Kennametal 5067520 Indexable Drill Insert Dfthp KCU25

Product Description

The KENNAMETAL 5067520 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems in metal cutting and machining applications. This insert carries the DFTHP designation, indicating a trigon (84-degree included angle) shape with an HP chipbreaker geometry engineered to manage chip flow under high-feed drilling conditions. The KCU25 grade features a PVD-applied AlTiN coating, which provides thermal resistance and wear protection during ferrous and non-ferrous metal drilling. With a 10 mm (0.3937 inch) inscribed circle and a 1/32 inch corner radius, this insert is sized for precision fitment in compatible drill bodies. Installation and tool management are handled by machinists and CNC tooling specialists in production and job shop environments.

This insert is suited for indexable drill assemblies used in vertical machining centers, CNC lathes with live tooling, and dedicated drilling machines in both production and job shop settings. The neutral hand orientation makes it compatible with standard drill body configurations. It is typically applied in drilling operations on steel, stainless steel, and cast iron workpieces where controlled chip evacuation and extended tool life are required. The HP chipbreaker geometry is particularly effective in materials prone to long, stringy chip formation.

Key Features

• KCU25 grade solid carbide with PVD AlTiN coating for thermal and wear resistance
• HP chipbreaker geometry engineered for chip control in high-feed drilling
• Trigon shape with 84-degree included angle for balanced cutting forces
• 10 mm inscribed circle (0.3937 inch) for precise drill body fitment
• 1/32 inch (0.79 mm) corner radius reduces edge stress at drill entry
• Neutral hand insert for standard orientation drill body compatibility

Compatibility

Designed as a replacement-style indexable drill insert for KENNAMETAL DFTHP-series indexable drill bodies accepting insert size 06T308 with a 4.4 mm hole diameter. Confirm drill body insert pocket specifications before ordering.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine powered down and spindle locked. Use the correct torque wrench and insert screw per the drill body manufacturer's specification sheet — do not overtighten the clamping screw. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to installation.
