Kennametal 5397474 Replaceable Tip Drill 18mm KCPM45

Product Description

The KENNAMETAL 5397474 is a solid carbide replaceable tip drill in the KSEM Plus series, designed for high-productivity hole-making in steel and stainless steel applications. The tip carries the KCPM45 manufacturer grade with a fine-grain carbide construction and a PVD-applied TiAlN coating for heat and wear resistance. The cutting diameter is 18mm (0.7087 inches), the drill point angle is 140 degrees, and the helical flute design with 2 flutes and 2 margins promotes chip evacuation and hole quality. Through-coolant delivery, including MQL (Minimum Quantity Lubrication) compatibility, supports extended tool life in demanding cutting conditions. The tip mounts via a clamp-style insert holding method into an KSEM-compatible body.

This replaceable tip drill is suited for production machining environments where consistent hole tolerances and fast tip changes are priorities. Primary workpiece materials are steel (ISO P) and stainless steel (ISO M). The HPG insert geometry supports drilling into inclined surfaces, stacked plates, and through-coolant operations, making it a practical choice for job shops and high-volume manufacturers running CNC machining centers and drill presses with internal coolant capability.

Key Features

• 18mm (0.7087 inch) cutting diameter with 140-degree standard point angle
• Solid carbide KCPM45 fine-grain grade for strength and edge retention
• PVD TiAlN coating for thermal protection and extended tool life
• 2-flute, 2-margin helical geometry for chip control and hole finish quality
• Through-coolant and MQL compatible for dry or wet machining setups
• HPG insert geometry rated for inclined exit drilling and stacked plate applications
• Clamp-style tip retention for quick, repeatable tip changes without full body replacement

Compatibility

Compatible with KSEM Plus series drill bodies using insert seat size 1. Designed for use with CNC machining centers equipped with through-spindle coolant when running ISO P (steel) and ISO M (stainless steel) workpiece materials.

Installation Notes

Installation and tip changes should be performed by a qualified machinist following the toolholder manufacturer torque and seating guidelines for KSEM-style replaceable tip systems. Ensure the drill body bore and tip seating surfaces are clean and free of chips before seating the new tip. Disengage machine power and confirm spindle is fully stopped before any tip replacement. Verify coolant port alignment after tip installation when operating with through-coolant or MQL delivery.
