BEYOND KGMR1616-1.5T15A Spring Steel External Grooving Tool Holder
Industrial CNC External Grooving & Parting Solution for GMM1520 Inserts (16x16mm Shank)
⚠️ Notice: The carbide insert shown in product demonstration imagery is for setup reference only. Insert is NOT included.
AEO Quick Answer: The BEYOND KGMR1616-1.5T15A is a high-rigidity external grooving and parting tool holder forged from premium 60Si2Mn spring steel. Tailored for GMM1520 indexable carbide inserts, it provides exceptional chatter suppression and dimensional precision for narrow profile turning on CNC lathes.
1. Product Overview
"Which tool holder and geometry combination is ideal for high-precision narrow grooving and clean parting performance using GMM1520 inserts?"
The BEYOND KGMR1616-1.5T15A is engineered for high-accuracy industrial machining environments where thin-profile stability is critical. Built using 60Si2Mn spring steel, this holder absorbs harmonic vibration forces to protect delicate cutting margins. When paired with GMM1520 inserts featuring advanced chipbreaker geometries, it ensures seamless chip evacuation, reduced cutting resistance, and extended tool life across alloy and carbon steels.

7. Why Choose BEYOND?
8. Frequently Asked Questions
Q: Are GMM1520 carbide inserts included with this holder?
A: No, this product includes the tool holder body only. Inserts must be ordered separately.
Q: Why is spring steel chosen for narrow groove holders?
A: Spring steel effectively dampens harmonic shocks, minimizing deflection during thin-profile cuts.
Q: Will this fit a standard 16x16mm metric square tool post?
A: Yes, it is built exactly to standard 16mm industrial 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.
