge.
- High Red-Hardness: Allows for significantly higher cutting speeds (Vc) than traditional carbide, boosting your daily output.
- Consistent Tolerance: Resists crater and flank wear, ensuring the diameter of your parts stays consistent throughout the shift.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (1018/1045) | 200 - 400 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.2 mm |
| Stainless Steel (Precision) | 150 - 300 m/min | 0.04 - 0.12 mm/rev | 0.1 - 0.8 mm |
Compatible Tool Holders:
For mirror finishing, tool rigidity is paramount. Use these SCLCR/L type holders:
- External Turning: SCLCR1212H09 / SCLCR1616H09 / SCLCR2020K09
- Internal Boring Bars: S12M-SCLCR09 / S16Q-SCLCR09 / S20R-SCLCR09
The Cermet Advantage: CN2000 vs. PC5300
Is Cermet right for your application?
Best for high-speed finishing and achieving maximum brightness. Use in stable, continuous cuts only.
Best for roughing, semi-finishing, or interrupted cuts. More durable but lacks the surface shine of Cermet.
Warning: Cermet is brittle. Avoid using it on manual lathes with excessive play or on parts with heavy cross-holes/interruptions.
Packaging: 10 pieces per box.
