The Original Korloy MGMN200-T PC5300 is a high-performance 2.0mm Double-Ended Grooving Insert engineered for universal steel machining and heavy-duty parting. Featuring the -T (Tough) chipbreaker, this insert is specifically reinforced to handle interrupted cuts and unstable machining environments where standard inserts might chip. The PC5300 PVD grade offers a perfect balance of hardness and impact resistance, making it the most versatile 2.0mm choice for general engineering workshops.
Maximum Edge Security: While the 2.0mm width minimizes material loss, the -T geometry ensures the cutting edge doesn't crumble under the shock of scale or cross-holes. It is the go-to insert for "troubleshooting" chipping issues in small-to-medium parts.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-T |
| Insert Width (w) | 2.0 mm (+/- 0.02) |
| Grade | PC5300 (Universal High-Toughness - PVD) |
| Key Benefit | Chipping Resistance in Interrupted Cuts |
Core Performance Benefits:
- Reinforced Cutting Edge: The -T geometry is built to withstand impact, making it ideal for grooving shafts with keyways or hex bolts.
- Sub-Micron PVD Coating: PC5300 grade provides heat resistance while maintaining the structural integrity of the carbide substrate.
- Economical 2.0mm Width: Saves material on every cut, especially vital when working with expensive alloy steels or stainless.
- Broad Material Range: Reliable performance across Carbon Steels (P), Alloy Steels, and Stainless Steels (M).
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Carbon Steel (P1-P3) | 100 - 180 m/min | 0.05 - 0.12 mm/rev |
| Alloy Steel / Tool Steel | 80 - 150 m/min | 0.04 - 0.10 mm/rev |
| Stainless Steel (General) | 70 - 130 m/min | 0.04 - 0.08 mm/rev |

- External Holders: MGEHR 1212-2 / 1616-2 / 2020-2 / 2525-2
The Tough Choice: MGMN200-T vs. MGMN200-G
When selecting your 2.0mm grooving insert, the chipbreaker is just as important as the grade:
The Impact Specialist. Features a stronger edge to prevent chipping. Best for interrupted cuts, pre-hardened materials, and heavy-duty parting operations.
The Precision Specialist. Sharper edge for lower cutting forces. Best for continuous cuts and where dimensional precision and surface finish are the top priority.
Machinist's Pro Tip: For MGMN200-T PC5300, if you are parting off toward the center of a bar, don't be afraid to keep the feed rate ($f$) consistent. The -T geometry is built to survive the sudden change in cutting force at the center.
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.
