The Original Korloy MGMN200-G PC9030 is a high-precision 2.0mm Double-Ended Grooving Insert engineered specifically for the challenges of Stainless Steel and Exotic Alloys. Machining stainless steel often leads to rapid heat buildup and material adhesion; the PC9030 PVD grade addresses this with a specialized TiAlN coating that offers a low friction coefficient and superior thermal stability. The 2.0mm width is the industry standard for general parting-off, providing excellent rigidity while minimizing kerf loss.
Anti-Stick Technology: The PC9030 grade is world-renowned for its anti-welding properties. It effectively prevents the "built-up edge" (BUE) that typically ruins surface finish and snaps tool tips when machining gummy materials like 304 or 316 stainless steel.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-G |
| Insert Width (w) | 2.0 mm |
| Grade | PC9030 (Ultra-Fine PVD Coating) |
| Target Material | Stainless Steel / HRSA |
Core Performance Benefits:
- Excellent Surface Finish: The razor-sharp edge of the PVD-coated MGMN200-G reduces cutting pressure, resulting in mirror-like finishes on stainless parts.
- Heat Resistance: Designed to withstand the high temperatures generated in the narrow 2mm slot without losing edge hardness.
- Optimized Chip Control: The -G (General) chipbreaker effectively narrows and curls chips for smooth evacuation in deep grooving operations.
- Double-Ended Efficiency: Two usable cutting edges provide a cost-effective solution for high-volume production.
Recommended Cutting Parameters:
| Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (304/316) | 90 - 160 m/min | 0.05 - 0.12 mm/rev |
| Titanium Alloys | 40 - 80 m/min | 0.04 - 0.10 mm/rev |
| Mild/Low Carbon Steel | 110 - 190 m/min | 0.05 - 0.15 mm/rev |

- External Holders: MGEHR 1212-2 / 1616-2 / 2020-2 / 2525-2
Machinist's Guide: PC9030 vs. NC3120
Choosing the right coating for your 2mm grooves is critical for tool life:
The Stainless Choice. PVD coating is thinner and sharper. Use for all stainless steels, titanium, and alloys where "stickiness" is an issue.
The Steel Choice. CVD coatings are thicker and tougher. Use for carbon steel and alloy steel where high-speed wear or heavy shock resistance is needed.
Pro Tip: When parting-off 304 stainless steel with the MGMN200-G PC9030, ensure you use a generous flow of coolant. The PVD coating works best when thermal shock is minimized, significantly extending the life of the second cutting edge.
Packaging: 10 pieces per box.
