Kennametal 6388420 Carbide Replaceable Tip Drill 16mm Ktfs

Product Description

The KENNAMETAL 6388420 is a carbide replaceable tip drill designed for precision hole-making in metalworking and machining applications. This drill carries the manufacturer part number KTFSS16000HPGM and operates within the KTFS series platform, accepting U-seat insert tips with HPG geometry. The cutting tip is manufactured from solid carbide with an AlTiN (aluminum titanium nitride) coating applied via a PVD process, providing thermal resistance and wear life in demanding cutting conditions. The drill point is ground to a 143-degree included angle, which suits flat-bottomed or near-flat entry characteristics common in production drilling environments. Qualified machinists and CNC operators install this tooling in machining centers and CNC turning equipment.

This replaceable tip drill is suited for production machining environments where consistent hole quality and quick tip changeout are priorities. The KTFS platform allows operators to swap worn carbide tips without removing the drill body from the machine, reducing downtime on high-volume drilling operations. Typical applications include ferrous and non-ferrous metal drilling at the 16mm cutting diameter. The KCP15A grade and AlTiN coating make this tip a strong candidate for dry or light-coolant cutting strategies in steel and cast iron. Note that this drill body does not feature coolant-through capability.

Key Features

• 16mm (0.6299 inch) cutting diameter for precise, repeatable hole sizing
• Solid carbide tip construction in KCP15A grade for wear resistance in metal cutting
• AlTiN coating applied via PVD process for elevated thermal and oxidation resistance
• 143-degree drill point angle for near-flat entry and reduced thrust forces
• HPG insert geometry with U-seat sizing for compatibility within the KTFS replaceable tip system
• No coolant-through design - suited for dry or flood-from-outside cutting setups

Compatibility

Designed as a replaceable tip drill within the KENNAMETAL KTFS series platform, accepting U-seat carbide tips with HPG geometry. Specific body compatibility should be confirmed against KENNAMETAL KTFS series drill body documentation prior to ordering.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or tooling technician following the drill body manufacturer's torque and seating specifications for the KTFS platform. Power down and lock out the machine spindle before handling or changing any cutting tip. Use the appropriate KENNAMETAL torx or clamping key as specified for the U-seat insert to avoid tip seating issues. Do not exceed the recommended cutting parameters for the KCP15A grade - consult the manufacturer's speed and feed tables for the specific workpiece material.
