Kennametal 5118456 Indexable Drill Insert Dfchp KCU40

Product Description

The KENNAMETAL 5118456 is a solid carbide indexable drill insert designed for use in indexable drill systems requiring precise, repeatable hole-making performance. The insert features a DFC style geometry with an HP chipbreaker and a 90-degree included angle, suited for moderate-to-aggressive drilling applications in ferrous and non-ferrous materials. It carries a PVD-applied TiN/TiAlN dual-layer coating in the KCU40 manufacturer grade, which supports wear resistance and thermal stability during interrupted or continuous cuts. The corner radius measures 0.031 inches (0.79 mm), and the insert thickness is 0.2067 inches. Installation is performed by qualified machinists or tooling technicians in CNC or manual drilling operations.

This insert is applied in indexable drilling operations across production machining, job shop, and manufacturing environments. The DFC insert style and HP chipbreaker combination is suited for drilling in steels, cast irons, and similar work materials where chip control and edge stability are priorities. The neutral hand orientation makes it compatible with center or peripheral insert positions depending on the drill body specification. Insert size designation is 090520, and the hole diameter for mounting is 0.2165 inches (5.5 mm). Typical use cases include through-hole and blind-hole drilling at moderate feed and speed parameters consistent with KCU40 grade recommendations.

Key Features

• Solid carbide substrate with PVD TiN/TiAlN dual-layer coating for thermal and wear resistance
• DFC insert style with HP chipbreaker geometry for controlled chip evacuation
• 90-degree included angle suits standard drilling geometry requirements
• 0.031-inch (0.79 mm) corner radius for edge strength in varied work materials
• Neutral hand orientation compatible with center and peripheral insert positions
• KCU40 manufacturer grade balanced for toughness and cutting performance

Compatibility

Designed as an OEM-style replacement indexable drill insert for indexable drill bodies accepting the 090520 insert size with a 0.2165-inch mounting hole diameter. Confirm insert style, hand, and seat geometry against the drill body specification before ordering.

Installation Notes

Indexable drill inserts are seated and secured by qualified machinists or CNC tooling technicians. Ensure the spindle and machine are fully powered down and locked out before removing or indexing inserts. Use a calibrated torque screwdriver appropriate for the insert screw specification to avoid seat damage. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
