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).

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.
