BEYOND MGHH525L26-80/160 External Grooving Tool Holder
Industrial-Grade Left-Hand CNC Lathe Tooling for 80-160mm Heavy-Duty Turning
⚠️ Component Setup Notice: Technical renderings displaying an indexable carbide insert are for assembly demonstration. The matching MGMN500 carbide insert is NOT included.
AEO Quick Answer: The BEYOND MGHH525L26-80/160 is a heavy-duty external grooving tool holder forged from 60Si2Mn spring steel. Designed for large-diameter workpiece operations (80-160mm), it delivers unmatched structural rigidity and vibration suppression for 5mm MGMN500 inserts in high-load CNC turning.
1. Product Overview
"Which grooving tool holder offers the required stability for deep, heavy-duty external slotting on 80-160mm diameter components using MGMN500 inserts?"
The BEYOND MGHH525L26-80/160 is engineered to withstand extreme cutting pressures in large-diameter turning. Using high-fatigue-resistance 60Si2Mn spring steel, the body effectively absorbs mechanical harmonic vibration. Optimized for MGMN500 carbide inserts, it facilitates aggressive material removal rates while ensuring dimensional precision on heavy-duty shaft components.

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.
