Kennametal 5660035 Milling Insert SP6519 Solid Carbide Apkt

Product Description

The KENNAMETAL 5660035 is a solid carbide milling insert in the APKT series, manufactured to grade SP6519 with a TiAlN coating applied via PVD process. The parallelogram insert geometry carries an 11-degree relief angle and an insert size code of 1604, placing it in the APKT 16 size family. At 0.187 inches thick and 0.31 inches wide, with an inscribed circle of 0.25 inches, this insert is engineered for consistent cutting performance in indexable milling applications. The TiAlN PVD coating provides thermal resistance and wear protection suited to a broad range of workpiece materials. Licensed machinists and tooling specialists install this insert in compatible indexable milling toolholders.

This insert is used in indexable end mills, face mills, and shoulder milling cutters that accept APKT-style inserts. It is suited for machining operations in metalworking environments, including production shops and job shops handling ferrous and non-ferrous materials. The 45-degree chip breaker geometry promotes controlled chip formation during milling passes. This insert is sold individually but carries a minimum order quantity of 10 units per purchase.

Installation Notes

Installation is performed by machinists or tooling technicians using the appropriate torx or hex key as specified by the toolholder manufacturer. Ensure the machine spindle is fully stopped and the toolholder is secured in a vise or fixture before seating or removing inserts. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert. Follow the toolholder manufacturer's clamping torque guidelines and do not overtighten the retention screw.
