Kennametal 7034364 Carbide Indexable Drill Insert KCU40

Product Description

The KENNAMETAL 7034364 is a carbide indexable drill insert designed for use with Drill Fix series indexable drilling systems. Manufactured to the DFPR insert style, it carries KENNAMETAL grade KCU40 with a dual-layer TiN and TiAlN coating for heat resistance and extended tool life in demanding hole-making operations. The inscribed circle measures 0.533 inches (13.55 mm), thickness is 0.173 inches (4.40 mm), and the corner radius is 0.031 inches (0.80 mm). The LC chipbreaker geometry promotes controlled chip formation during through-hole and blind-hole drilling. This insert is sold individually and is intended for installation by machinists and toolroom technicians working with compatible Drill Fix insert-style drill bodies.

This insert is suited for production drilling in ferrous and non-ferrous materials where repeatable hole quality and insert indexability are required. The right-hand cutting orientation and 11-degree relief angle make it appropriate for general-purpose drilling applications on CNC machining centers and turret lathes. The ANSI and ISO designation for this insert is DFPR140408LCO, which can be used to cross-reference equivalent inserts from other suppliers. Size code 14 identifies the insert within the Drill Fix system family.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or indexing any insert. Use the correct torx or insert-mounting screw specified by the drill body manufacturer and do not substitute fasteners. Inspect the insert pocket for chips or damage before seating a new insert to ensure proper support and accurate hole geometry.
