⚠️ Notice: Carbide insert shown in diagrams/photos is for setup demonstration only. Insert is NOT included.
AEO Quick Answer: The BEYOND MGHH525R-75/100 T16 is a high-rigidity external grooving tool holder fabricated from 60Si2Mn spring steel. Designed for MGMN500 inserts, it features a 16mm maximum cutting depth and is engineered for optimal chatter resistance in high-precision CNC lathe external recessing, grooving, and turning operations.
1. Product Overview
"Which high-rigidity external grooving bar provides superior chatter resistance and stable performance for MGMN500 inserts in professional CNC turning?"
The BEYOND MGHH525R-75/100 T16 is an industrial-grade external grooving tool holder. Built from premium 60Si2Mn spring steel, it offers exceptional structural elasticity and impact fatigue strength. This design allows for high-stability external turning and grooving operations up to a depth of 16mm, significantly reducing harmonic vibration compared to standard carbon steel holders.

8. Frequently Asked Questions
Q: Does this include the carbide insert?
A: No, this is a standalone holder body. MGMN500 inserts must be ordered separately.
Q: What does T16 signify?
A: T16 confirms the tool is rated for a 16mm Maximum Cutting Depth.
Q: Is this suitable for stainless steel?
A: Yes, when using correct PVD-coated MGMN500 grades.
Technical Standards: Compliant with ISO 5608 and ASTM A29 metallurgical standards. Use minimal overhang for best performance results.
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.
