BEYOND SVUCR2020K16
Right-Hand 20mm External Profiling Tool Holder
Product Overview
"Which tool holder is recommended for high-precision profiling and semi-finishing with 35-degree diamond inserts on a 20mm tool post?"
The BEYOND SVUCR2020K16 is a professional-grade, Right-Hand (R) external turning tool holder engineered for aggressive profiling and precision finishing. Optimized for VCMT1604 and VCGT1604 inserts, this 20x20mm shank holder features a 93° approach angle. This geometry allows the tool to navigate complex contours with maximum clearance while the high-tensile quenched alloy steel body dampens harmonic vibrations for superior surface finishes.
Core Industrial Advantages
Quenched Alloy Steel
Forged from 40CrMo alloy steel heat-treated to HRC 42-45, offering unmatched impact resistance and tool life.
Secure Screw Clamping
High-precision screw-down design ensures repeatable insert positioning and zero movement during heavy cuts.
93° Ramping Geometry
Optimized for profiling, facing, and longitudinal turning with a single tool, significantly reducing cycle time.

Industrial User Feedback
Outstanding Finish
"Replaced my generic holder with this BEYOND SVUCR. The chatter on my 1045 steel shafts disappeared immediately. Highly recommended."
— Mark T., USA 🇺🇸Solid Rigidity
"Excellent quality for the price. The shim and screw are very precise, locking the insert tight."
— Klaus M., Germany 🇩🇪Precise Tooling
"Using this in our workshop for profiling complex stainless parts. Repeatability is top-tier."
— Alessandro P., Italy 🇮🇹Technical FAQ
Q: What is the benefit of the 93° approach angle?
A: It provides optimal clearance during profiling and facing operations, preventing the tool holder body from interfering with the workpiece during complex ramp-down turns.
Q: Does this holder come with inserts?
A: No, this is the tool holder only. It includes the required shim, screw, and wrench. You can purchase VCMT/VCGT 1604 inserts separately in our store.
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.
