Kennametal 6388740 Replaceable Drill Tip 0.4921 in KCP15A

Product Description

The KENNAMETAL 6388740 is a replaceable drill tip designed for use with compatible KTFS-series modular drill bodies. It features a 0.4921-inch (12.50 mm) cutting diameter and a 143-degree included point angle optimized for the HPG insert geometry. The tip is manufactured from solid carbide and coated with AlTiN via a PVD process, delivering heat resistance and wear life in demanding drilling applications. This insert seat size O tip is intended for installation and replacement by machinists and tooling technicians working in metal-cutting environments.

This replaceable drill tip is suited for use in CNC machining centers and drilling operations where modular tooling systems are employed. The KTFS series platform allows fast tip changes without removing the drill body from the spindle, reducing downtime in production environments. It is applicable to drilling operations in steel, stainless steel, and similar ferrous workpiece materials where AlTiN coating provides a thermal barrier. This tip is a direct replacement component for the KTFS modular drill system in seat size O.

Key Features

• 0.4921-inch (12.50 mm) cutting diameter for precise bore sizing
• 143-degree drill point angle with HPG insert geometry for chip control
• Solid carbide substrate provides rigidity and edge retention
• AlTiN coating applied by PVD process for high-temperature and wear resistance
• Insert seat size O for direct fitment into compatible KTFS drill bodies
• No coolant-through design simplifies setup in standard drilling configurations

Compatibility

Designed as a replaceable tip for KTFS-series modular drill bodies requiring insert seat size O. Compatible drill bodies must accept the HPG geometry and O-seat specification.

Installation Notes

Installation is performed by qualified machinists or tooling technicians following the drill body manufacturer's torque and assembly procedures. Ensure the machine spindle is fully stopped and the tool is secured before removing or seating the tip. The seating surface on the drill body should be inspected and cleaned before installing a new tip to ensure proper seating and runout. Follow the toolholder manufacturer's clamping instructions for the KTFS seat interface.
