Kennametal 6388834 Replaceable Drill Tip 0.626 in KCP15A

Product Description

The KENNAMETAL 6388834 is a replaceable drill tip designed for use in modular indexable drill systems. It is manufactured from solid carbide with a fine grain substrate and carries the KCP15A grade designation, a PVD-applied AlTiN coating, and an HPG insert geometry. The tip measures 0.6260 inches (16.00 mm) in cutting diameter and features a 180-degree drill point angle with a standard point type. It mounts into a size-T insert seat and is held in place by a clamp-style holding method. Machinists and tooling technicians install this tip as the cutting component in compatible KTFSS-series modular drill bodies.

This replaceable tip is suited for drilling operations in steel and cast iron workpiece materials, corresponding to ISO material groups P and K. It supports demanding application scenarios including drilling on inclined exits and through stacked plates. The helical, regular-spiral flute design with two flutes and two margins promotes chip evacuation and stable cutting in these conditions. It is intended for industrial machining environments where modular drill systems are used to reduce tooling cost and changeover time.

Key Features

• Solid carbide construction with fine grain substrate for wear resistance in ferrous materials
• KCP15A grade with PVD-applied AlTiN coating for thermal and oxidation resistance
• 180-degree drill point angle with HPG insert geometry for accurate entry and hole quality
• Two-flute, two-margin helical design supports chip evacuation in steel and cast iron
• Rated for inclined exit drilling and stacked plate drilling applications
• Clamp-style holding into size-T insert seat for secure, repeatable indexing

Compatibility

Designed for use with KTFSS-series modular drill bodies that accept a size-T replaceable tip seat. The ISO number for this tip is KTFSS15900HPGM. Verify seat size and series compatibility with the drill body before installation.

Installation Notes

Installation is performed by machining technicians familiar with indexable tooling systems. Before replacing the tip, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Use the correct torque wrench or clamping tool specified by the drill body manufacturer for the size-T seat - do not over-tighten by hand or with non-specified tools. Inspect the insert seat for debris or damage before seating the new tip to ensure proper seating and runout.
