Kennametal 6388596 Carbide Replaceable Tip Drill 8mm

Product Description

The KENNAMETAL 6388596 is a carbide replaceable tip drill designed for high-productivity hole-making in metalworking applications. Built around the KTFS series architecture, this drill accepts a solid carbide tip with an HPG insert geometry and an AlTiN coating applied via PVD process. The 143-degree included point angle is suited for work in harder materials where a more aggressive point geometry is required. The tip seat size is F, and the drill does not feature through-coolant capability. At 0.02844 pounds, it is a compact, lightweight tool intended for precision drilling operations performed by machinists and CNC setup technicians.

This replaceable tip drill is used in CNC machining centers and manual milling machines for drilling operations in steel, stainless steel, cast iron, and similar ferrous materials. The KCP15A grade designation indicates a PVD-coated carbide substrate optimized for these material classes. The KTFS series design allows the solid carbide tip to be replaced independently of the shank body, reducing tooling cost per hole when tips wear. Typical installations involve production machining environments where repeatability and tool life are critical factors.

Key Features

• Solid carbide tip with KCP15A grade for wear resistance in ferrous materials
• AlTiN coating applied by PVD process for heat and oxidation resistance
• HPG insert geometry with F seat size for precise tip seating and repeatability
• 143-degree included drill point angle suited for harder workpiece materials
• Replaceable tip design reduces total tooling cost compared to solid-shank drills
• Compact and lightweight at 0.02844 pounds for use in standard tool holders

Compatibility

Designed as an OEM-style replaceable tip for KTFS series drill bodies accepting an F seat size. Specific shank body compatibility should be verified against KENNAMETAL KTFS series tooling documentation before ordering.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or CNC technician. Power down and lock out the machine spindle before seating or removing the carbide tip. Use the correct torque wrench and manufacturer-specified tightening procedure for KTFS series tip seats to avoid cracking the carbide insert. Inspect the insert seat for chips or debris before installing a new tip.
