Kennametal 5626721 Carbide Replaceable Tip Drill 21.43mm

Product Description

The KENNAMETAL 5626721 is a carbide replaceable tip drill insert from the KSEM Plus series, designed for high-performance drilling in steel and stainless steel applications. It carries the KCPM45 manufacturer grade with a fine grain solid carbide construction and a PVD-applied TiAlN coating for heat and wear resistance. The HPG insert geometry and 140-degree drill point angle support accurate entry and clean chip evacuation. With through-coolant capability including MQL (Minimum Quantity Lubricant) support, this tip is suited for use in production drilling environments where tool life and hole quality are critical. Installation and changeout are handled by licensed machinists and CNC operators.

This replaceable tip is used in drilling operations on steel and stainless steel workpieces, corresponding to ISO material codes P and M. It is designed for demanding applications including inclined surface entry, stacked plate drilling, and through-coolant drilling cycles. The KSEM Plus platform uses a clamped insert holding method with a size 3 insert seat, making it compatible with matching KSEM Plus drill bodies. The 2-flute, 2-margin helical flute configuration provides stable cutting and good hole finish across a range of feed and speed conditions.

Installation Notes

Replaceable tip drills of this type are installed and serviced by qualified machinists or CNC tooling technicians. Before changing the insert, ensure the machine spindle is fully stopped and locked out per shop lockout/tagout procedures. Use the correct clamping tool specified for the KSEM Plus platform to achieve proper seating torque — refer to the KENNAMETAL KSEM Plus tooling manual for procedure. Verify coolant passages are clear before returning the tool to service.
