Kennametal 5067403 Indexable Drill Insert Dftmd KCU25

Product Description

The KENNAMETAL 5067403 is a solid carbide indexable drill insert designed for use in indexable drilling operations requiring consistent edge performance and dimensional accuracy. It carries the KCU25 manufacturer grade and features an AlTiN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding drilling applications. The insert is Trigon-shaped with an 84-degree included angle, a 6 mm (0.2362 inch) inscribed circle, and a corner radius of 0.40 mm (1/64 inch). Thickness measures 0.1160 inches and length measures 0.1563 inches. This insert is installed by machinists and tooling technicians in production machining environments.

This insert is suited for indexable drill toolholders that accept the DFTMD insert style with a Trigon geometry. Typical applications include through-hole and blind-hole drilling in metalworking operations across production and job-shop environments. The neutral cutting direction makes it appropriate for standard drill configurations. The MD chipbreaker designation indicates a medium-duty chipbreaker geometry, making it a fit for a range of ferrous and non-ferrous materials common in general machining. The hole diameter of 0.1043 inches (2.65 mm) accommodates the corresponding mounting screw.

Key Features

• Solid carbide construction for rigidity and wear resistance in drilling applications
• AlTiN coating via PVD process provides heat resistance and extended cutting life
• KCU25 grade optimized for indexable drilling with consistent insert-to-insert repeatability
• MD chipbreaker geometry supports chip control across medium-duty drilling conditions
• 84-degree Trigon shape with 8-degree relief angle for reduced cutting forces
• Neutral cutting direction compatible with standard drill body configurations

Compatibility

Designed for use in DFTMD-style indexable drill toolholders that accept a Trigon insert with a 6 mm inscribed circle and insert size 030304. Confirm toolholder insert pocket specifications before ordering.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or indexing any insert. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer's specified value. Inspect the insert pocket and clamping hardware for wear or damage before installing a new insert.
