Kennametal 6688311 Indexable Drill Body Kentip Fs 5xd

Product Description

The KENNAMETAL 6688311 is a straight-shank indexable drill body from the KenTIP FS series, designed for through-coolant drilling operations in metalworking applications. The body accepts interchangeable KenTIP FS (KTFS) drill tip inserts, allowing fast tip changes without removing the tool from the spindle. It features a 5/8-inch straight cylindrical shank, a flute length of 71.80 mm, and an overall length of 142 mm. The 5xD depth-to-diameter ratio makes this body suited for moderate-depth hole-making in production environments. Weighing 0.287 pounds, it is a compact, lightweight tool body intended for CNC machining centers and drilling machines.

This drill body is used in precision hole-making operations on CNC machining centers, drill presses, and turning centers where indexable tooling is preferred over solid carbide or brazed-tip drills. The KenTIP FS platform is suited for drilling into steel, cast iron, stainless, and other common workpiece materials in both job shop and high-volume production settings. The straight cylindrical shank fits standard collet chucks, hydraulic chucks, and shrink-fit holders sized for 5/8-inch shanks. Installation and tool changes are performed by machinists and CNC setup technicians.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and all stored energy is released before mounting or changing the tool body or tip insert. Verify shank engagement depth meets the minimum grip length required by the toolholder manufacturer. Follow the tool manufacturer guidance for insert seating and clamping torque when installing the KenTIP FS tip insert into the body.
