Iscar 5605999 Milling Insert Lnet 081804-TN-N IC928 Carbide

Product Description

The ISCAR 5605999 is a solid carbide milling insert carrying ANSI/ISO designation LNET 081804-TN-N in grade IC928. It features a butterfly (LNET) insert shape with a 90-degree included angle, four cutting edges, and a TN chip breaker geometry. The insert is coated with TiAlN via a PVD process, producing a hard, wear-resistant surface suited to demanding cutting conditions. With a negative rake angle and T-Land cutting edge style, it is designed for stable, controlled material removal. This insert is held in place by a screw-type clamping method and is used in face and slot milling operations on CNC machining centers and milling machines.

This insert is engineered for cutting steel, stainless steel, superalloys, and titanium — material groups P, M, and S under ISO classification. The TiAlN PVD coating provides the thermal resistance needed when machining heat-resistant alloys and austenitic stainless grades. It is compatible with ISCAR TANGSLOT series cutter bodies, specifically the ETS-LN08 and FDN-LN08 cutter series. Typical users include CNC machinists and tooling specialists in aerospace, oil and gas, and general metalworking shops running high-value workpiece materials.

Key Features

• IC928 solid carbide grade with TiAlN PVD coating for wear and heat resistance in steel and superalloy applications
• Four cutting edges per insert — neutral hand orientation for flexible setup
• Butterfly (LNET) insert shape with 90-degree included angle and T-Land cutting edge style
• TN chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium
• Negative rake angle with zero relief angle for maximum edge strength under interrupted and heavy cuts
• Screw-type insert holding for secure, repeatable seating in compatible TANGSLOT cutter bodies

Compatibility

Designed for use with ISCAR TANGSLOT series cutter bodies ETS-LN08 and FDN-LN08. Insert size code 081804; ANSI code LNET 081804-TN-N IC928; ISO code LNET 081804-TN-N. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key specified for the cutter body screw to avoid overtorquing the insert clamp screw, which can crack the carbide. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert.
