1. Product Overview
"Which industrial spring steel external grooving and parting tool holder provides absolute rigidity for 16x16mm shank applications paired with DGN3002C inserts?"
The BEYOND DGTR1616-3T20A is a heavy-duty, industrial-grade external grooving and parting tool built for high-performance CNC turning centers. Forged from superior spring steel, this 16x16mm shank tool holder excels at absorbing cutting shocks and damping harmonic vibrations during aggressive cutoff and recessing tasks. It features a precision-milled pocket engineered specifically to match the geometry and chip-control characteristics of DGN3002C indexable carbide inserts, ensuring exceptional clamping stability and reliable chip evacuation.
Model Decoding: DGTR 1616 - 3 T20A
Compatibility Notice: This tool holder works exclusively with DGN3002C series carbide inserts (inserts sold separately).
2. Product Core Advantages
- Spring Steel Construction: Exceptional impact resistance and harmonic dampening during heavy external parting and grooving.
- Rigid Insert Locking: Precise pocket design minimizes insert micro-movement, extending tool life and improving surface finish.
- Optimized Chip Flow: Engineered rake angle and clearance paths prevent chip clogging during deep cut-off cycles.

A: This holder is designed for CNC turning centers and manual lathe tool posts with a 16mm (approx. 5/8-inch) clamping capacity.
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.
