Kennametal 7064648 Indexable Drill Insert Dfpr Carbide

Product Description

The KENNAMETAL 7064648 is a carbide indexable drill insert designed for use in modular indexable drilling systems. Manufactured in the DFPR insert style and graded KCMS40, this insert features an AlTiN coating and an MS chipbreaker geometry engineered for controlled chip formation in a wide range of workpiece materials. The inscribed circle measures 0.3170 inches (8.04 mm), with a thickness of 2.8 mm and a corner radius of 0.0160 inches (0.4 mm). It belongs to the Drill Fix series and carries an ANSI and ISO code of DFPR080304MSI. Licensed machinists and tooling specialists install these inserts in CNC drilling operations.

This insert is suited for precision hole-making operations in production machining environments, including general metalworking, aerospace component drilling, and automotive part manufacturing. The DFPR insert style and insert size code 08 are specific to compatible modular indexable drill bodies that accept DFPR-style peripheral or inner insert seats. The AlTiN coating provides thermal resistance and extended tool life at elevated cutting speeds in ferrous and difficult-to-machine materials. The MS chipbreaker is optimized for medium-feed drilling conditions.

Key Features

• Carbide substrate with AlTiN coating for thermal resistance and extended wear life
• KCMS40 manufacturer grade suited for medium-duty drilling in a range of materials
• MS chipbreaker geometry promotes controlled chip evacuation at medium feed rates
• Corner radius of 0.0160 inches (0.4 mm) reduces edge chipping at entry and exit
• DFPR insert style with insert size 08 for direct compatibility with matching drill bodies
• Relief angle of 8 degrees supports stable cutting edge engagement

Compatibility

Designed for use with DFPR-style indexable drill bodies that accept size 08 inserts. Compatible drill style is DFPR as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body is removed from the spindle and fully de-energized before seating or indexing inserts. Use the correct torx or insert-clamping wrench to the drill body manufacturer's specified fastener procedure — do not overtighten by hand estimation. Inspect the insert pocket for debris or damage before seating a new insert, and confirm the insert is fully seated and locked before returning the tool to service.
