BEYOND SVJCL2020K16 External Turning Tool Holder
Product Overview
"Which left-hand tool holder is best for 93° profiling and medium finishing on medium-sized steel workpieces using V-shape inserts?"
The BEYOND SVJCL2020K16 is an industrial-grade, left-hand (LH) external turning holder designed for 35° rhombic VCMT 1604 or VCGT 1604 inserts. With a 20x20mm shank, it strikes the perfect balance between rigidity and accessibility for compact to mid-sized CNC lathes. Its 93° approach angle ensures excellent clearance for profiling and contouring operations, while the high-precision seat ensures maximum insert stability.
Key Features
- 93° Precision Geometry: Specifically engineered for back-turning and profiling without rubbing.
- Forged Alloy Steel: Body hardness reaches HRC 42-45, effectively dampening chatter during high-speed cuts.
- S-Type Clamping: Screw-down mechanism provides a low-profile design and secure insert locking.
- Extreme Wear Resistance: Finished with a specialized black oxide coating to prevent corrosion and chip welding.

Expert Technical FAQ
A: No, this is an external turning holder. For internal boring, please look for our 'E-SVUCL' series boring bars.
A: SVJCL is Left-Handed (cutting toward the headstock in specific setups), and SVJCR is Right-Handed. Always check your machine turret's rotation.
A: The SVJCL2020K16 is an S-type holder where the insert sits directly on the precision-milled pocket for maximum clearance. No shim required.

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.
