BEYOND SVUCL2020K11 External Turning Tool Holder
Precision 20mm Shank for VC..1103 Series Inserts
1. Product Overview
The BEYOND SVUCL2020K11 is a professional-grade external turning tool holder designed for VC..1103 (VCMT 22x) carbide inserts. With a 93° approach angle, it provides exceptional clearance for intricate profiling and finishing operations where surface finish is critical. The screw-down clamping system ensures a clear path for chip flow, making it the industrial standard for efficient CNC machining.
2. Key Features
- Industrial Grade Alloy Steel: Heat-treated for maximum toughness and vibration dampening during high-speed finishing[cite: 1].
- Unobstructed Chip Flow: Screw-clamping mechanism minimizes interference, essential for maintaining surface integrity[cite: 1].
- 93° Approach Angle: Engineered for precision profiling where standard holders may interfere with the workpiece[cite: 1].

7. Why Choose BEYOND?
"Perfect fit for my HAAS turret. Rigid and gives a great surface finish."[cite: 1]
"Top Qualität. Fast shipping and the tolerances are spot on."[cite: 1]
"Consistent and reliable for long production runs on 304 stainless."[cite: 1]
8. Expert FAQ
Q: Is this holder suitable for roughing?
A: The 35° rhombus insert is optimized for profiling and finishing. For heavy roughing, we recommend our CNMG or WNMG holders[cite: 1].
Q: What is the difference between SVUCL and SVUCR?
A: SVUCL is Left-Handed; SVUCR is Right-Handed. Choose based on your machine turret setup[cite: 1].
Technical Tips & Maintenance
Grade Insight: Pair with PVD-coated inserts for stainless steel and CVD-coated for high-speed steel turning[cite: 1].
Equivalent Models: Sandvik SVUCL 2020K 11 | Iscar SVUCL 2020K-11 | Kennametal SVUCL 2020K11[cite: 1].
Troubleshooting: If experiencing vibration, check the tool center height. Ensure the tool is set precisely at the workpiece center line[cite: 1].
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.
