Kennametal 6388714 Carbide Replaceable Tip Drill 11.5mm

Product Description

The KENNAMETAL 6388714 is a carbide replaceable tip drill designed for precision hole-making in metalworking applications. It carries the manufacturer part designation KTFSS11500HPGM and is built to the KCP15A grade with a solid carbide tip and a PVD-applied AlTiN coating for heat and wear resistance. The drill features a 143-degree included point angle and an HPG insert geometry, which supports aggressive chip evacuation and stable entry in interrupted or continuous cuts. Cutting diameter is 11.5 millimeters (0.4528 inches). The replaceable tip design reduces tooling cost by allowing tip exchange without discarding the entire drill body.

This drill is suited for production machining environments where consistent hole quality and extended tool life are required. Typical applications include drilling steel, stainless steel, and cast iron in CNC machining centers and drill presses running at programmed feeds and speeds. The KTFS series platform is intended for shops running high-volume operations that benefit from a standardized replaceable tip system. Installation is performed by machinists and toolroom technicians familiar with indexable and replaceable tip tooling systems.

Key Features

• Solid carbide tip construction for rigidity and edge retention in demanding materials
• AlTiN coating applied via PVD process for oxidation resistance and extended tool life at elevated cutting temperatures
• 143-degree included drill point angle with HPG insert geometry for controlled chip formation
• 11.5mm (0.4528 inch) cutting diameter with M-size insert seat
• Replaceable tip design reduces per-hole tooling cost compared to solid carbide drills
• No coolant-through configuration - suitable for external coolant or dry cutting setups

Compatibility

Designed for use within the KTFS series replaceable tip drill platform. The M insert seat size determines body compatibility. Verify seat size and series designation on the drill body before ordering replacement tips.

Installation Notes

Replaceable tip installation should be performed by a qualified machinist or toolroom technician using the appropriate torque tool specified for the KTFS body. Ensure the machine spindle is fully stopped and the tool is secured in a vise or tool holder before tip removal or installation. Inspect the insert seat for chips, contamination, or wear before seating a new tip. Follow the machine tool manufacturer and insert manufacturer guidelines for recommended feeds, speeds, and clamping procedure.
