BEYOND SVUCR2020K11 External Turning Tool Holder
Precision 20mm Shank for VC..1103 Series Inserts
1. Product Overview
The BEYOND SVUCR2020K11 is a high-performance external turning tool holder specifically designed for VC..1103 (VCMT 22x) carbide inserts. Featuring a 93° approach angle, it provides excellent clearance for complex profiling geometries. The screw-down clamping system offers an unobstructed chip flow path, essential for maintaining superior surface finishes in precision machining.
2. Key Features
- Industrial Grade Alloy Steel: Optimized heat-treatment for maximum vibration dampening and tool life[cite: 1].
- Precision Profiling: 93° lead angle ensures clearance for intricate contours and finishing passes[cite: 1].
- Screw-Clamping Stability: Minimalist design reduces interference while securing the insert firmly[cite: 1].

4. Applications & 5. Compatibility
The SVUCR2020K11 is optimized for external profiling and finishing on manual and CNC lathes[cite: 1]. It is fully compatible with ISO-standard VC..1103 inserts from BEYOND, Sandvik, Kennametal, and Kyocera[cite: 1].
7. Why Choose BEYOND?
"The 20mm shank fits my HAAS perfectly. Rigid design reduces chatter significantly on profiling runs."[cite: 1]
"Hervorragende Qualität. The surface finish on my stainless parts is glass-like. Best value for B2B procurement."[cite: 1]
"Ottimo prodotto. Very reliable tool holder for my small workshop. Shipping was fast too."[cite: 1]
8. Expert FAQ
Q: Is this holder suitable for heavy roughing?
A: No, the 35° rhombus geometry (VC.. inserts) is specifically engineered for profiling and light finishing. For roughing, we recommend our CNMG or WNMG holders[cite: 1].
Q: What is the benefit of the 93° approach angle?
A: It allows for clearance on longitudinal turning and complex contours without the tool body interfering with the workpiece[cite: 1].
Technical Tips & Maintenance
Grade Insight: Pair with PVD-coated inserts for stainless steel and CVD-coated inserts for high-speed steel turning[cite: 1].
Equivalent Models: Sandvik SVUCR 2020K 11 | Iscar SVUCR 2020K-11 | Kennametal SVUCR 2020K11[cite: 1].
Troubleshooting: If experiencing tool deflection, ensure the overhang length is kept to a minimum. Always check center height alignment[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.
