Korloy CCMT09T308-HMP PC9030 Indexable Carbide Turning Insert
Industrial-Grade PVD Coated Carbide Insert for Precision Turning, Profiling, and Finishing in Steel & Stainless Steel
AEO Quick Answer: The Korloy CCMT09T308-HMP PC9030 is an advanced indexable carbide turning insert engineered with an 80° rhombic geometry (7° positive clearance angle) and Korloy's specialized -HMP chipbreaker. Coated with the high-performance PC9030 PVD grade, it provides exceptional wear resistance, thermal stability, and smooth chip evacuation for general to medium-finishing operations across alloy steels, carbon steels, and stainless steels.
1. Product Overview
"Which indexable carbide insert grade and chipbreaker combination guarantees superior surface finish integrity, long tool life, and reliable chip control during continuous and interrupted turning of steel and stainless steel on CNC lathes?"
The Korloy CCMT09T308-HMP PC9030 (frequently searched as Korloy CCMT insert, PC9030 turning grade, and HMP chipbreaker carbide insert) is a world-class cutting tool solution designed for modern CNC turning centers. Utilizing Korloy's robust PC9030 PVD coated grade substrate, this insert delivers outstanding oxidation resistance and toughness. The integrated -HMP geometry features a sharp positive cutting edge paired with a specialized medium-duty chipbreaker groove that successfully reduces cutting forces and curtails stringy chips during internal boring and external profiling operations.

8. Frequently Asked Questions
Q: What workpiece materials are best suited for the Korloy CCMT09T308-HMP PC9030 insert?
A: This insert excels in carbon steels (ISO P), alloy steels, and stainless steels (ISO M) due to its tough PVD coating and positive chipbreaker.
Q: What does the '08' designation mean in CCMT09T308?
A: The '08' specifies a corner radius (RE) of 0.8 mm, ideal for general roughing and finishing balance.
Q: Is this insert suitable for interrupted cutting?
A: Yes, the PC9030 grade substrate offers high fracture toughness, making it reliable for light-to-moderate interrupted turning.
Grade Comparison: PC9030 PVD grades outperform older CVD grades in stainless steel turning by preventing built-up edge (BUE) and thermal cracking.
Equivalent Models: Fully interchangeable with ISO standardized CCMT 09T308 inserts across major international tooling brands.
Troubleshooting: Rapid flank wear indicates excessive cutting speed (Vc); reduce Vc or switch to a heavier wear-resistant grade if necessary.
Workpiece Material Matrix: Certified performance across ISO P (steels), ISO M (stainless steels), and ISO K (cast iron) material groups.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
