Kennametal 5068321 Indexable Drill Insert Dfthp KCPK10

Product Description

The KENNAMETAL 5068321 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal-cutting operations. It features the DFTHP insert style with a Trigon (84-degree included angle) geometry and an HP chipbreaker configuration optimized for high-performance drilling applications. The insert carries a KCPK10 manufacturer grade with a CVD-applied TiCN and Al2O3 coating for wear resistance and thermal stability. With a 12 mm inscribed circle (0.4724 inches) and a 0.3126-inch body length, this insert is sized for precision drilling in steel and cast iron workpieces. Installation is performed by machinists and CNC operators in production and job-shop environments.

This insert is suited for indexable drill tooling in CNC machining centers, turning centers with live tooling, and manual drilling operations requiring replaceable carbide cutting edges. The neutral hand designation makes it compatible with standard right-hand drill body holders. The HP chipbreaker geometry is particularly effective in drilling operations where chip control and evacuation are critical, such as deep-hole or interrupted-cut drilling in ferrous materials. The CVD coating process provides a dense, well-adhered coating layer that extends tool life in abrasive cutting conditions.

Key Features

• DFTHP insert style with 84-degree Trigon geometry for stable cutting geometry in drill bodies
• KCPK10 grade with CVD-applied TiCN and Al2O3 coating for wear resistance in ferrous materials
• HP chipbreaker designed for controlled chip formation and evacuation during drilling
• 12 mm inscribed circle (0.4724 inches) with 0.79 mm (0.0313 inches) corner radius
• Neutral hand orientation compatible with standard indexable drill holders
• 8-degree relief angle for reduced cutting force and improved surface finish

Compatibility

Designed as a replacement indexable drill insert for KENNAMETAL indexable drill bodies accepting DFTHP-style Trigon inserts with a 12 mm inscribed circle and 4.4 mm mounting hole diameter. Verify holder specifications against insert size designation 070408 before installation.

Installation Notes

Insert replacement is performed by machinists using the appropriate torx or hex key as specified by the drill body manufacturer. Always power down and lock out the machine spindle before accessing the insert pocket. Seat the insert fully into the pocket and confirm clamp engagement before resuming cutting operations. Do not exceed the cutting parameter recommendations of the drill body manufacturer for this insert grade and geometry.
