Kennametal 2047426 Carbide Replaceable Tip Drill Ksem

Product Description

The KENNAMETAL 2047426 is a solid carbide replaceable tip drill in the KSEM series, designed for precision hole-making in steel and similar ferrous workpiece materials. The tip carries a TiAlN coating applied via PVD process, which extends edge life under high heat and abrasion. The cutting diameter measures 13/16 inch (0.8126 inch, 20.64 mm) with a 140-degree drill point angle and a standard point type. The HP insert geometry combined with manufacturer grade KC7315 fine-grain solid carbide makes this tip well-suited for demanding production drilling applications where insert changeover speed and hole quality both matter.

This replaceable tip drill is intended for use in machining operations targeting steel workpieces, including through-hole and inclined-exit drilling scenarios as well as stacked-plate drilling. The KSEM platform uses an insert seat size 3 clamp-style holding method, allowing the carbide tip to be swapped without removing the drill body from the spindle in many setups. The two-flute, two-margin helical flute design supports chip evacuation and hole straightness in moderate-depth steel drilling. It is typically installed and serviced by machinists and tooling technicians in production or job-shop CNC environments.

Key Features

• Solid carbide KC7315 fine-grain grade tip with TiAlN PVD coating for extended tool life in steel
• 140-degree standard drill point angle reduces thrust and improves self-centering on entry
• HP insert geometry with insert seat size 3 and clamp-style holding for secure, repeatable tip seating
• Two-flute helical design with two margins supports chip flow and hole straightness
• Rated for inclined-exit and stacked-plate drilling applications
• Replaceable tip platform reduces tooling cost per hole versus solid carbide drills

Compatibility

Designed as an OEM-spec replaceable tip for KSEM series drill bodies using insert seat size 3. ISO number KSEM0813HP identifies the tip geometry and seat size for direct cross-reference when sourcing replacements.

Installation Notes

Installation and tip changes should be performed by qualified machinists or tooling technicians with the spindle fully de-energized and the machine in a safe, locked-out state. Use the correct torque wrench and clamping hardware specified for the KSEM seat size 3 system - do not substitute fasteners. Confirm tip seating and runout with a dial indicator before resuming production cuts. Coolant-through capability is not available on this tip; adjust cutting parameters and chip evacuation strategy accordingly.
