Kennametal 6388744 Replaceable Drill Tip 0.5000 in KCP15A

Product Description

The KENNAMETAL 6388744 is a replaceable drill tip designed for use with KTFSS-series modular drill bodies. Built from fine-grain solid carbide and coated with AlTiN via a PVD process, this tip delivers thermal resistance and edge durability in demanding drilling applications. The tip measures 0.5000 inches in cutting diameter with an overall projection of 0.3587 inches and a functional length of 0.2500 inches. The 180-degree included angle produces a flat entry point suited for flat-bottom drilling and precise hole entry. Grade KCP15A targets steel and cast iron workpiece materials. Licensed machinists and CNC operators install this tip into compatible KTFSS modular drill holders.

This replaceable tip is engineered for drilling operations in steel and cast iron, including inclined exit surfaces and stacked plate configurations. The helical, regular-spiral flute geometry in a 2-flute, 2-margin configuration promotes chip evacuation and hole finish quality. Seat size O governs holder compatibility. Coolant-through capability is not supported on this tip. Typical applications include precision hole-making on CNC machining centers and drill presses where repeatability and quick tip exchange reduce machine downtime.

Key Features

• Fine-grain solid carbide substrate for rigidity and wear resistance in ferrous materials
• AlTiN coating applied via PVD process for elevated heat resistance and extended tool life
• 180-degree point angle enables flat-bottom entry and reduces thrust on workpiece entry
• 2-flute, 2-margin helical geometry promotes chip flow and hole surface finish
• Rated for inclined exit and stacked plate drilling scenarios
• Replaceable tip design allows quick exchange without removing the drill body from the spindle

Compatibility

Designed for use with KTFSS-series modular drill holders accepting insert seat size O. Compatible primary workpiece materials are steel (ISO material code P) and cast iron (ISO material code K).

Installation Notes

Installation and replacement are performed by a qualified machinist or CNC tooling technician. Shut down spindle rotation and confirm the machine is in a safe, locked-out state before tip removal or installation. Use the appropriate torque wrench and KENNAMETAL-specified clamping hardware to seat the tip; do not over-torque the clamp screw, as carbide tips are brittle. Verify seat cleanliness before installation to ensure accurate seating and runout.
