Global Verified Reviews
⭐⭐⭐⭐⭐ "Holds the 2mm insert very tight. No chatter even on stainless."
- Marcus, Germany⭐⭐⭐⭐⭐ "Standard 16mm shank fits my Haas turret perfectly. Good value."
- Robert, UK⭐⭐⭐⭐ "Shipping was fast to Canada. Steel is tough and screw doesn't strip."
- Jason, Canada⭐⭐⭐⭐⭐ "Best parting tool for the price. I'm buying the left-hand one next."
- Liam, AustraliaFrequently Asked Questions
Q: Can I use 3mm width inserts in this holder?
A: No. The pocket is precision machined for 2.0mm wide (MGMN200) inserts only. Using 3mm inserts will damage the holder.
Q: What is the maximum parting diameter?
A: For the 16mm shank MGEHR, the typical maximum parting diameter is approximately 30-35mm depending on machine clearance.
Q: Does it come with spare screws?
A: One screw is installed. Additional spare screws are available in our "Spare Parts" section.

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.
