Kennametal 6388775 Replaceable Drill Tip 0.5469in KCP15A

Product Description

The KENNAMETAL 6388775 is a replaceable drill tip designed for use with compatible KTFSS-series indexable drill bodies. Manufactured from fine-grain solid carbide and coated with AlTiN via a PVD process, this tip delivers heat resistance and edge retention when drilling steel and cast iron. It carries the KCP15A manufacturer grade designation and features an HPG insert geometry with a 180-degree standard point angle. With a cutting diameter of 0.5469 inches and a helical, 2-flute design with 2 margins, it is suited to demanding metal-removal operations in production or job-shop environments. Licensed machinists and toolroom professionals are the primary installers.

This drill tip is intended for machining steel and cast iron workpieces in applications including standard drilling, inclined-exit drilling, and stacked-plate drilling. The HPG geometry and AlTiN coating support consistent performance in P- and K-group workpiece materials as defined by ISO material classification. The KTFSS series insert seat size Q clamp-hold design secures the tip to a matching KTFSS drill body shank for repeatable, tool-free tip exchanges at the machine without removing the body from the spindle.

Key Features

• Fine-grain solid carbide construction for rigidity and wear resistance in ferrous materials
• AlTiN coating applied via PVD process for elevated-temperature performance and extended tool life
• 180-degree standard point angle with HPG insert geometry for controlled entry and reduced thrust
• 2-flute, 2-margin helical design supports stable chip evacuation during through-feature drilling
• Rated for inclined-exit and stacked-plate drilling applications in addition to standard through-hole operations
• Insert seat size Q with clamp holding method for secure, repeatable tip indexing

Compatibility

Designed for use with KTFSS-series indexable drill bodies accepting insert seat size Q. Compatible primary workpiece materials are steel (ISO P) and cast iron (ISO K). The ISO number for this tip is KTFSS05469HPG.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before seating or removing the tip, power down the spindle and confirm the machine is in a safe, locked-out state. Use the correct torx or clamp key specified for the KTFSS body to seat the tip firmly against the insert pocket; do not overtighten by improvised means. Inspect the insert pocket seat for chips or debris before each tip change to ensure accurate seating and runout control.
