Kennametal 4042888 Indexable Drill Insert Spgxmd KCPK10

Product Description

The KENNAMETAL 4042888 is a solid carbide indexable drill insert designed for use in indexable drilling tool systems. It carries the SPGXMD insert style with KCPK10 grade and features a CVD-applied TiCN and Al2O3 multilayer coating that provides wear resistance and thermal protection during cutting operations. The inscribed circle measures 0.307 inches, the insert thickness is 0.1252 inches, and the corner radius is 0.0313 inches. The MD chipbreaker geometry promotes controlled chip evacuation in a range of workpiece materials. This insert is installed and changed out by machinists and toolroom technicians performing drilling operations on CNC machining centers and similar equipment.

This insert is suited for indexable drill bodies that accept the SPGX insert style and KCPK10 grade. It is appropriate for production drilling in ferrous and non-ferrous materials where controlled chip flow and thermal resistance are required. The CVD TiCN and Al2O3 coating stack makes it a practical choice for steel and cast iron applications at moderate to high cutting speeds. The 0.1120-inch hole diameter accommodates standard insert retention hardware for the applicable drill body platform.

• Inscribed circle of 0.307 inches with insert size designation 070308
• Corner radius of 0.0313 inches for defined cutting edge geometry
• 0.1120-inch hole diameter for standard insert screw retention

Compatibility

Designed for use in indexable drill bodies that accept the SPGX insert style with KCPK10 grade tooling. Consult the applicable drill body documentation to confirm insert seat geometry and retention screw compatibility before installation.

Installation Notes

Insert seating and torquing should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before changing inserts. Use the correct insert retention screw and drive tool specified by the drill body manufacturer to avoid seat damage. Inspect the insert pocket for chips or debris before seating the new insert.
