Description Product Overview The Iscar SVJNL 2020K-12F is a heavy-duty, high-precision External Turning and Profiling Toolholder, engineered for complex CNC lathe work where standard 80-degree tools simply cannot reach. Left-Hand Orientation: This is the Left-Hand (L) cutting counterpart to the SVJNR. It is designed to feed away from the chuck on a standard setup, or it can be used inverted (upside down) on a sub-spindle depending on your machine’s configuration. Aggressive Profiling: This “J-style” holder provides a 93-degree approach angle and is designed to carry aggressive 35-degree diamond inserts (VNMG / VNGG size 12). This makes it the absolute perfect tool for deep undercutting, intricate profiling, and precision finishing operations where clearance is exceptionally tight. Maximum Rigidity: Unlike standard screw-on holders that can allow the insert to micro-shift under heavy loads, this Iscar holder features a specialized screw-lock with a wedge clamping mechanism. This pulls the insert tightly into the pocket, maximizing rigidity and eliminating chatter during finishing passes. Standard 20mm Shank: It features a highly versatile 20mm x 20mm square shank, making it an instant drop-in fit for most medium-sized CNC turning centers and quick-change toolposts. Condition Used (Good Condition / In Original Box). This toolholder is in used condition, showing the standard visual patina and coolant staining of a veteran shop-floor tool, but it remains fully functional and ready to cut. Mechanical Integrity: The insert pocket is clean and undeformed, free of any catastrophic crash damage. The threads and wedge clamping mechanism work smoothly, ensuring your inserts will seat perfectly every time. Included: It comes safely packed in its original Iscar factory plastic tube/box for safe and organized storage in your tooling cabinet. (Note: Inserts are not included). Brand Information Iscar (Israel) is a global titan in carbide cutting tools and metal removal technology. Their turning toolholders are the industry standard for high-production CNC environments, prized for their superior steel metallurgy, precise pocket machining, and unyielding clamping mechanisms that drastically extend insert life.
