Kennametal 5981576 Replaceable Drill Tip 0.75 in Ksem

Product Description

The KENNAMETAL 5981576 is a replaceable drill tip designed for use in KSEM modular drill systems. Built from solid carbide in a fine grain material grade (KCPM45), it accepts a TiAlN coating applied via PVD process for extended wear resistance in demanding cutting applications. The tip measures 0.7500 inches in cutting diameter with an overall projection of 0.4070 inches and a functional length of 0.3750 inches. It features a 140-degree drill point angle, two straight flutes with four margins, and is secured by a clamp-style insert holding method. This tip is installed by machinists and tooling technicians in CNC drilling operations requiring repeatable, high-accuracy performance.

The 5981576 is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium (ISO material codes P, M, K, N, and S). It handles flat-bottom drilling, counterboring, inclined entry and exit drilling, cross-hole drilling, and standard through-hole drilling. The straight flute and flat point geometry make it well-suited for applications where bottom surface finish and entry stability are critical. Insert seat size 2 corresponds to compatible KSEM drill body holders.

Key Features

• Solid carbide construction in fine grain KCPM45 grade for toughness and edge retention
• TiAlN PVD coating for heat resistance and extended tool life in ferrous and exotic materials
• 140-degree drill point angle with flat point type for flat-bottom and cross-hole drilling
• Two straight flutes with four margins for improved hole geometry and surface finish
• Clamp-style insert holding for secure seating and fast tip replacement without body removal
• Compatible with inclined entry, inclined exit, and cross-hole drilling operations

Compatibility

Designed for use with KSEM modular drill bodies requiring an insert seat size 2 and the KSEM0750FEG insert geometry. ISO number KSEM0750FEG confirms fitment within the KSEM series platform.

Installation Notes

Installation is performed by qualified tooling technicians or machinists. Power down and lock out the machine spindle before replacing the drill tip. Use the appropriate clamp torque tool specified by the drill body manufacturer to seat the tip securely. Do not exceed the recommended spindle speeds and feeds for the workpiece material to avoid premature tip failure.
