Kennametal 6388702 Carbide Replaceable Tip Drill 11mm

Product Description

The KENNAMETAL 6388702 is a carbide replaceable tip drill designed for precision hole-making in metalworking applications. It carries the catalog designation KTFSS11000HPGM and belongs to the KTFS series. The cutting tip is solid carbide with an AlTiN finish applied via PVD coating, giving it strong resistance to heat and wear in demanding cutting conditions. The drill point is ground to a 143-degree included angle, suited for entry stability and chip control in a variety of workpiece materials. With an 11mm cutting diameter, this tool is a direct fit for applications requiring consistent, repeatable bore sizing. Installation and tip replacement are handled by machinists and tooling technicians in production and job-shop environments.

This drill is intended for use in CNC machining centers and drilling operations where a replaceable carbide tip body system is preferred over solid-shank drills. The KTFS platform allows the cutting tip to be swapped without removing the drill body from the spindle, reducing changeover time. The HPG insert geometry and KCP15A grade make it well suited for general-purpose metal drilling including cast iron, carbon steel, and alloy steel. Coolant-through capability is not supported on this configuration, so external or flood coolant is the appropriate method for chip evacuation and heat management.

Key Features

• Solid carbide cutting tip with AlTiN PVD finish for extended tool life in abrasive and high-heat cuts
• 143-degree drill point angle for stable entry and controlled chip formation
• 11mm cutting diameter with HPG insert geometry for consistent hole quality
• KCP15A manufacturer grade optimized for general-purpose metal drilling
• Replaceable tip design reduces tooling cost versus full solid-carbide drills
• Insert seat size L compatible with the KTFS series drill body platform

Compatibility

Designed as a replaceable tip insert for KTFS series drill bodies accepting an L-size insert seat. Verify body series and seat size before ordering to confirm fitment.

Installation Notes

Replaceable tip drills of this type are serviced by machinists or toolroom personnel. Power down and lock out the machine spindle before tip removal or installation. Use the appropriate torx or clamping key specified for the KTFS body to seat the tip securely. Do not exceed the recommended speed and feed parameters published by the manufacturer for the KCP15A grade and workpiece material combination.
