BEYOND SVVCN2020K16 External Turning Tool Holder
72.5° Lead Angle Neutral Shank for V-Shape Profiling Inserts
Product Overview
"Which neutral tool holder is most stable for 35-degree diamond insert profiling on medium-sized CNC lathes?"
The BEYOND SVVCN2020K16 is an industrial-grade external tool holder designed for the highly versatile VCMT 1604 and VCGT 1604 inserts. Featuring a 72.5° lead angle and a neutral (center) orientation, it allows for balanced cutting forces during intricate profiling and contouring. The 20x20mm shank is forged from high-tensile alloy steel, providing the extreme rigidity required to maintain tight tolerances and eliminate chatter when using the sharp, slender geometry of V-shaped inserts.
Key Features
72.5° Dynamic Lead Angle
Engineered for clearance during deep profiling, allowing the 35° diamond insert to access tight contours without tool-body interference.
40Cr Hardened Alloy
Vacuum-quenched to HRC 42-45. This ensures the insert pocket maintains its precision geometry even under high thermal and mechanical stress.
S-Type Screw Clamping
Specifically designed for V-shaped inserts, providing maximum clamping force to prevent insert "lifting" during back-turning or profiling.

Global Machinist Reviews
"Profiling king"
Thomas R., USA
Great clearance for deep profiles. The 20mm shank is solid and the VCMT16 fits perfectly. Highly recommend.
"Exzellentes Preis-Leistungs-Verhältnis"
Markus W., Germany
Very fast shipping to Munich. The quality of the 40Cr steel is comparable to much more expensive brands.
"Buon Prodotto"
Giovanni B., Italy
Used for stainless profiling. Very stable neutral holder. Seat is very accurate.
Expert Tooling FAQ
Q: Why choose the SVVCN over a right-hand (SVJCR) holder?
A: The neutral SVVCN is better for balanced profiling and when you need to switch between left and right cutting directions on certain CNC paths without changing tools.
Q: Is this holder suitable for VCGT polished inserts for aluminum?
A: Absolutely. The pocket precision of the SVVCN2020K16 is designed to hold both standard VCMT and high-precision VCGT aluminum inserts securely.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
