The Original Korloy MGMN500-M PC215K is a heavy-duty 5.0mm Double-Ended Grooving Insert specifically engineered for High-Toughness Cast Iron Machining. Utilizing the premier PC215K PVD grade, this insert is the professional solution for Gray Cast Iron (GG) and Ductile Iron (GGG) in demanding environments. While CVD grades focus on high-speed continuous wear, the PC215K excels in edge protection, making it ideal for 5.0mm wide cuts involving interrupted surfaces, sand inclusions, or abrasive casting skins.
Rigidity Meets Toughness: At 5.0mm width, the MGMN500-M provides massive structural strength for deep radial plunging. The PC215K's toughened PVD coating prevents micro-chipping, ensuring reliable performance in heavy-duty iron components where stability is paramount.
Technical Specifications:

Cast Iron Expert Tip: PC215K vs. NC6210
Korloy offers two paths for K-Group materials. Choosing the right one for your 5.0mm grooves is essential:
The Toughness Specialist. A PVD grade that offers superior edge integrity. Best for 5.0mm grooving where interrupted cuts or vibrations cause CVD inserts to chip prematurely.
The High-Speed Specialist. A CVD grade with thick alumina coatings. Best for continuous, high-volume roughing where pure abrasive wear at high speeds is the priority.
Machinist's Pro Tip: For MGMN500-M PC215K, given the wide 5.0mm contact area, ensure your machine spindle has enough torque. When grooving deep into cast iron, retract the tool slightly every 3-5mm to clear out abrasive iron dust and allow the PC215K edge to cool momentarily.
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.
