Kennametal 6688339 Kentip Fs Indexable Drill Body 8xd

Product Description

The KENNAMETAL 6688339 is a straight-shank indexable drill body from the KenTIP FS series, designed for deep-hole drilling applications in metal-cutting operations. Built to accept interchangeable KenTIP FS (KTFS) drill tips, this body eliminates the need to replace the entire tool when the cutting edge wears. It features a 5/8-inch straight cylindrical shank, an 8xD depth-to-diameter ratio for extended reach, and through-coolant capability to support high-productivity drilling cycles. Machinists and tooling specialists working on CNC machining centers and turning centers are the primary users of this tool body.

This drill body is suited for production drilling in shops running ferrous and non-ferrous workpiece materials where extended drill depth is required. The 8xD ratio makes it appropriate for applications such as deep bolt holes, fluid passages, and structural bores where standard 3xD or 5xD bodies fall short. Through-coolant delivery helps evacuate chips and manage heat at the cutting zone during high-feed drilling cycles.

Key Features

• KenTIP FS (KTFS) toolholder style accepts indexable drill tip inserts for quick changeover
• 8xD drill depth-to-diameter ratio for extended reach drilling
• 5/8-inch straight cylindrical shank for compatibility with standard collet chucks and hydraulic holders
• Through-coolant capability for improved chip evacuation and heat management
• Overall length of 180 mm with a flute length of 109.80 mm and shank length of 48.00 mm

Compatibility

Designed for use with KENNAMETAL KenTIP FS series interchangeable drill tips using the KTFS toolholder interface. Consult KENNAMETAL tooling documentation to confirm tip-to-body compatibility for specific drill diameters within this series.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully powered down and locked out before mounting or removing the drill body. Seat the shank fully in the collet or chuck and verify runout with a dial indicator before drilling. Follow the machine tool manufacturer torque specifications for the clamping system being used.
