Kennametal 6688277 Indexable Drill Body Kentip Fs 3xd

Product Description

The KENNAMETAL 6688277 is a straight-shank indexable drill body from the KenTIP FS series, designed for use with interchangeable carbide drill tips in CNC machining and precision drilling applications. The body accepts KTFS-style tips and features through-coolant capability, allowing cutting fluid to reach the cutting zone directly for improved chip evacuation and tool life. With a 5/8 inch straight-cylindrical shank diameter and a 3xD depth-to-diameter ratio, this drill body suits medium-depth hole-making operations on machining centers and turning centers. Installation is performed by qualified machinists familiar with indexable tooling systems.

This drill body is suited for production environments requiring repeatable, close-tolerance hole geometry without the regrind cycles associated with solid drills. The KenTIP FS platform uses a front-loading tip interface, making tip changes fast at the machine. Typical applications include structural steel, cast iron, aluminum alloy, and general engineering materials in job shop and high-volume manufacturing settings. The compact overall length of 108 mm supports use in setups with limited Z-axis clearance.

Key Features

• KenTIP FS series with KTFS toolholder style for fast, repeatable tip indexing
• Through-coolant design directs fluid to the cutting edge for chip control and heat management
• 3xD drill depth-to-diameter ratio for medium-depth hole production
• 5/8 inch straight-cylindrical shank for compatibility with standard ER and hydraulic chuck toolholders
• Flute length of 37.20 mm and shank length of 48.00 mm for balanced reach and rigidity
• Lightweight construction at approximately 0.24 pounds for reduced spindle load

Compatibility

Designed for use with KTFS-series KenTIP FS interchangeable drill tips within the KENNAMETAL KenTIP FS platform. Compatible toolholders must accommodate a 5/8 inch straight-cylindrical shank.

Installation Notes

Installation and tip changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Ensure the shank bore of the toolholder is clean and free of chips before clamping. Follow the machine tool manufacturer torque specifications for the clamping mechanism used. Verify tip seating and runout with a dial indicator before beginning a production run.
