Iscar 5696610 Milling Insert Lnet 124004-TN IC928 Carbide

Product Description

The ISCAR 5696610 is a solid carbide milling insert carrying the manufacturer designation LNET 124004-TN in grade IC928. It belongs to the TANGSLOT series and is designed for slotting and milling operations requiring high edge stability and resistance to heat buildup. The insert features a TiAlN coating applied via PVD process, a butterfly (LNET) shape, and a negative rake geometry with a T-Land cutting edge style. With four usable cutting edges per insert, a 0.5000-inch cutting edge effective length, and a maximum depth of cut of 0.5000 inches, it suits demanding metal removal applications. Licensed tradespeople and machinists working in production or maintenance environments will recognize this as a direct-fit insert for compatible ISCAR cutter bodies.

This insert is engineered for cutting steel, stainless steel, superalloys, and titanium — workpiece material codes P, M, and S under ISO classification. It is held in the cutter body by a screw-clamp method and carries a neutral hand designation, making it suitable for a range of slotting configurations. The IC928 grade is matched to interrupted cuts and difficult-to-machine alloys where thermal and mechanical shock resistance are priorities. Cutter series compatibility includes the FDN and SDN bodies within the ISCAR TANGSLOT platform.

Key Features

• LNET butterfly insert shape with 90-degree included angle and negative rake for stable edge engagement
• IC928 grade with TiAlN PVD coating — suited for steel, stainless steel, superalloys, and titanium
• Four cutting edges per insert, single-sided configuration
• T-Land cutting edge style improves edge strength on hard and abrasive workpiece materials
• Screw-clamp insert holding method for secure, repeatable seating in the cutter pocket
• Compliant with ANSI and ISO 13399 standards; ANSI code LNET 124004-TN IC928

Compatibility

Compatible with ISCAR TANGSLOT cutter bodies in the FDN and SDN series. Insert size code 124004 with an inscribed circle of 0.1575 inches and a length of 0.5000 inches. Verify pocket geometry and screw specification against the applicable cutter body documentation before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians following the cutter body manufacturer torque specifications for the insert clamping screw. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Inspect the pocket seat and clamping screw for wear or debris before seating the new insert. Do not force the insert into the pocket — proper seating should require only the specified clamping torque with no lateral pressure.
