Kennametal 6389333 Kentip Fs Indexable Drill Body

Product Description

The KENNAMETAL 6389333 is a KenTIP FS series indexable drill body with a straight cylindrical shank, designed for use with interchangeable carbide drill tips in CNC machining and production drilling operations. The body features a 1-inch shank diameter and a 3xD drill depth-to-diameter ratio, making it well-suited for moderate-depth hole-making applications. Coolant-through capability is built in, allowing high-pressure coolant delivery directly to the cutting zone for chip evacuation and thermal control. The toolholder style is KTFS, compatible with the KenTIP FS insert system. Machinists and tool-crib technicians working in metalcutting environments are the primary users.

This drill body is intended for use in CNC machining centers, lathes with live tooling, or other machine tool setups that accept straight-cylindrical shank toolholders. The 3xD ratio suits through-hole and blind-hole drilling in steel, cast iron, aluminum, and similar workpiece materials where moderate depth is required. The KenTIP FS platform is a modular system that separates the drill body from the cutting tip, allowing tip replacement without removing the body from the spindle, which reduces downtime in high-volume production environments.

Designed for use with the KENNAMETAL KenTIP FS modular drilling system using KTFS-style toolholders and compatible KenTIP FS insert tips. No additional specific compatible model numbers were stated in the product data.

Installation Notes

Installation is performed by machining professionals in CNC toolroom or production environments. Ensure the machine spindle is powered down and locked out before mounting or removing the drill body. Verify shank seating and runout with a dial indicator before production use. Confirm coolant-through passages are clear and that machine coolant pressure is within the tool system specification before operating.
