Iscar 5696840 Lnet 125708-TN IC910 Milling Insert

Product Description

The ISCAR 5696840 is an LNET 125708-TN IC910 grade tangential milling insert designed for slotting and milling operations in steel and cast iron. The insert is manufactured from solid carbide and carries an AlTiN coating applied via PVD process, which supports performance in abrasive and interrupted-cut conditions. The butterfly-shaped insert geometry features a negative rake angle, a T-Land cutting edge style, and a 0-degree relief angle. With four cutting edges per insert and a corner radius of 0.0315 inches, it delivers consistent stock removal per edge. The insert thickness is 0.3750 inches and the inscribed circle diameter measures 0.2264 inches. Licensed trades and tooling specialists install this insert as part of carbide indexable tooling programs.

This insert belongs to the ISCAR TANGSLOT series and is compatible with FDN and SDN cutter bodies. It is engineered for primary use in steel (ISO material code P) and cast iron (ISO material code K) applications. Typical install scenarios include slotting operations on CNC machining centers and manual mills where tangential insert orientation is required to maximize cutting edge strength and chip control. The insert is neutral-handed, making it suitable for a range of tool body configurations without left- or right-hand orientation constraints. Minimum order quantity is 10 units, with individual package quantity of one insert per package.

Compatibility

Designed for use with ISCAR TANGSLOT series cutter bodies, specifically FDN and SDN cutter series. Conforms to ANSI standard LNET 125708-TN IC910 and ISO 13399 standard LNET 125708-TN. Screw-held insert mounting method required on compatible cutter bodies.

Installation Notes

Installation is performed by machinists or tooling technicians on indexable milling tool bodies. Power down and de-energize the machine spindle completely before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the cutter body manufacturer to seat the screw-held insert securely. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert to ensure proper seating and runout control.
