Kennametal 5067470 Indexable Drill Insert Dftgd KCU25

Product Description

The KENNAMETAL 5067470 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. It features the DFT insert style with a GD chipbreaker and is finished with an AlTiN (aluminum titanium nitride) coating applied via PVD process. The insert has an 8 mm (0.315 inch) inscribed circle, a thickness of 0.1476 inches, and a corner radius of 1/32 inch (0.0313 inches). Manufactured to the KCU25 grade, it is suited for demanding drilling applications where wear resistance and thermal stability are required. The neutral hand orientation makes it compatible with standard toolholder configurations.

This insert is intended for use in indexable drill bodies that accept the DFT insert style in size 05T308. The 84-degree trigon shape and 8-degree relief angle make it appropriate for general-purpose drilling in a range of workpiece materials. It is typically installed and serviced by machinists and tooling technicians in metalworking and production machining environments, including job shops and manufacturing facilities running CNC or manual drilling operations.

Key Features

• Solid carbide construction with AlTiN PVD coating for enhanced heat and wear resistance
• 8 mm inscribed circle with 84-degree trigon geometry and 8-degree relief angle
• GD chipbreaker design for controlled chip formation during drilling
• Corner radius of 1/32 inch (0.0313 inches) for edge strength
• Neutral hand insert compatible with standard DFT-style drill bodies
• Insert size 05T308 for consistent toolholder fit

Compatibility

Designed as an OEM-style replacement insert for indexable drill bodies that accept the DFT insert style in size 05T308 with an 8 mm inscribed circle.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body and pocket seating surfaces are clean and free of debris before seating the insert. Power down and de-energize the machine before any insert change. Follow the toolholder manufacturer's torque specifications for the clamping screw to avoid insert cracking or pocket damage.
