Kennametal 6389478 Kentip Fs Indexable Drill Body

Product Description

The KENNAMETAL 6389478 is a KenTIP FS series indexable drill body with a straight cylindrical shank, designed for use with interchangeable drill tips in precision hole-making operations. Built to the KTFS toolholder style, this drill body features a 16mm shank diameter and an overall length of 92mm. It is rated for a 1xD drill depth by diameter ratio, making it suited for shallow, high-accuracy drilling applications. The flute length measures 40.10mm with a shank length of 49.00mm. Machinists and CNC operators install this body on turning centers, machining centers, and drill presses where indexable tip systems are preferred over solid carbide.

This drill body is intended for metalworking environments where repeatable hole quality and fast tip changeover are required. The KenTIP FS platform uses a self-centering tip interface that maintains concentricity across tip replacements, reducing setup time in high-volume production. Typical applications include automotive component machining, die and mold work, and general precision metal removal. The straight cylindrical shank allows direct clamping in standard ER collet chucks, hydraulic chucks, or milling machine spindles without additional adapters.

Compatibility

Designed as an OEM-style replacement or production spare for KENNAMETAL KenTIP FS series indexable drilling systems using the KTFS toolholder interface.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and locked out before mounting or removing the drill body. Verify shank diameter tolerance and chuck bore condition before clamping to ensure runout specifications are met. Follow the toolholder manufacturer torque guidelines when securing the clamping mechanism, and confirm tip seating is fully engaged before initiating a cut.
