Korloy MGMN500-M PC9030 5mm Double-Ended Stainless Steel Grooving Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN500-M PC9030 is a heavy-duty 5.0mm Double-Ended Grooving Insert engineered for Stainless Steel and Heat-Resistant Alloys. Utilizing the premium PC9030 PVD grade, this insert is the ultimate choice for managing the thermal and mechanical stresses of machining large-diameter components made of 304/316 stainless, Duplex steel, and Inconel. The 5.0mm width provides massive tool rigidity, making it suitable for deep radial plunging where thinner inserts might fail due to vibration or deflection.
Heavy-Duty Precision: MGMN500-M is optimized for large-scale industrial applications. The PC9030's ultra-tough PVD coating resists built-up edge and thermal cracking, ensuring consistent surface quality and long tool life in the most demanding stainless steel environments.

Core Performance Benefits:
- Extreme Heat Resistance: The specialized PVD coating maintains its hardness even at the high temperatures generated by 5.0mm wide cuts.
- Maximum Tool Rigidity: Massive 5.0mm profile allows for aggressive feed rates without tool breakage.
- Anti-Adhesion Technology: Dramatically reduces material welding (Built-Up Edge) common in 300-series stainless steel.
- Reliable Chip Breaking: The -M chipbreaker ensures that even wide, tough stainless steel chips are curled and evacuated efficiently.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Austenitic Stainless (304/316) | 80 - 140 m/min | 0.12 - 0.30 mm/rev |
| Duplex Stainless Steel | 50 - 90 m/min | 0.10 - 0.25 mm/rev |
| Titanium & Nickel Alloys | 30 - 60 m/min | 0.08 - 0.18 mm/rev |
Compatible Tool Holders:
To support the high cutting forces of a 5.0mm insert, we recommend heavy-duty MGEHR/L holders:
- External Holders: MGEHR 2525-5 / 3232-5 / 4040-5
Stainless Tooling Tip: PC9030 vs. PC5300
Selecting the right grade for a 5.0mm wide stainless steel groove is key to your profit-per-part:
The Stainless Specialist. Engineered for the chemical challenges of M-group materials. Its coating prevents material welding better than any other grade, vital for 5.0mm wide chips.
The Universal Powerhouse. Better for heavy interrupted cuts in general steel. While it can handle stainless, it may experience more crater wear at the high feed rates used with 5.0mm inserts.
Machinist's Pro Tip: For MGMN500-M PC9030, when machining 316 stainless, the chip can get very hot. Use a "peck-cycle" to break the chip and allow coolant to reach the insert's center. This prevents thermal deformation of the 5.0mm wide cutting edge.
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.
