Kennametal 6688293 Kentip Fs Indexable Drill Body 5/8 in

Product Description

The KENNAMETAL 6688293 is a KenTIP FS series indexable drill body with a straight cylindrical shank, designed for use with interchangeable carbide tip inserts in CNC machining and production drilling operations. The drill body features a 5/8 inch shank diameter, an overall length of approximately 4.61 inches (117 mm), and a flute length of approximately 1.85 inches (47.10 mm). Built around the KTFS toolholder style, this drill body supports through-coolant delivery to extend tool life and clear chips efficiently in high-volume drilling environments. Machinists and CNC operators working in job shops, aerospace, or general metalworking applications install this style of drill body.

The 6688293 is suited for production drilling where repeatable hole quality and fast tip changeover are priorities. The 3xD depth-to-diameter ratio makes it appropriate for moderate-depth holes in steel, cast iron, and similar workpiece materials. Through-coolant capability makes it well matched to harder materials and higher feed rates. The KTFS interface is specific to the KenTIP FS system, requiring compatible KenTIP FS carbide tips for proper assembly. A shank length of approximately 1.89 inches (48.00 mm) provides adequate retention in standard tool holders and collet chucks sized for 5/8 inch straight shanks.

Key Features

• 5/8 inch straight cylindrical shank for standard collet and toolholder mounting
• 3xD drill depth-to-diameter ratio for moderate-depth production drilling
• Through-coolant capability for improved chip evacuation and tool life
• Overall length of 117 mm (approximately 4.61 inches) with 47.10 mm flute length
• Lightweight construction at approximately 0.27 pounds for reduced spindle load

Compatibility

Designed for use within the KENNAMETAL KenTIP FS system, requiring compatible KenTIP FS carbide drill tips. Fits standard toolholders and collet chucks accepting a 5/8 inch straight cylindrical shank.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the drill body. Secure the shank in a properly sized collet or toolholder to the torque specification required by the toolholder manufacturer — do not rely on hand-tightening alone. Verify coolant port alignment when through-coolant is used, and confirm the KenTIP FS tip is fully seated and locked before initiating a cut.
