Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT09T302-HMP |
| Grade | PC9030 (PVD Specialist for Stainless) |
| Nose Radius | 0.2 mm (Ultra-Precision Finishing) |
| Chipbreaker | HMP (High Precision) |
Core Performance Benefits:
- Minimal Cutting Pressure: The R0.2 radius significantly reduces radial force, making it the best choice for preventing chatter in long-reach boring or on thin-diameter parts.
- Exceptional Surface Quality: Achieves a mirror-like finish even on gummy materials like 304 and 316 stainless steel by slicing through fibers rather than rubbing.
- Advanced PVD Technology: The PC9030 coating is optimized to withstand the thermal shocks of interrupted cuts while preventing Built-Up Edge (BUE).
- Precision Edge Sharpness: Unlike CVD inserts, this PVD grade maintains a razor-sharp edge, essential for clean cuts in high-precision aerospace and medical components.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 180 m/min | 0.04 - 0.12 mm/rev | 0.1 - 1.2 mm |
| Heat-Resistant Alloys | 30 - 70 m/min | 0.03 - 0.10 mm/rev | 0.1 - 1.0 mm |
Compatible Tool Holders:
For the best finishing results, use this CCMT 09 size insert with precision SCLCR/L tool holders:
- Boring Bars (Internal): S12M-SCLCR09 / S16Q-SCLCR09 / S20R-SCLCR09

Stainless Steel Pro-Tip: PC9030 vs. PC5300
Selecting the right grade for your stainless steel project:
Optimized for high-precision finishing and boring. Best surface finish and dimensional stability.
Better for semi-roughing, interrupted cuts, or when extra toughness is needed to prevent edge chipping.
Machinist's Tip: When using the R0.2 radius, ensure your machine has high spindle speeds available to maintain the recommended surface footage (Vc).
Packaging: 10 pieces per box.
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.
