Kennametal 6388536 Replaceable Drill Tip KCP15A Altin

Product Description

The KENNAMETAL 6388536 is a replaceable drill tip designed for use with compatible indexable drill bodies in high-production machining environments. Built from fine grain solid carbide and coated with AlTiN via a PVD process, this tip delivers consistent cutting performance in demanding applications. It carries a cutting diameter of 0.6406 inches (11.11 mm), a 180-degree included point angle, and a standard HPG insert geometry. The KCP15A grade is matched to steel and cast iron workpiece materials. A licensed machinist or tooling technician installs and replaces this tip as part of a modular drill system.

This drill tip is suited for drilling operations in steel and cast iron, including inclined exit conditions and stacked plate configurations. Its helical flute design and regular spiral type promote chip evacuation during through-hole and blind-hole work. The two-flute, two-margin geometry supports dimensional accuracy in production drilling setups. It is clamped into an insert seat size U holder and does not require coolant-through capability, making it compatible with standard external coolant delivery setups.

Key Features

• Fine grain solid carbide substrate with KCP15A manufacturer grade
• AlTiN coating applied via PVD process for wear resistance in steel and cast iron
• 180-degree standard point angle with HPG insert geometry
• Two-flute, two-margin helical configuration for chip control
• Rated for inclined exit and stacked plate drilling applications
• Insert seat size U; clamp-style holding method

Compatibility

Designed as a replaceable tip for use with KTFSS series indexable drill bodies that accept insert seat size U. Compatible primary workpiece materials are steel (ISO material code P) and cast iron (ISO material code K).

Installation Notes

Installation and replacement of indexable drill tips should be performed by a qualified machinist or tooling technician. Ensure the drill body and spindle are fully de-energized and locked out before changing inserts. Use the appropriate torque wrench and clamping hardware specified by the drill body manufacturer; do not overtighten the clamping screw. Inspect the insert seat for wear or debris before seating the replacement tip.
