Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN600-M PC9030 is a powerhouse 6.0mm Double-Ended Grooving Insert designed for Extreme Stainless Steel Machining. Engineered with the high-performance PC9030 PVD grade, this insert is the industry's answer to large-scale grooving challenges in austenitic stainless steels (304/316) and heat-resistant superalloys. The massive 6.0mm width provides unmatched rigidity, ensuring the tool remains stable during high-torque radial plunging where smaller inserts would vibrate or fail.
Built for Heavy Industry: MGMN600-M excels in heavy-duty applications where productivity and tool security are critical. The PC9030 grade’s advanced PVD coating acts as a thermal barrier, preventing edge deformation under the intense heat of 6.0mm wide cuts.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN600-M |
| Insert Width (w) | 6.0 mm (+/- 0.05) |
| Grade | PC9030 (Premium Stainless Steel Specialist) |
| Chipbreaker | -M (Stable Heavy-Duty Geometry) |
Core Performance Benefits:
- Maximum Edge Stability: The wide 6.0mm profile handles extreme cutting pressure without deflection.
- Superior Thermal Management: PC9030's nano-PVD coating is designed to resist the high-temperature chemical reactions of nickel-rich alloys.
- Anti-Adhesion Edge: Drastically reduces Built-Up Edge (BUE), a major cause of failure in large-scale stainless machining.
- Engineered Chip Breaking: The -M geometry effectively curls 6mm wide chips, ensuring they don't clog the groove.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (304 / 316) | 70 - 130 m/min | 0.15 - 0.35 mm/rev |
| Duplex Stainless Steel | 45 - 80 m/min | 0.12 - 0.28 mm/rev |
| Nickel Alloys / Titanium | 25 - 55 m/min | 0.10 - 0.22 mm/rev |
Compatible Tool Holders:
Due to the high torque of 6.0mm grooving, we recommend heavy-duty tool holders:
- External Holders: MGEHR 2525-6 / 3232-6 / 4040-6
The 6mm Decision: PC9030 vs. PC5300
When choosing a grade for 6.0mm wide cuts in tough materials, consider the coating technology:
The Stainless Specialist. Optimized specifically for M (Stainless) and S (Alloys) groups. Use this for 304/316/Duplex where sticking and heat are the primary enemies.
The General Purpose Giant. Tougher substrate for interrupted cuts in general steel (P group). While highly versatile, it doesn't match the chemical resistance of PC9030 in gummy stainless.
Machinist's Pro Tip: For MGMN600-M PC9030, at 6mm width, the chip-load is immense. If your machine shows power fluctuation, reduce the feed rate ($f$) slightly but increase the coolant pressure. This ensures the wide 6.0mm chip doesn't rub against the side-walls of the groove.
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.
