Iscar 5502397 Vcmt 331-14 IC20 Carbide Turning Insert

Product Description

The ISCAR 5502397 is a solid carbide, uncoated turning insert in the VCMT style, designed for precision turning and boring operations on CNC lathes and turning centers. It carries the ISO designation VCMT 331-14 and belongs to the Isoturn series. The insert features a 35-degree diamond shape with a positive rake geometry, a 7-degree relief angle, and a 1/64 inch (0.0160 inch) corner radius. With an inscribed circle of 3/8 inch and an insert length of 0.654 inch (16.61 mm), it is suited for light-to-medium material removal across a broad range of workpiece materials. Installation is secured via screw-clamp holding method.

This insert is rated for universal workpiece material compatibility, covering ISO material groups H, K, M, N, and S. It is used in general-purpose finishing and semi-finishing turning applications, as well as boring operations where the multi-use designation applies. The Isoturn series is a standard ISCAR platform commonly found in production turning environments handling ferrous metals, non-ferrous alloys, heat-resistant superalloys, and hardened materials. Maximum depth of cut is 0.197 inch (5.00 mm).

Installation Notes

This insert is installed by a machinist or CNC tooling technician into a compatible VCMT-style screw-clamp toolholder. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to seat the insert properly. Inspect the insert pocket for chips or debris before seating a new insert to ensure accurate positioning.
