Korloy MGMN600-M NC3030 6mm Double-Ended Heavy-Duty 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 NC3030 is the largest standard 6.0mm Double-Ended Grooving Insert in the range, engineered for Industrial-Scale Steel Machining. When parting off massive solid bars or machining deep, wide grooves in high-tensile materials, 6.0mm of carbide provides the ultimate structural integrity. The NC3030 CVD grade is specifically optimized for shock resistance, allowing the tool to power through interrupted cuts and rough surfaces on large-scale forgings and castings.
Maximum Stability for Large Parts: The 6.0mm width is designed to minimize vibration (chatter) during deep radial plunges. This is the heavy-duty choice for workshops servicing the oil & gas, mining, and heavy energy industries.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN600-M |
| Insert Width (w) | 6.0 mm |
| Grade | NC3030 (Ultra-Tough CVD Coated) |
| Primary Use | Large Steel Bars / Forgings / Heavy Interruption |
Core Performance Benefits:
- Anti-Vibration Design: The massive 6.0mm cross-section absorbs harmonics, ensuring a stable cut in large-diameter workpieces.
- Extreme Impact Resistance: NC3030's specialized substrate is built to survive repetitive shocks from hex-bars or large cross-holes.
- Advanced Thermal Shield: Multi-layer CVD coating protects the cutting edge from the intense heat generated during 6mm wide metal removal.
- Heavy-Duty Chip Breaking: The -M geometry is specifically tuned for higher feed rates, ensuring chips are curled and broken even in deep grooves.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Heavy Carbon Steel (1045/45#) | 80 - 170 m/min | 0.15 - 0.35 mm/rev |
| Alloy Steel (4140/4340) | 60 - 140 m/min | 0.12 - 0.30 mm/rev |
| Large Steel Castings | 50 - 110 m/min | 0.15 - 0.25 mm/rev |
Compatible Tool Holders:
Requires heavy-duty 6.0mm MGEHR/L external holders for maximum clamping force:
- External Holders: MGEHR 2525-6 / 3232-6 / 4040-6
The Heavy Industry Choice: NC3030 vs. PC5300
At a 6.0mm width, the demands on the tool grade are extreme. Choose based on your workpiece condition:
The Tank. Best for large-scale steel parting with vibrations, interruptions, or manual feed. It is the toughest grade for heavy removal.
The All-Rounder. Use if you are alternating between Large Steel and Stainless Steel parts. Offers better versatility but lower shock resistance than NC3030.
Machinist's Pro Tip: For the MGMN600-M NC3030, ensure your machine has enough horsepower. A 6mm wide cut creates significant torque. If you hear a "squealing" noise, increase the feed rate ($f$) to engage the chipbreaker properly and ensure the tool is dead-center.
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.
