Kennametal 4042936 Indexable Drill Insert Sppxfp KCU40

Product Description

The KENNAMETAL 4042936 is a carbide indexable drill insert in SPPX style with an FP chipbreaker geometry and KCU40 grade, designed for use in indexable insert drills on CNC machining centers and production drilling applications. The insert carries a PVD-applied TiN and TiAlN dual-layer coating that improves wear resistance and tool life in a range of ferrous and non-ferrous workpiece materials. With an inscribed circle of 0.369 inches and a thickness of 0.1563 inches, this insert seats precisely in compatible drill bodies to maintain positional accuracy at the cutting edge. Installation and replacement are performed by machining technicians and toolroom personnel during scheduled insert indexing cycles.

This insert is suited for drilling operations in production and job-shop environments where consistent hole quality and predictable tool life are required. The FP chipbreaker geometry promotes reliable chip formation and evacuation in through-hole and blind-hole drilling. The KCU40 carbide grade with PVD coating is appropriate for use at moderate to high cutting speeds in materials including carbon steel, alloy steel, and cast iron. It is sold individually but carries a minimum order quantity of 5 units per order.

Installation Notes

Indexable drill inserts are installed and indexed by qualified machining technicians or toolroom personnel. Power down and lock out the machine spindle before removing or seating any insert. Use the correct torx or hex key specified by the drill body manufacturer to achieve proper clamping torque — do not over-torque the clamping screw, as this can fracture the insert or damage the pocket seat. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert.
