The Original Korloy MGMN300-02-R PC5300 is a versatile and high-precision 3.0mm Right-Hand Profiling and Grooving Insert. Engineered for multi-material machining, this insert features the industry-leading PC5300 PVD coating, providing exceptional performance in Stainless Steel, Alloy Steel, and High-Temp Alloys. The sharp 0.2mm corner radius (R0.2) ensures pinpoint accuracy for complex contours, making it a favorite for CNC machinists requiring a balance of toughness and surface finish.
The All-Rounder's Choice: PC5300 is designed to handle the toughest conditions. Its fine-grained substrate and advanced PVD layer offer high resistance to thermal shock and chipping, which is crucial during the lateral turning forces of profiling operations.

Machinist Tip: PC5300 vs. PC9030 for 3mm Grooving
Both are high-quality PVD grades, but the application environment determines the winner:
The Universal Tough-Guy. Best for general-purpose machining where you switch between steel and stainless often. It has better resistance to vibration and edge chipping.
The Stainless Specialist. Optimized specifically for high-speed finishing of stainless steel. It is slightly harder but less versatile than PC5300.

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.
