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
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.
