Kennametal 5981596 Replaceable Drill Tip 1.1220 in KCPM45

Product Description

The KENNAMETAL 5981596 is a replaceable drill tip designed for use with KSEM modular drill systems. It features a 1.1220-inch (28.00 mm) cutting diameter, a 140-degree drill point angle, and a solid carbide construction in fine-grain KCPM45 grade. The TiAlN coating is applied via PVD process, providing thermal resistance and wear protection during high-speed drilling operations. The FEG insert geometry supports efficient chip formation across a range of workpiece materials. This tip is installed and serviced by machinists, tool and die professionals, and CNC operators working in production or job-shop environments.

This replaceable tip is suited for drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, corresponding to ISO material codes P, M, K, N, and S. The KSEM series design supports flat-bottom drilling, counterboring, inclined entry and exit drilling, and cross-hole drilling. The straight flute configuration and clamp-style insert holding method make it appropriate for rigid, precision drilling setups on CNC machining centers and lathes with live tooling. Insert seat size 7 governs holder compatibility.

Key Features

• Solid carbide fine-grain KCPM45 grade for toughness and wear resistance
• TiAlN PVD coating for thermal and oxidation resistance at elevated cutting temperatures
• 140-degree drill point angle with FEG geometry for flat-bottom and cross-hole applications
• 2-flute, 4-margin straight-flute design for stable, precise entry and exit
• Clamp-style insert holding for secure seating and repeatable indexing
• Compatible with drilling in P, M, K, N, and S ISO workpiece material categories

Compatibility

Designed for use in KSEM series modular drill holders with insert seat size 7. Verify holder seat size before installation. ISO number KSEM2850FEGM identifies this tip within the KSEM platform.

Installation Notes

This replaceable tip is installed by machinists or CNC tooling technicians using the appropriate KSEM clamp-tightening tool. Ensure the machine spindle is fully stopped and the tool holder is secure before removing or seating the insert. Inspect the insert seat for chips or debris before installation to ensure full seating and accurate runout. Follow the tooling manufacturer's clamping torque guidance for the specific KSEM holder in use.
