Kennametal 6389350 Kentip Fs Indexable Drill Body

Product Description

The KENNAMETAL 6389350 is a KenTIP FS series indexable drill body with a straight cylindrical shank, designed for deep-hole drilling applications in metal cutting and machining operations. Built to the KTFS toolholder style, this drill body accepts interchangeable KenTIP FS insert tips, allowing fast tip changes without removing the body from the spindle. The shank diameter is 1 inch, and the drill depth-to-diameter ratio is 8xD, making it well-suited for deep-hole work where rigidity and coolant delivery are critical. Through-spindle coolant is supported, helping to evacuate chips and manage heat at the cutting zone. The overall length is 294 millimeters, with a flute length of 224.50 millimeters and a shank length of 56.00 millimeters.

This indexable drill body is used in production machining environments including job shops, automotive component manufacturing, and general metalworking. It is intended for use in CNC machining centers and turning centers equipped with KTFS-compatible toolholding. The 8xD depth capability makes it appropriate for through-holes and deep blind holes where solid carbide drills may be cost-prohibitive or where the modular tip-swap system reduces downtime. Installation and operation are performed by machinists and CNC tooling specialists.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool is de-energized before mounting or removing the drill body. Follow the machine tool manufacturer torque and clamping specifications for the toolholder interface. Verify coolant port alignment when assembling the through-coolant system to ensure proper flow to the cutting zone.
