Kennametal 6389473 Indexable Drill Body Kentip Fs

Product Description

The KENNAMETAL 6389473 is a straight-shank indexable drill body from the KenTIP FS series, designed for use with interchangeable drill tip inserts in precision metal-cutting applications. The body features a 14mm straight-cylindrical shank and an overall length of 84mm, with a flute length of 33.9mm and a shank length of 46mm. This drill body is rated for a drill depth-to-diameter ratio of 1xD, making it suited for shallow, high-accuracy through and blind-hole drilling operations. It weighs approximately 0.32 pounds. Machinists and toolroom technicians working in production or job-shop environments are the primary users of this tool body.

This drill body is intended for use in CNC machining centers and turning centers where quick-change indexable tooling is standard. The KenTIP FS toolholder style (KTFS) is engineered for rigid, repeatable tip seating, reducing runout and improving hole quality in ferrous and non-ferrous workpiece materials. It is well-suited for applications requiring consistent performance across high-volume production runs where tip replacement without full body replacement is a priority.

Key Features

• KenTIP FS series (KTFS) toolholder style for secure, repeatable indexable tip interface
• 14mm straight-cylindrical shank for direct chuck or collet mounting
• 1xD drill depth-to-diameter ratio for shallow-hole drilling applications
• 33.9mm flute length supports effective chip evacuation at rated depth
• Overall length of 84mm suits compact spindle clearance requirements
• Lightweight at 0.32 pounds for reduced spindle load

Compatibility

Designed for use with KENNAMETAL KenTIP FS series indexable drill tip inserts compatible with the KTFS toolholder interface. Refer to KENNAMETAL tooling catalogs for specific insert grades and geometries matched to this body.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before mounting or removing the drill body. Verify that the collet or chuck bore matches the 14mm shank diameter and that clamping torque follows the machine tool manufacturer specifications. Inspect the tip pocket and seating surfaces for chips or debris before seating a new indexable tip.
