BEYOND SVVCN1616H11 External Turning Tool Holder
16mm Neutral Shank | 72.5° Lead Angle for VCMT 1103 Profiling
Product Overview
"Which neutral tool holder is best for 35-degree diamond profiling on a 16mm CNC lathe turret?"
The BEYOND SVVCN1616H11 is a specialized external tool holder engineered for high-precision profiling using VCMT 1103 or VCGT 1103 inserts. Its 72.5° approach angle and neutral shank design provide the necessary clearance for intricate contours and multi-directional turning. Forged from high-grade 40Cr alloy steel, this holder eliminates chatter during finishing passes, allowing for mirror-like surface finishes even on tough alloys. The S-type screw clamping system ensures the insert remains perfectly centered under high centrifugal forces common in modern CNC cycles.
Key Features
Precision 72.5° Lead Angle
Optimized for 35° V-inserts, allowing for deep profiling and relief turning where standard 90° tools would interfere.
Heat-Treated 40Cr Steel
Hardened to HRC 42-45 through vacuum quenching, offering superior durability and resistance to thermal deformation.
Streamlined Chip Flow
The neutral shank and low-profile screw clamp design prevent chip bird-nesting, critical for lights-out CNC production.

Global Machinist Feedback
"Profiling king"
Thomas R., USA
The SVVCN neutral holder is my go-to for complex profiles. Clearance is perfect and the 16mm shank fits my turret like a glove.
"Top Qualität"
Dieter S., Germany
Beyond tools never disappoint. The heat treatment on the steel is noticeable—no vibration even at high speeds.
"Great Neutral Tool"
Yoshi T., Japan
Hard to find good neutral holders in 16mm. This one holds the VCMT 1103 very securely. Fast shipping.
Expert Tooling FAQ
Q: Why use a neutral (N) holder instead of a right-hand (R) holder?
A: Neutral holders like the SVVCN are ideal for symmetrical profiling where you need clearance on both sides or when performing dual-directional turning cycles.
Q: Is this holder suitable for VCGT polished inserts for aluminum?
A: Yes. The precision pocket design is fully compatible with both VCMT (Steel/Stainless) and VCGT (Aluminum) 1103 inserts.
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.
