Kennametal 6688306 Indexable Drill Body Kentip Fs 5xd

Product Description

The KENNAMETAL 6688306 is a straight-shank indexable drill body from the KenTIP FS series, designed for use with interchangeable carbide drill tips in CNC machining and production drilling applications. It features a 5/8-inch straight-cylindrical shank and a 5xD depth-to-diameter ratio, making it suited for moderate-depth hole-making operations. The toolholder style is KTFS, compatible with KenTIP FS insert tips. Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting zone for improved chip evacuation and tool life. This body is installed by machinists and CNC operators in job shop, production, and precision manufacturing environments.

This drill body is intended for use in CNC machining centers and turning centers where indexable drilling systems are preferred over solid carbide or brazed-tip tools. The 5xD depth ratio covers a wide range of general-purpose hole depths in steel, cast iron, and similar workpiece materials. With a flute length of 59.20 mm and an overall length of 130 mm, it fits standard tool-change configurations without requiring extended-reach setups. The KTFS toolholder style pairs with the corresponding KenTIP FS insert tip line for a complete drilling assembly.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool-change cycle is complete before handling or inserting the drill body. Secure the shank to the specified clamping torque per the machine tool manufacturer guidelines, and verify through-coolant connections are clear and properly seated before cycling the machine. Inspect the insert tip seating surface and clamping screw condition at each tip change.
