Kennametal 7064676 Indexable Drill Insert Dfpr Carbide

Product Description

The KENNAMETAL 7064676 is a carbide indexable drill insert designed for use in modular indexable drilling systems. Manufactured to DFPR insert style geometry, this insert carries the KCMS35 manufacturer grade and features an AlTiN (aluminum titanium nitride) coating that extends tool life in demanding machining environments. The inscribed circle measures 0.304 inches (7.71 mm), thickness is 2.8 mm, and the corner radius is 0.019 inches (0.5 mm). It is seated and indexed by machining technicians and tool-room professionals during setup or insert replacement on compatible drill bodies.

This insert is suited for use in metalworking and machining operations where precision hole-making is required. The DFPR style and insert size code 07 place it in the Drill Fix series, targeting applications in steel, stainless, and other materials where AlTiN coating provides thermal and wear resistance. It is used in CNC machining centers, turning centers with live tooling, and manual production drilling setups. The MS chipbreaker geometry is optimized for medium-duty cutting conditions.

Key Features

• DFPR insert style with proprietary shape geometry and 11-degree relief angle
• KCMS35 grade carbide substrate with AlTiN coating for elevated wear and heat resistance
• MS chipbreaker for controlled chip formation in medium-duty drilling applications
• Inscribed circle of 0.304 inches (7.71 mm) with 0.019-inch corner radius for precise edge geometry
• ANSI and ISO code DFPR070305MSO for standardized identification and cross-reference
• Part of the Drill Fix series, engineered for repeatable indexing and consistent hole quality

Compatibility

Designed for use with DFPR-style compatible drill bodies. Verify drill body manufacturer specifications for insert size code 07 and DFPR seating geometry before installation.

Installation Notes

Insert indexing and replacement should be performed by qualified machining technicians with the spindle powered down and the machine in a locked-out, tagged-out state per applicable shop safety procedures. Use the appropriate torx or insert-clamping wrench specified by the drill body manufacturer - do not substitute tools that may damage the seating pocket or clamping mechanism. Inspect the insert pocket for wear or debris before seating a new insert. Follow the drill body manufacturer's torque and seating instructions for secure clamping.
