Kennametal 5397481 Carbide Replaceable Tip Drill 19.5mm

Product Description

The KENNAMETAL 5397481 is a carbide replaceable tip drill in the KSEM Plus series, designed for high-performance hole-making in steel and stainless steel applications. The drill features a solid carbide tip with KCPM45 grade, fine grain material, and a TiAlN PVD coating that extends tool life under demanding cutting conditions. It measures 19.5mm (0.7677 inches) in cutting diameter and operates with a 140-degree drill point angle. The HPG insert geometry and helical flute design promote efficient chip evacuation. Through-coolant capability, including support for minimum quantity lubrication (MQL), allows use in both wet and MQL machining environments. Licensed machinists and CNC programmers typically specify and set up this tool.

This replaceable tip drill is suited for production drilling operations in machining centers and CNC lathes processing steel and stainless steel workpieces. The KSEM Plus platform is engineered for drilling on flat surfaces, inclined exits, and stacked plate configurations. With a 2-flute, 2-margin design and clamp-style insert holding, it delivers consistent positioning and repeatability across high-volume part runs. The insert seat size is 2, making it compatible with the corresponding KSEM Plus body series.

Key Features

• Solid carbide KCPM45 grade tip with fine grain microstructure for wear resistance
• TiAlN PVD coating for extended tool life in steel and stainless steel cutting
• 140-degree drill point angle with standard point type for clean entry and exit
• Through-coolant channels support both flood coolant and MQL delivery
• Helical, regular spiral flute design with 2 flutes and 2 margins for chip control
• Capable of drilling inclined exits and stacked plate configurations

Compatibility

Designed for use with KSEM Plus series drill bodies accepting insert seat size 2. Compatible with primary workpiece materials designated ISO material codes P (Steel) and M (Stainless Steel).

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and all motion axes at rest. Use the appropriate torque wrench and clamp hardware specified for the KSEM Plus insert seat to secure the replaceable tip before operation. Verify coolant passage alignment when through-coolant or MQL is in use. Do not exceed the cutting parameter ranges established in the KENNAMETAL KSEM Plus application guide for the selected workpiece material.
