Kennametal 5397389 Carbide Replaceable Tip Drill 16.09mm

Product Description

The KENNAMETAL 5397389 is a carbide replaceable tip drill from the KSEM Plus series, designed for high-productivity drilling in steel and stainless steel applications. It carries the KCPM45 manufacturer grade with a fine grain solid carbide tip applied via PVD-deposited TiAlN coating. The drill features a 16.09mm (0.6335 inch) cutting diameter, a 140-degree drill point angle, and a helical flute configuration with two flutes and two margins. Coolant-through capability, including MQL (Minimum Quantity Lubricant) compatibility, supports chip evacuation and tool life in demanding production environments. Licensed HVAC, machining, and metalworking professionals recognize this series for its repeatable tip indexing without full body replacement.

This drill is suited for production drilling operations in ferrous materials, specifically steel and stainless steel (ISO material codes P and M). Typical applications include straight-entry drilling, inclined exit drilling, and stacked plate drilling. The HPG insert geometry and standard point type make it appropriate for through-hole and blind-hole work in both job shop and high-volume manufacturing environments. The KSEM Plus replaceable tip system reduces per-hole tooling cost compared to solid carbide drills by allowing tip replacement while retaining the drill body.

Key Features

• Solid carbide KCPM45 fine grain tip with PVD-applied TiAlN coating for wear resistance in steel and stainless steel
• 140-degree drill point angle with standard point type for accurate entry and exit
• Two-flute, two-margin helical design for balanced cutting forces and chip control
• Coolant-through design compatible with both flood coolant and MQL delivery systems
• Clamp-style insert holding for secure tip retention and repeatable positioning
• Rated for inclined exit and stacked plate drilling, expanding its range of production applications

Compatibility

Designed for use with the KSEM Plus replaceable tip drill body system; the insert seat size is 1 and the ISO insert number is KSEM0634HPG. Verify body compatibility by matching insert seat size before ordering tips separately.

Installation Notes

Replaceable tip installation and removal should be performed by a qualified machinist or tooling technician with the machine powered down and spindle locked. Use the manufacturer-recommended clamping tool for the KSEM Plus system to seat and secure the tip without over-torquing or cross-threading the clamp mechanism. Confirm coolant-through passages are clear before operation, particularly when switching between flood and MQL delivery. Follow applicable shop safety standards and machine tool manufacturer guidelines for high-speed drilling operations.
