Kennametal 5981589 Drill Tip 1 in 140 Deg KCPM45 Ksem

Product Description

The KENNAMETAL 5981589 is a solid carbide replaceable drill tip designed for use in KSEM modular drill systems. The tip measures 1.0000 inches in cutting diameter with a 140-degree included angle and a flat point geometry. It is manufactured from fine grain solid carbide in grade KCPM45 and carries a PVD-applied TiAlN coating for thermal resistance and extended tool life. The insert seat size is 5, and the tip mounts via a clamp-style holding method. Machinists and CNC operators install this tip as a field-replaceable cutting element, reducing downtime compared to full-tool replacement.

This drill tip is suited for drilling operations in a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. The FEG insert geometry supports flat-bottom drilling, counter-boring, cross-hole drilling, inclined entry, and inclined exit applications. The straight flute and straight spiral design contribute to stable chip evacuation in these demanding operations. It is intended for use in production machining environments on CNC turning centers and machining centers.

Key Features

• 1.0000 inch cutting diameter with 140-degree flat point angle for flat-bottom and through-hole applications
• Fine grain solid carbide substrate in grade KCPM45 for toughness and wear resistance
• PVD TiAlN coating for high-temperature resistance during steel and stainless steel drilling
• FEG geometry supports flat-bottom drilling, counter-boring, cross-hole, and inclined entry and exit
• Clamp-style insert holding method for secure, repeatable seating in KSEM toolholders
• 2-flute, 4-margin design for enhanced hole quality and guidance

Compatibility

Designed for use with KSEM modular drill bodies accepting insert seat size 5. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium per ISO codes P, M, K, N, and S.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing the insert tip. The clamping mechanism should be engaged per the toolholder manufacturer torque guidance using the appropriate KSEM torx or hex key. Inspect the insert seat for chips or debris before seating the new tip to ensure proper contact and runout.
