Kennametal 6389276 Kentip Fs Indexable Drill Body

Product Description

The KENNAMETAL 6389276 is a KenTIP FS series indexable drill body with a straight cylindrical shank, designed for high-productivity drilling in metalworking and machining applications. It accepts KTFS-style indexable tip inserts, eliminating the need to replace the entire tool when the cutting edge wears. The body features through-coolant capability to manage heat and chip evacuation at the cutting zone. With a 5xD depth-to-diameter ratio and a 3/4-inch shank diameter, this drill body suits medium-depth hole-making operations on CNC machining centers and lathes. It weighs approximately 0.51 pounds.

This drill body is intended for use in production machining environments where consistent hole quality and reduced tooling cost per hole are priorities. It is suited for ferrous and non-ferrous metal drilling on CNC equipment with through-spindle or through-tool coolant supply. The KTFS toolholder style allows quick tip changes at the machine without removing the body from the spindle, reducing downtime during high-volume runs. Machinists and tooling engineers working in job shops, aerospace, automotive, and general manufacturing will find this body appropriate for recurring medium-depth drilling operations.

Compatibility

Designed for use with KTFS-style KenTIP FS series indexable drill tip inserts. Specific compatible tip part numbers were not provided in the available product data; consult KENNAMETAL tooling documentation to confirm the correct tip for your material and diameter requirements.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine in a locked-out state per OSHA lockout/tagout procedures. Ensure the shank is clean and properly seated in the chuck or collet before tightening to the machine manufacturer's recommended clamping specification. Verify through-coolant passages are clear before commencing drilling. Do not exceed the tool's rated depth-to-diameter ratio in a single plunge without confirming chip clearance.
