Kennametal 6388558 Replaceable Drill Tip 0.6772 in KCP15A

Product Description

The KENNAMETAL 6388558 is a solid carbide replaceable drill tip designed for indexable drill systems requiring a 0.6772-inch (17.20 mm) cutting diameter with a 180-degree point angle. Manufactured to the KTFSS series standard, this tip features an HPG insert geometry and an AlTiN coating applied via PVD process, both of which contribute to thermal resistance and edge retention during high-throughput drilling operations. The KCP15A fine-grain carbide grade is suited for demanding ferrous materials. It seats in a Size V insert pocket and is held by clamp-style retention. Installation is handled by machining professionals and CNC tooling specialists.

This replaceable tip is designed for drilling applications in steel and cast iron workpieces, making it appropriate for job shops, production machining centers, and maintenance machining environments. The helical flute configuration supports chip evacuation in through-hole and blind-hole operations. It is specifically suited for inclined exit drilling and stacked-plate drilling scenarios where stable entry and consistent geometry are critical. The regular spiral and 2-flute, 2-margin design provides balanced cutting forces across the full cutting diameter.

Key Features

• 0.6772-inch (17.20 mm) cutting diameter in KTFSS series insert geometry HPG
• 180-degree included point angle for flat-bottom and standard through-hole drilling
• AlTiN coating via PVD process for thermal resistance and extended tool life in ferrous materials
• KCP15A fine-grain solid carbide grade optimized for steel and cast iron (ISO material codes P and K)
• Helical flute, regular spiral, 2-flute/2-margin design for balanced chip control
• Compatible with inclined exit and stacked-plate drilling applications
• Clamp-style insert retention in Size V seat for repeatable tip indexing

Compatibility

Designed as a replaceable tip for KTFSS series indexable drill bodies accepting a Size V insert seat. Confirmed primary workpiece materials are steel and cast iron. No coolant-through capability; verify drill body compatibility before installation.

Installation Notes

Installation should be performed by qualified machining or tooling professionals familiar with indexable drill systems. Power down and lock out the machine spindle before seating or removing the drill tip. Use the appropriate torx or clamp key specified by the drill body manufacturer to secure the insert to the correct clamping torque per the tool body documentation. Do not exceed the drill body speed and feed recommendations for the KCP15A grade in the target workpiece material.
