Description
Product Overview
The Iscar SVJNR 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.
- 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 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.
- Right-Hand Orientation: This is a Right-Hand (R) cutting tool, designed to feed toward the chuck.
Condition
Used (Good Condition / In Original Box).
This toolholder is in used condition, showing the standard visual patina and coolant staining of a shop-floor tool, but remains fully functional.
- 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 storage in your tooling cabinet. (Note: Inserts are not included).
