Kennametal 7064663 Indexable Drill Insert Dfpr Carbide

Product Description

The KENNAMETAL 7064663 is a carbide indexable drill insert designed for use with DFPR-style indexable drill bodies. Manufactured to grade KCMS40 with an AlTiN coating, this insert is engineered for demanding drilling operations in steel and similar workpiece materials. It features the MS chipbreaker geometry, which promotes controlled chip formation during deep-hole and through-hole drilling cycles. The insert has an inscribed circle of 0.807 inches (20.50 mm), a thickness of 6.2 mm, and a relief angle of 8 degrees. It is sized to insert size code 20 and carries ANSI and ISO code DFPR200608MSI. Machinists and tooling specialists in metalworking shops install and index these inserts during scheduled tool changes on CNC or manual drilling equipment.

This insert is suited for production drilling applications in metal fabrication, job shop, aerospace, and general machining environments. It seats into DFPR-compatible indexable drill bodies and is intended for use wherever controlled chip evacuation and wear resistance are priorities. The Drill Fix series designation indicates compatibility with KENNAMETAL Drill Fix indexable drill platforms. No additional grinding or modification is required at installation.

Key Features

• Carbide substrate with AlTiN coating for heat and wear resistance in ferrous materials
• KCMS40 manufacturer grade optimized for steel cutting applications
• MS chipbreaker geometry for predictable chip control
• Insert size 20 with ANSI/ISO code DFPR200608MSI for straightforward cross-reference
• Relief angle of 8 degrees for reduced cutting force at the insert edge
• Corner radius of 0.032 inches (0.8 mm) for edge stability during entry and exit

Compatibility

Designed for use with DFPR-style indexable drill bodies in the KENNAMETAL Drill Fix series. Compatible drill style designation is DFPR.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The drill body and spindle must be fully de-energized and locked out before insert indexing or replacement. Use the appropriate torx or hex key specified by the drill body manufacturer when seating the insert screw — do not overtighten. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and runout.
