Kennametal 5067479 Indexable Drill Insert Dftgd KCU25

Product Description

The KENNAMETAL 5067479 is a solid carbide indexable drill insert designed for use in indexable drill bodies requiring a Trigon (84-degree included angle) insert style. Manufactured to the DFTGD insert geometry with a KCU25 grade, this insert features a physical vapor deposition (PVD) AlTiN coating that improves heat and wear resistance during cutting operations. The inscribed circle measures 12 millimeters (0.4724 inches) and the insert thickness is 0.1875 inches. A GD chipbreaker geometry is incorporated to promote chip evacuation. This insert is installed by machinists and tooling technicians in production drilling applications.

This insert is suited for indexable drilling operations in metalworking environments where a neutral cutting direction and controlled chip formation are required. The DFTGD insert style fits compatible Kennametal indexable drill bodies designed for this geometry. Typical applications include hole-making operations in ferrous and non-ferrous materials where consistent insert indexing and secure clamping are critical to achieving repeatable bore quality.

Key Features

• Solid carbide substrate with PVD AlTiN coating for elevated wear and heat resistance
• KCU25 manufacturer grade for demanding drilling applications
• GD chipbreaker for controlled chip formation and evacuation
• Trigon shape with 84-degree included angle and neutral cutting direction
• 12 millimeter inscribed circle with 0.79 millimeter corner radius
• Insert size 070408 with 0.1732-inch hole diameter for secure clamping

Compatibility

Designed for use in Kennametal indexable drill bodies that accept the DFTGD insert style and 070408 insert size designation. Confirm tool body specifications against insert geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key to the tool body manufacturer's specified seating procedure to ensure the insert is fully seated and clamped. Inspect the insert pocket for damage or debris before installing a new insert.
