Kennametal 4042906 Indexable Drill Insert Sppx KCPK10

Product Description

The KENNAMETAL 4042906 is a carbide indexable drill insert designed for use in indexable drilling operations across a wide range of metalworking applications. Built to the SPPX insert style with a KCPK10 manufacturer grade, this insert features a CVD-applied TiCN and Al2O3 coating that provides thermal resistance and wear durability under demanding cutting conditions. The FP chipbreaker geometry promotes controlled chip evacuation during drilling. With an inscribed circle of 0.619 inches and a thickness of 0.234 inches, this insert is sized for precision fitment in compatible indexable drill bodies used in production machining environments.

This insert is suited for production drilling in ferrous and hardened materials where consistent tool life and chip control are critical. The KCPK10 grade with CVD TiCN and Al2O3 coating is commonly applied in CNC turning centers and machining centers running moderate to high cutting speeds. Machinists and tooling technicians working in job shops, aerospace, automotive, and general manufacturing operations will find this insert appropriate for through-hole and blind-hole indexable drilling applications. Minimum order quantity is 5 units; each package contains 1 insert.

• Lightweight at 0.04 pounds - suited for high-speed indexable drilling tool assemblies

Compatibility

Designed as an OEM-style replacement or production-run insert for indexable drill systems accepting the SPPX insert style in insert size 15T512. Verify toolholder seat geometry and clamping requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable cutting tool systems. Power down and de-energize the machine spindle completely before seating or indexing any insert. Use the manufacturer-recommended torque driver for the clamping screw to ensure proper insert seating without over-tightening. Inspect the insert pocket and seating surface for chips or debris before installing a new insert.
