Kennametal 6388540 Replaceable Drill Tip 0.6496 in KCP15A

Product Description

The KENNAMETAL 6388540 is a replaceable drill tip designed for use with compatible modular drill bodies in the KTFSS series. This solid carbide tip features a 180-degree point angle, helical flutes, and an AlTiN coating applied via PVD process. The ISO designation is KTFSS16500HPGM, and the tip carries a KCP15A grade in fine grain carbide. At 0.6496 inches (16.50 mm) cutting diameter and a functional length of 0.3248 inches, it is built for high-penetration drilling in steel and cast iron applications. Installation uses a clamp-style insert holding method with an Insert Seat Size U.

This replaceable tip is suited for drilling operations in ferrous materials, specifically steel (ISO P) and cast iron (ISO K). The HPG insert geometry supports use in demanding drilling scenarios including inclined exits and stacked plate configurations. It is intended for use in two-flute, two-margin modular drill systems without coolant-through capability. Machinists and tooling setups in production metalworking environments where repeatable tip changes reduce downtime will find this tip well-suited to their workflow.

Key Features

• Solid carbide construction in KCP15A fine grain grade for wear resistance in steel and cast iron
• AlTiN coating via PVD process for heat and oxidation resistance at the cutting edge
• 180-degree point angle with HPG insert geometry for consistent entry and exit
• Compatible with inclined exit and stacked plate drilling applications
• Clamp-style holding method with Insert Seat Size U for secure seating in KTFSS series bodies
• Regular spiral, helical flute design with 2 flutes and 2 margins

Compatibility

Designed for use with KTFSS series modular drill bodies accepting Insert Seat Size U. ISO number KTFSS16500HPGM. Intended for two-flute, two-margin drill body configurations without coolant-through porting.

Installation Notes

This tip is installed by a machinist or toolroom technician using the clamp-style retention method specific to the KTFSS modular drill system. Ensure the drill body is fully removed from the spindle and the machine is locked out before changing the tip. Inspect the insert seat for damage or debris before seating the new tip. Follow the drill body manufacturer torque guidance for the clamping screw, as no torque value is specified for this tip independently.
