Kennametal 6389423 Indexable Drill Body Kentip Fs 5xd

Product Description

The KENNAMETAL 6389423 is a straight-shank indexable drill body in the KenTIP FS series, designed for use with interchangeable carbide drill tips in precision hole-making operations. The body features a 3/8 inch straight-cylindrical shank and a 5xD depth-to-diameter ratio, making it suited for drilling applications that require moderate hole depth with high positional accuracy. The flute length measures 55.20 mm and the shank length is 40.39 mm, with an overall length of 99 mm. Weighing 0.07 pounds, this compact drill body is engineered for rigidity and repeatable tip seating in high-production machining environments. It is installed by machinists and tooling technicians in CNC and conventional drilling setups.

The 6389423 is designed for use in metal cutting applications where indexable-tip drilling provides a cost-effective alternative to solid carbide drills. The KenTIP FS system uses a self-locking tip interface that allows fast tip changes at the machine without removing the body from the spindle. This makes it well suited for production shops, job shops, and maintenance machining environments handling steel, cast iron, and similar workpiece materials. The KTFS toolholder style designation is used to match compatible tip inserts within the KenTIP FS product family.

Compatibility

Designed for use with KenTIP FS series indexable drill tips using the KTFS interface. Compatible tips must match the drill body diameter and series designation. Refer to KENNAMETAL KenTIP FS series documentation to confirm correct tip selection for this body.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body or changing the indexable tip. Seat the shank fully into the toolholder and verify clamping torque per the machine and toolholder manufacturer specifications. Inspect the tip seating pocket for chips or debris before each tip change to maintain positional accuracy and prevent premature tip or body wear.
