Kennametal 4042892 Indexable Drill Insert Sppxhp KCPK10

Product Description

The KENNAMETAL 4042892 is a solid carbide indexable drill insert in the SPPX style with an HP chipbreaker geometry and KCPK10 grade designation. It carries a CVD-applied TiCN and Al2O3 multilayer coating designed to extend tool life in demanding drilling applications. With a 0.369-inch inscribed circle, a 0.1563-inch thickness, and a 0.039-inch corner radius, this insert is sized for precision indexable drill bodies that accept the SPPX insert form. Machinists and tool-crib technicians working in production or job-shop environments install this insert as a replaceable cutting element in indexable drill tooling systems.

This insert is suited for indexable drilling operations on machining centers, CNC lathes with live tooling, and dedicated drilling machines. The HP chipbreaker geometry promotes effective chip evacuation in through-hole and blind-hole drilling across a range of workpiece materials. The KCPK10 carbide grade with CVD TiCN and Al2O3 coating targets applications where heat resistance and wear resistance are priorities, such as drilling cast iron, steel, and similar ferrous materials in medium-to-high production environments.

Key Features

• SPPX insert style with HP chipbreaker geometry for controlled chip formation
• KCPK10 solid carbide grade with CVD-applied TiCN and Al2O3 multilayer coating
• 0.369-inch inscribed circle and insert size 09T310 for precise tool body fit
• 0.039-inch corner radius reduces edge chipping at drill entry and exit
• 0.1417-inch hole diameter for secure mechanical clamping in compatible drill bodies
• 0.1563-inch insert thickness provides rigidity under axial drilling loads

Compatibility

Designed as a replaceable indexable insert for drill bodies that accept the SPPX insert style in insert size 09T310 with a 0.1417-inch mounting hole diameter.

Installation Notes

Installation is performed by machinists or tool-crib personnel. Power down and lock out the machine spindle before seating or removing any indexable insert. Use the correct torque wrench and manufacturer-specified clamp screw for the drill body to avoid over-torquing the mounting hole. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert, as contamination in the pocket can cause premature insert failure or runout.
