Product Description

The KENNAMETAL 7064646 is a carbide indexable drill insert designed for use in modular indexable drill systems requiring the DFPR insert style. Manufactured to the KCMS40 grade and finished with an AlTiN coating, this insert is engineered for demanding drilling operations where heat resistance and wear performance are critical. It features a proprietary shape with an 8-degree relief angle, a corner radius of 0.012 inches (0.3 mm), and an inscribed circle diameter of 0.2090 inches (5.30 mm). Thickness measures 2.4 mm. The MS chipbreaker geometry supports controlled chip evacuation across a range of workpiece materials.

This insert is intended for use in the Drill Fix series indexable drilling system and is suited for machining centers and CNC turning centers in production environments. Typical applications include through-hole and blind-hole drilling in steel, stainless steel, and similar ferrous materials. Installation is performed by qualified machinists or tooling specialists as part of a scheduled insert replacement cycle. Insert Size Code is 05, with an ANSI and ISO code of DFPR050203MSI.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the appropriate torx or hex key specified by the toolholder manufacturer to seat the insert — do not overtighten or substitute fasteners. Inspect the pocket seat for damage or debris before seating a new insert. Follow the toolholder manufacturer's clamping procedure to ensure correct indexing and runout.
