The Original Korloy SNMG120404-HA PC9030 is a specialized Double-Sided Square Turning Insert that bridges the gap between high productivity and precision sharpness. By combining the 8-edged economy of the SNMG series with the ultra-sharp -HA geometry and PC9030 PVD Coating, this insert is the ultimate problem-solver for "gummy" Stainless Steels (304, 316L), Titanium, and Inconel. It is particularly effective for thin-walled parts or setups where vibration is a concern.
Sharpness Meets Durability: Traditionally, sharp "HA" geometries are uncoated for aluminum. However, this PC9030 version features a high-toughness PVD coating, allowing it to "shear" through tough stainless steel fibers instead of "pushing" them, drastically reducing work hardening and heat buildup.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | SNMG120404-HA |
| Corner Radius | 0.4 mm (Precision & Low Force) |
| Chipbreaker | -HA (High-Positive Sharp Edge) |
| Grade | PC9030 (Premium PVD for Difficult Materials) |
Core Performance Benefits:
- Reduced Cutting Pressure: The sharp -HA edge lowers radial forces, making it ideal for long, slender workpieces or thin-wall tubes.
- Superior Anti-Stick: The smooth PC9030 coating prevents built-up edge (BUE) when machining low-carbon stainless steels (304L/316L).
- Heat Resistance: The PVD layer acts as a thermal barrier, protecting the cutting edge during the high-heat generation of nickel-alloy machining.
- 8 Edges of Economy: Provides significantly lower cost-per-part than positive (SCMT/CCGT) inserts for difficult materials.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 80 - 160 m/min | 0.05 - 0.18 mm/rev | 0.2 - 2.0 mm |
| Titanium Alloys | 40 - 90 m/min | 0.08 - 0.20 mm/rev | 0.5 - 2.5 mm |
| Nickel-Based Alloys | 25 - 50 m/min | 0.05 - 0.15 mm/rev | 0.2 - 1.5 mm |

Machinist Tip: Why use HA for Stainless Steel?
Understanding the specific use-case for SNMG-HA PC9030:
Anti-Work Hardening. Some stainless steels harden the moment the tool touches them. The HA edge is so sharp it slices before the material can harden, making it perfect for finishing passes.
The Standard Choice. Use -GS for general stainless turning. Switch to -HA ONLY if you encounter chatter (vibration) or if the material is so gummy it's wrapping around the tool.
Pro Advice: For SNMG120404-HA PC9030, always use plenty of high-pressure coolant. The HA edge is sharp and thin; without proper cooling, the tip can wear faster than a standard GS edge in high-speed applications.
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.
