Kennametal 6688316 Indexable Drill Body Kentip Fs 5xd

Product Description

The KENNAMETAL 6688316 is an indexable drill body with a straight cylindrical shank, designed for use in the KenTIP FS (KTFS) toolholder system. It features a 5xD drill depth-to-diameter ratio, allowing deep-hole drilling in a single pass without peck cycles on many applications. The shank diameter is 3/4 inch, the overall length is 167 millimeters, and flute length is 92.30 millimeters. Coolant-through capability is built in, supporting high-pressure coolant delivery directly to the cutting zone. This body accepts interchangeable KenTIP FS insert tips, making tip replacement fast without removing the body from the spindle. It is installed and used by machinists and CNC operators in production and job-shop environments.

The 6688316 drill body is suited for CNC machining centers, lathes with live tooling, and drilling fixtures where repeatable hole quality and fast cycle times are priorities. The 5xD depth ratio makes it appropriate for through-holes and blind holes in steel, cast iron, and similar workpiece materials where a standard 3xD drill body does not reach. The KTFS toolholder style is compatible with the KenTIP FS modular drill system, which separates the drill body from the cutting tip for cost-effective tip changes at depth.

Key Features

• 5xD drill depth-to-diameter ratio for deep-hole capability in a single body
• Straight cylindrical shank at 3/4 inch diameter for broad spindle and toolholder compatibility
• Coolant-through design delivers cutting fluid directly to the insert tip
• KTFS toolholder style integrates with the KenTIP FS modular insert tip system
• Flute length of 92.30 millimeters supports chip evacuation at full depth
• Shank length of 50.00 millimeters provides stable clamping in standard collet chucks and hydraulic holders

Compatibility

Designed for use with the KENNAMETAL KenTIP FS (KTFS) modular drill system, accepting KenTIP FS interchangeable insert tips. Requires a toolholder or spindle interface sized for a 3/4 inch straight cylindrical shank.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the drill body. Secure the straight shank in a collet chuck, hydraulic chuck, or milling chuck rated for the shank diameter, and verify runout with a dial indicator before operation. Follow the machine tool manufacturer and KENNAMETAL guidelines for coolant pressure settings and insert tip torque when seating the KenTIP FS tip into the body.
