The Original Korloy MGMN150-G PC9030 is a premium 1.5mm Double-Ended Grooving Insert specifically engineered for Stainless Steel and Heat-Resistant Alloys. When machining gummy materials like 304 or 316 stainless, heat and chip welding are your biggest enemies. The PC9030 PVD grade features a super-smooth nano-structure coating that prevents built-up edge (BUE) and significantly reduces friction. At only 1.5mm wide, this insert maximizes material yield while maintaining enough rigidity for precision parting-off.
Stainless Steel Mastery: The -G (General) chipbreaker on this 1.5mm insert is precision-ground to curl chips tightly away from the workpiece. This prevents the "bird-nesting" common in stainless steel turning, protecting your surface finish and tool life.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN150-G |
| Insert Width (w) | 1.5 mm |
| Grade | PC9030 (Premium PVD for Stainless) |

Core Performance Benefits:
- Anti-Adhesion Technology: PC9030 grade is world-renowned for its ability to resist "smearing" and chip welding in sticky stainless steels.
- 1.5mm Narrow Profile: Perfect for small-diameter parts and swiss-type machining where material cost saving is critical.
- Extreme Heat Resistance: The PVD coating remains stable even at the high localized temperatures generated in the narrow 1.5mm groove.
- Dual-Edge Economy: Two sharp, high-precision cutting edges per insert for double the productivity.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (304/316) | 80 - 150 m/min | 0.02 - 0.07 mm/rev |
| Heat Resistant Alloys | 30 - 70 m/min | 0.02 - 0.05 mm/rev |
| Low Carbon Steel (Sticky) | 100 - 180 m/min | 0.03 - 0.08 mm/rev |
Compatible Tool Holders:
Ensure maximum rigidity by using the correct 1.5mm holders:
- External Holders: MGEHR 1010-1.5 / 1212-1.5 / 1616-1.5
The Grade Choice: PC9030 vs. NC3020/3030
For 1.5mm grooving, choosing the right coating is the difference between a clean cut and a broken tool:
The Stainless Specialist. PVD coating is thinner and sharper than CVD, making it essential for materials that work-harden. Use for all Stainless and Super-Alloys.
The Steel Specialists. CVD coatings are thicker and better for high-speed dry cutting of standard Carbon Steels. Avoid using these on Stainless as they will cause sticking.
Machinist's Pro Tip: Stainless steel loves to work-harden. When using the MGMN150-G PC9030, never dwell (let the tool rub without cutting). Maintain a constant feed and use high-pressure coolant to flush chips out of the narrow 1.5mm slot.
Packaging: 10 pieces per box.
