Kennametal 7034322 Carbide Indexable Drill Insert KC7140

Product Description

The KENNAMETAL 7034322 is a carbide indexable drill insert designed for use in modular indexable drill systems. It features the DFPR insert style with a proprietary shape and an 8-degree relief angle, making it suited for precision hole-making operations in metal cutting applications. The KC7140 manufacturer grade combines a TiN/TiCN/TiN multilayer coating to deliver wear resistance and thermal stability during drilling. The PK chipbreaker geometry promotes efficient chip evacuation, reducing the risk of chip packing in deep-hole drilling. This insert is installed and indexed by machining professionals in production and job-shop environments.

This insert fits the Drill Fix series of indexable drilling systems and is compatible with DFPR-style drill bodies. With an inscribed circle of 0.2090 inches (5.30 mm) and a thickness of approximately 0.094 inches (2.40 mm), it is sized for insert size code 05 applications. Typical use cases include through-hole and blind-hole drilling in ferrous and non-ferrous materials on CNC machining centers and lathes with live tooling. The ANSI and ISO code for this insert is DFPR050203PKI.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body is fully removed from the spindle and the machine is locked out before indexing or replacing inserts. Use the correct torx or clamp screw driver specified by the drill body manufacturer to achieve proper seating torque. Inspect the insert pocket for damage or debris before seating the new insert.
