Iscar 5607261 Lnet 125516-TN IC328 Milling Insert

Product Description

The ISCAR 5607261 is a solid carbide milling insert with ANSI designation LNET 125516-TN IC328, designed for slotting and milling operations in demanding material applications. The insert features a butterfly (LNET) shape with a 90-degree included angle, negative rake geometry, and a T-Land cutting edge style. It is coated with TiCN via PVD process using the IC328 grade, which is engineered for cutting steel, stainless steel, superalloys, and titanium. With four cutting edges and a neutral hand orientation, this insert is suited for high-productivity setups in CNC milling environments. It is installed by machining professionals and tooling technicians on compatible ISCAR cutter bodies.

This insert is part of the ISCAR TANGSLOT series and is compatible with FDN and SDN cutter series bodies. It is intended for single-sided use in slotting applications with a maximum depth of cut of 0.5000 inches. Primary workpiece materials include steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. The TN chip breaker geometry helps manage chip flow in these materials. This insert is appropriate for both roughing and finishing passes depending on feed and speed parameters set by the operator.
