Kennametal 6388542 Replaceable Drill Tip 0.6535 in KCP15A

Product Description

The KENNAMETAL 6388542 is a replaceable drill tip designed for use with compatible indexable drill bodies in the KTFSS series. It carries the ISO designation KTFSS16600HPGM and is manufactured from solid carbide with a fine grain material grade. The tip features an AlTiN coating applied via PVD process, which supports thermal resistance and tool life in demanding metal-cutting applications. With a cutting diameter of 0.6535 inches, a 180-degree drill point angle, and HPG insert geometry, this tip delivers accurate entry and exit performance. It is held in place via a clamp-style insert holding method and fits seat size U. Intended for installation by machinists and tool-room technicians in production drilling environments.

This drill tip is suited for drilling operations in steel and cast iron workpieces, classified under material codes P and K. It supports specialty drilling applications including inclined exit drilling and stacked plate drilling, making it applicable in aerospace, automotive, and general metalworking contexts. The two-flute, two-margin helical configuration with regular spiral provides chip control and hole quality in through and blind-hole operations. Package quantity is one tip per unit.

Key Features

• Solid carbide construction with fine grain material grade for edge strength and wear resistance
• AlTiN coating via PVD process for thermal stability in steel and cast iron cutting
• 180-degree included point angle for flat-bottom entry and reduced thrust force
• HPG insert geometry optimized for inclined exit and stacked plate drilling applications
• Two-flute, two-margin helical design for chip evacuation and bore accuracy
• Clamp-style holding method with seat size U for secure, repeatable tip seating

Compatibility

Designed for use with KTFSS series indexable drill bodies accepting seat size U inserts. Compatible with primary workpiece materials including steel (ISO material code P) and cast iron (ISO material code K). Refer to the KENNAMETAL KTFSS series tooling catalog to confirm body compatibility before installation.

Installation Notes

This replaceable tip is installed by qualified machinists or toolroom personnel following the drill body manufacturer torque and seating procedures for the KTFSS platform. Power down and lock out the machine before changing inserts. Inspect the insert pocket and seating surfaces for chips or damage before installing the new tip. Do not reuse a tip that shows edge chipping, cratering, or deformation, as this can compromise hole quality and operator safety.
