Kennametal 6388828 Replaceable Drill Tip 0.4219in KCP15A

Product Description

The KENNAMETAL 6388828 is a replaceable drill tip designed for use with compatible KTFSS-series modular drilling systems. Manufactured from fine grain solid carbide with a KCP15A grade and PVD-applied AlTiN coating, this tip delivers wear resistance and thermal stability during demanding drilling operations. It features a 180-degree point angle with an HPG insert geometry and a helical, regular-spiral flute design with two flutes and two margins. The insert seat size is T, and the tip is held in place by a clamp mechanism. Machining professionals and toolroom technicians working with steel and cast iron will find this tip suited for precision modular drilling setups.

This replaceable tip is intended for use in applications involving standard drilling, inclined-exit drilling, and stacked-plate drilling. The two-flute, two-margin, no-coolant-through configuration makes it appropriate for setups where internal coolant delivery is not required. Primary workpiece materials are steel and cast iron, corresponding to ISO material groups P and K. It is packaged individually and sold in single-unit quantities.

Key Features

• Fine grain solid carbide construction in KCP15A grade for strength and wear resistance
• PVD-applied AlTiN coating for thermal stability and extended tool life in steel and cast iron
• 180-degree point angle with HPG insert geometry for accurate entry and exit
• Two-flute, two-margin, regular helical spiral design without coolant-through
• Clamp-held insert seat size T for secure, repeatable positioning in KTFSS-series holders
• Rated for inclined-exit and stacked-plate drilling applications

Compatibility

Designed for use with KTFSS-series modular drill bodies that accept insert seat size T replaceable tips. Suitable for primary workpiece materials classified under ISO material groups P (steel) and K (cast iron).

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before removing or installing any replaceable tip. Use the appropriate torque wrench and clamping hardware specified by the holder manufacturer - do not overtighten or substitute fasteners. Inspect the seat and clamping surfaces for debris or wear before seating the new tip to ensure proper contact and runout accuracy.
