Kennametal 6389406 Indexable Drill Body Kentip Fs 3xd

Product Description

The KENNAMETAL 6389406 is an indexable drill body with a straight cylindrical shank, designed for use in the KenTIP FS tooling system. It accepts interchangeable drill tips, allowing worn cutting edges to be replaced quickly without removing the drill body from the spindle. Built for precision metal-cutting applications, this drill body features a 3xD depth-to-diameter ratio, a 3/8-inch shank diameter, and a flute length of 41.20 mm. The overall length is 84 mm, with a shank length of 40.39 mm. Machinists and toolroom technicians working in production or job-shop environments will find this body compatible with standard KTFS-style tip inserts.

This indexable drill body is suited for use in CNC machining centers, turning centers with live tooling, and manual milling machines capable of accepting straight cylindrical shanks. The 3xD ratio makes it appropriate for through-hole and blind-hole drilling operations in steel, cast iron, and similar workpiece materials where moderate drilling depth is required. It is intended for professional machine operators and tooling specialists in industrial manufacturing environments.
