Kennametal 6388690 Replaceable Drill Tip 0.4134 in KCP15A

Product Description

The KENNAMETAL 6388690 is a replaceable drill tip designed for use with compatible KTFS-series modular drill bodies. It features a 0.4134-inch (10.50 mm) cutting diameter and a 143-degree drill point angle optimized for controlled entry and chip formation in a variety of workpiece materials. The tip is manufactured from solid carbide and carries a KCP15A grade designation, indicating a PVD-applied AlTiN coating engineered for thermal resistance and extended tool life in demanding cutting applications. Machinists and toolroom professionals working with modular drilling systems will find this tip a direct-fit replacement component.

This replaceable drill tip is suited for use on CNC machining centers and drill presses where KTFS-series modular drill holders are in service. The HPG insert geometry and KCP15A grade make it appropriate for production drilling in steel, cast iron, and similar ferrous materials in both job shop and high-volume manufacturing environments. The seat size K designation must be matched to a compatible KTFS-series holder before installation.

Key Features

• 0.4134-inch (10.50 mm) cutting diameter for precise bore sizing
• 143-degree point angle for stable entry and reduced thrust force
• Solid carbide construction for rigidity and wear resistance
• KCP15A grade with PVD AlTiN coating for thermal and abrasion resistance
• HPG insert geometry for optimized chip evacuation
• Insert seat size K - matches KTFS-series modular drill body holders

Compatibility

Designed as a replaceable tip for KENNAMETAL KTFS-series modular drill bodies with an insert seat size K. Verify seat size and series compatibility against the holder specification before ordering.

Installation Notes

Replaceable drill tips of this type are installed and torqued by qualified machinists or toolroom personnel following the drill body manufacturer's assembly instructions. Power down and lock out the spindle before changing any cutting insert or tip component. Do not use damaged or contaminated seating surfaces, as improper seating can result in tip ejection or dimensional inaccuracy. Consult the holder manufacturer's torque and assembly documentation for correct installation procedure.
