Kennametal 2047440 Carbide Replaceable Tip Drill 26.59mm

Product Description

The KENNAMETAL 2047440 is a carbide replaceable tip drill in the KSEM series, designed for precision hole-making in steel and other P-category workpiece materials. The drill accepts a solid carbide tip with an HP insert geometry, secured by clamp-style holding, and carries a TiAlN coating applied via PVD process. The included angle is 140 degrees, and the cutting diameter measures 26.59mm (approximately 1-3/64 inches). With two helical flutes and a regular spiral, the 2047440 delivers consistent chip evacuation and stable cutting performance in production drilling environments. Licensed machinists and tooling technicians are the primary installers of this replaceable tip system.

This drill is engineered for steel machining applications where repeatable bore geometry and tool life are priorities. The KSEM platform supports drilling on inclined exit surfaces and stacked plate configurations, making it suited for structural, automotive, and general metalworking operations. The solid carbide tip seats in a size-6 insert seat and can be indexed or replaced at the spindle without removing the body from the toolholder. Two-flute, two-margin geometry provides bore straightness and surface finish appropriate for P-category steels.

Key Features

• Solid carbide HP insert geometry in KSEM size-6 insert seat
• TiAlN coating via PVD process for wear resistance in steel cutting
• 140-degree included angle for standard point entry and exit geometry
• Two helical flutes with two-margin design for bore accuracy
• Compatible with inclined exit and stacked plate drilling applications
• Clamp-style insert holding for secure tip retention under cutting loads

Compatibility

Designed for use with KSEM series replaceable tip drill bodies accepting a size-6 insert seat. Intended for P-category primary workpiece materials, principally steel. Compatible insert grade is KC7315 with fine grain carbide substrate.

Installation Notes

Installation and tip replacement should be performed by qualified machinists or tooling technicians following the machine tool manufacturer and Kennametal KSEM tooling assembly guidelines. Power down and lock out the spindle before seating or removing the carbide tip. Use the specified torque driver or clamping tool for the insert seat — do not use improvised tools that may damage the seating surface. Verify runout with a dial indicator after assembly before initiating a cut.
