Korloy MGMN600-M NC3020 6mm Double-Ended High-Speed Steel Grooving Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN600-M NC3020 is the definitive solution for High-Efficiency Heavy-Duty Machining. Featuring a massive 6.0mm Double-Ended blade, this insert is built for the most demanding parting and grooving tasks on large-diameter steel components. The NC3020 CVD grade is engineered for maximum wear resistance, allowing for higher cutting speeds and longer tool life in stable CNC environments where heat management and edge retention are critical.
Maximum Metal Removal Rate: At 6.0mm wide, NC3020 excels in high-speed, continuous cutting. It is the ideal choice for modern, high-power CNC lathes that can maintain consistent surface speeds on large workpieces.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN600-M |
| Insert Width (w) | 6.0 mm |
| Grade | NC3020 (Industrial High-Wear CVD) |

Core Performance Benefits:
- Extreme Heat Resistance: Thick CVD coating provides a robust thermal barrier for 6mm wide chip removal.
- Unmatched Rigidness: The extra-wide body prevents deflection and chatter during deep radial plunging in large bars.
- Extended Tool Life: NC3020’s substrate is optimized to resist abrasive wear, reducing the frequency of tool changes in 24/7 production.
- Optimized Geometry: The -M chipbreaker ensures chips are compressed and cleared efficiently, even from deep, wide grooves.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Carbon Steel (1045/45#) | 130 - 220 m/min | 0.15 - 0.35 mm/rev |
| Alloy Steel (4140/4340) | 100 - 180 m/min | 0.12 - 0.30 mm/rev |
| Mild Steel (A3) | 150 - 280 m/min | 0.15 - 0.40 mm/rev |
Compatible Tool Holders:

- External Holders: MGEHR 2525-6 / 3232-6 / 4040-6
Production Tip: NC3020 vs. NC3030 for 6.0mm Width
At 6.0mm, you are removing a lot of material. Your choice should reflect your setup:
The Efficiency King. Best for stable CNC machines and long continuous cuts. It stays sharp longer at high speeds but can chip if the cut is heavily interrupted.
The Tough Armor. Best for interrupted cuts or older machines with vibration. Choose this if your 6mm cuts are "banging" or clicking due to interruptions.
Machinist's Pro Tip: For MGMN600-M NC3020, machine rigidity is paramount. Use the largest tool holder possible (e.g., 3232 or 4040 shank) to take full advantage of the NC3020's high-speed capabilities and ensure a vibration-free finish on large shafts.
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.
