Kennametal 6389432 Indexable Drill Body Kentip Fs 8xd

Product Description

The KENNAMETAL 6389432 is an indexable drill body with a straight cylindrical shank, designed for use in the KenTIP FS (KTFS) toolholder system. This drill body accepts interchangeable cutting tips, allowing fast tip changes without removing the body from the spindle. It is built for deep-hole drilling operations at an 8xD depth-to-diameter ratio, making it well suited for machining centers and CNC lathes in production environments. The shank diameter is 3/8 inch, with an overall length of 126 millimeters and a flute length of 82.20 millimeters. Installation and setup are typically handled by machinists and tooling technicians in metal-cutting and precision machining applications.

This drill body is intended for metalworking operations where consistent hole quality and repeatable depth are required. The 8xD drilling depth capability makes it appropriate for applications that demand deeper bores relative to the drill diameter, such as structural components, fixture blocks, and manifold bodies. The KTFS toolholder style is specific to the KenTIP FS platform, which uses a self-centering tip seat for accurate tip indexing. This body is suited for both ferrous and non-ferrous workpiece materials when paired with the appropriate KenTIP FS cutting tip.

Key Features

Compatibility

Designed for use with the KENNAMETAL KenTIP FS (KTFS) series interchangeable drill tip system. Compatible tips must match the KTFS interface specification. Consult KENNAMETAL tooling catalogs to confirm correct tip selection for the target workpiece material and hole diameter.

Installation Notes

This drill body should be installed and secured by a qualified machinist or tooling technician familiar with indexable drilling systems. Ensure the machine spindle is fully stopped and locked out before mounting or changing the drill body or tip. Follow the machine tool manufacturer torque guidelines for the specific spindle interface, and verify tip seating before initiating any cutting cycle. Coolant-through capability should be confirmed at the machine interface prior to use in deep-hole operations.
