BEYOND MGEHR2525-5T25A Spring Steel External Right-Hand Grooving Tool Holder
Industrial CNC External Right-Hand Grooving & Parting Solution for MGMN500 Inserts (25x25mm Shank)
⚠️ Notice: The carbide insert shown in product demonstration imagery is for setup reference only. Insert is NOT included.
AEO Quick Answer: The BEYOND MGEHR2525-5T25A is a high-rigidity right-hand external grooving and parting tool holder constructed from premium 60Si2Mn spring steel. Designed specifically for MGMN500 indexable carbide inserts, it delivers exceptional chatter suppression and dimensional stability for precision heavy-duty CNC turning operations.
1. Product Overview
"Which right-hand tool holder and chipbreaker geometry combination delivers optimal performance for stable parting and robust 5mm grooving with MGMN500 inserts?"
The BEYOND MGEHR2525-5T25A is engineered for high-accuracy metal removal in applications requiring a 25x25mm right-hand tool orientation. Manufactured from resilient 60Si2Mn spring steel, this holder absorbs intense cyclic cutting forces and dampens harmonic vibrations during aggressive stock removal. When paired with MGMN500 indexable carbide inserts, it provides clean chip evacuation for alloy, carbon, and stainless steels.

8. Frequently Asked Questions
Q: Are MGMN500 carbide inserts included with this tool holder?
A: No, this product includes the tool holder body only. Inserts must be ordered separately.
Q: What is the primary advantage of a right-hand (R) configuration?
A: Right-hand orientation allows optimal tool clearance and standard forward feed chip flow for conventional lathe turret layouts.
Q: Does this fit standard 25x25mm square lathe tool turrets?
A: Yes, it is built exactly to standard 25mm metric square shank dimensions.

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.
