The Original Korloy SNMG120612-HS PC9030 is a heavy-duty Double-Sided Square Turning Insert engineered for large-scale Stainless Steel (M-Group) and Super Alloy applications. Designed for heavy industrial use, this insert combines the massive stability of the 1906 size with the ultra-efficient PC9030 PVD Grade. The -HS (High-Sharpness) chipbreaker is uniquely optimized for large inserts to reduce spindle load and prevent vibration during deep semi-finishing passes on large-diameter shafts and flanges.
Heavy-Duty Precision: When machining large stainless steel components, heat and vibration are your biggest enemies. The SNMG190612-HS features a 1.2mm radius for maximum edge strength and a razor-sharp geometry that slices through material, ensuring superior surface integrity on expensive workpieces.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | SNMG190612-HS |
| Corner Radius | 1.2 mm (High Feed & Heavy Load) |
| Insert Thickness | 6.35 mm (Heavy Duty) |
| Grade | PC9030 (Superior PVD for Heat Resistance) |
Core Performance Benefits:
- Substantial Edge Strength: The 1.2mm radius allows for heavy metal removal rates while maintaining a smooth finish on large surface areas.
- Vibration Control: The HS chipbreaker lowers the radial force, making it ideal for large parts with high length-to-diameter ratios.
- Anti-Welding PVD Coating: PC9030 grade is chemically inert, preventing the "gummy" stainless steel chips from sticking to the large cutting edge.
- 8 Usable Edges: Despite its heavy-duty size, this double-sided insert provides 8 cutting corners for maximum economic efficiency.
Recommended Cutting Parameters (Heavy Stainless):
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| 304 / 316 Stainless | 80 - 150 m/min | 0.25 - 0.50 mm/rev | 1.5 - 6.0 mm |
| Duplex / Super Duplex | 40 - 80 m/min | 0.20 - 0.40 mm/rev | 1.0 - 5.0 mm |
| Inconel / Monel | 20 - 45 m/min | 0.15 - 0.35 mm/rev | 1.0 - 4.0 mm |

Requires 19mm IC negative holders:
- External Heavy Turning: MSSNR 3232P19 / 4040R19
Machinist Tip: Scaling Up to SNMG1906
Why the 1906 size is different for Stainless Steel:
Heat Management. Large inserts like the 190612 generate massive heat. PC9030 is designed to keep the edge sharp even when the cutting zone turns red. The HS geometry ensures that heat is carried away by the chip, not the workpiece.
Always use a "Top Clamp" (PSSKNR) holder for 19mm inserts. The high cutting forces in stainless steel roughing require maximum clamping pressure to prevent the insert from shifting during the cut.
Pro Advice: When roughing large stainless forgings, if you encounter "crust" or "scale," consider a first pass with a lower feed rate to protect the HS sharp edge, then increase to full feed once you are in the clean material.
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.
