Kennametal 6388627 Replaceable Drill Tip 0.7677 in KCP15A

Product Description

The KENNAMETAL 6388627 is a replaceable drill tip designed for use with KTFSS-series indexable drilling systems. Manufactured from solid carbide with a fine grain material grade, this tip carries the KCP15A manufacturer grade and features a physical vapor deposition (PVD)-applied AlTiN coating for extended tool life in demanding cutting environments. The tip has a 0.7677 inch cutting diameter, a 180-degree drill point angle, and a helical flute geometry with an HPG insert profile. It is installed and replaced by machinists and tooling technicians on CNC machining centers and drill platforms requiring precise, repeatable hole quality.

This replaceable tip is suited for drilling operations in steel and cast iron workpieces, with ISO material codes P and K. The KTFSS series is engineered for applications including standard through-drilling, inclined exit drilling, and stacked plate drilling. The 2-flute, 2-margin configuration without coolant-through capability makes it appropriate for setups where external or flood coolant is used. Insert seat size X and the clamp holding method ensure rigid, repeatable seating in compatible KTFSS toolholders.

Key Features

• Solid carbide construction with fine grain material grade for rigidity and wear resistance
• KCP15A grade with PVD-applied AlTiN coating for thermal and abrasion resistance
• 180-degree standard point angle for flat-bottom entry and reduced thrust
• HPG insert geometry with helical, regular spiral flutes for chip evacuation
• Rated for steel and cast iron applications (ISO P and K workpiece materials)
• Compatible with inclined exit and stacked plate drilling applications

Compatibility

Designed for use with KTFSS-series indexable drill bodies requiring insert seat size X. Compatible toolholders must accept the KTFSS19500HPGM tip geometry and clamp-style insert holding method.

Installation Notes

Installation is performed by qualified machinists or tooling setup personnel. Power down and lock out the machine spindle before seating or removing any replaceable drill tip. Ensure the insert seat is clean and free of chips or debris before clamping to maintain proper seating and runout tolerances. Follow the toolholder manufacturer torque guidance for the clamp screw; do not over-torque.
