Kennametal 6388602 Replaceable Drill Tip 0.3230 in KCP15A

Product Description

The KENNAMETAL 6388602 is a replaceable drill tip designed for indexable drilling systems where quick tip changes and consistent hole quality are required. Manufactured from fine-grain solid carbide and coated with AlTiN via a PVD process, it delivers extended tool life in demanding cutting environments. The tip measures 0.3230 inches (8.00 mm) in cutting diameter with a 180-degree included point angle and an HPG insert geometry. It carries manufacturer grade KCP15A, a designation suited for steel and cast iron applications. Two helical flutes and a regular spiral configuration support efficient chip evacuation during through and cross-hole drilling operations. Licensed machinists and CNC tooling specialists are the primary installers.

This drill tip is intended for drilling operations in steel and cast iron workpiece materials, covering ISO material codes P and K. The HPG geometry and AlTiN coating make it a practical choice for inclined-exit drilling, stacked-plate drilling, and standard through-hole operations. It mounts using a clamp-style insert holding method and fits an F-series insert seat. No coolant-through capability is present, so external or flood coolant delivery should be used when thermal management is a concern. The two-flute, two-margin design supports stable cutting at consistent feed and speed parameters.

Key Features

• Fine-grain solid carbide substrate for high hardness and wear resistance
• AlTiN coating applied via PVD process for elevated heat resistance and extended tool life
• 180-degree standard point angle for flat-bottom entry and consistent hole geometry
• HPG insert geometry engineered for steel and cast iron drilling
• Helical flutes with regular spiral for reliable chip evacuation
• Clamp-style holding method for secure seating in compatible indexable drill bodies

Compatibility

Designed for use with KTFSS-series indexable drill bodies accepting an F-series insert seat. Verify seat size and series designation on the drill body before installation.

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torque wrench and clamp screw specified by the drill body manufacturer - do not overtighten, as this can damage the carbide tip or the seat. Inspect the insert seat for chips or debris before installing a new tip, and confirm the seat size matches before applying clamping force.
