The Original Korloy MGMN200-M PC9030 is a high-performance 2.0mm Double-Ended Grooving Insert specifically engineered for Stainless Steel and General Steel Machining. Featuring the legendary PC9030 PVD grade, this insert is the industry's go-to choice for tackling the challenges of gummy materials like 304 and 316 stainless steel. Its high-toughness substrate and specialized PVD coating prevent built-up edge (BUE) and chipping, ensuring precision and reliability in narrow-groove applications.
Stainless Steel Specialist: PC9030 is optimized to resist the high heat and work-hardening characteristic of stainless alloys. At 2.0mm width, it offers a perfect balance between material efficiency and tool strength for parting off tubes and solid bars.

Core Performance Benefits:
- Anti-Sticking Technology: Specialized PVD layer reduces friction and prevents material welding on the cutting edge.
- Exceptional Toughness: High-quality sub-micron substrate resists fracturing during interrupted or heavy-load cuts.
- Versatile Precision: The -M chipbreaker geometry ensures stable chip control across a wide range of feed rates.
- High Thermal Stability: Maintains hardness at elevated temperatures, ideal for tough-to-cut stainless alloys.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (304/316) | 80 - 150 m/min | 0.05 - 0.12 mm/rev |
| Mild Steel / Low Carbon Steel | 100 - 180 m/min | 0.05 - 0.15 mm/rev |
| Heat Resistant Alloys | 30 - 60 m/min | 0.04 - 0.10 mm/rev |
Compatible Tool Holders:
For high-precision 2.0mm grooving, we recommend these rigid MGEHR/L holders:
- External Holders: MGEHR 1010-2 / 1212-2 / 1616-2 / 2020-2 / 2525-2
The Grade Choice: PC9030 vs. PC5300
Korloy offers different PVD coatings for varied challenges. Here is how they compare for 2.0mm grooving:
The Stainless Specialist. Optimized for the sticky nature of M-group materials. It provides much better tool life in stainless steel compared to general-purpose grades.
The Universal Tough Grade. Excellent for carbon steel and interrupted cuts in general steel, but may experience faster crater wear in high-nickel stainless steels.
Machinist's Pro Tip: For MGMN200-M PC9030 on stainless steel, use high-pressure coolant if possible to wash away long stringy chips and reduce heat at the narrow 2.0mm tip. If dry cutting, reduce cutting speed by 20% to avoid premature edge deformation.
Packaging: 10 pieces per box.
