BEYOND SVUCL2020K16
Precision 20mm Left-Hand External Turning Tool Holder
Product Overview
"Which tool holder is best for high-stability profiling and external finishing using V-bottom diamond inserts on a 20mm tool post?"
The BEYOND SVUCL2020K16 is an industrial-grade Left-Hand (L) external turning tool holder designed for precision profiling. It is the optimal choice for operators using VCMT1604 or VCGT1604 inserts. Crafted from high-tensile quenched alloy steel, this holder features a 93° approach angle, specifically engineered to provide clearance for complex contours while maintaining the rigidity required for vibration-free finishing in steel, stainless, and heat-resistant alloys.
Core Industrial Advantages
Quenched Alloy Steel Shank
Heat-treated to HRC 42-45, ensuring superior impact resistance and preventing shank deformation under heavy cutting loads.
93° Precision Profiling
The specialized geometry allows for aggressive profiling and facing with a single tool, reducing setup time and tool changes.
Nickel-Coated Finish
Enhanced surface treatment provides excellent corrosion resistance and chip-flow smoothness for cleaner work environments.

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.
