Kennametal 6389275 Indexable Drill Body Kentip Fs 5xd

Product Description

The KENNAMETAL 6389275 is a straight-shank indexable drill body from the KenTIP FS series, designed for high-performance drilling in CNC machining centers and turning centers. It accepts indexable drill tips and provides a 5xD depth-to-diameter ratio, making it suited for moderate deep-hole drilling operations in a single pass. The 3/4 inch straight-cylindrical shank fits standard toolholders, and through-spindle coolant delivery is supported via internal coolant channels. With an overall length of approximately 6.57 inches and a flute length of approximately 4.48 inches, this body is built for shop-floor use by machinists and tool-crib professionals running production or job-shop drilling operations.

This drill body is used in metal-cutting applications including ferrous and non-ferrous materials across automotive, aerospace, die-and-mold, and general machining environments. The KenTIP FS toolholder style (KTFS) is compatible with the KenTIP FS insert tip family. It is appropriate for installations in horizontal and vertical machining centers where through-coolant capability is available and rigid, precise hole-location work is required. The straight-cylindrical shank allows clamping in standard chuck or collet systems without special adapters.

Key Features

• 5xD drill depth-to-diameter ratio for moderate deep-hole drilling in a single pass
• Straight-cylindrical shank at 3/4 inch diameter for broad toolholder compatibility
• Through-coolant capable to support chip evacuation and tool life at the cutting zone
• KTFS toolholder style designed for use with KenTIP FS indexable tip inserts
• Flute length of approximately 4.48 inches with a shank length of approximately 2 inches
• Lightweight body at approximately 0.47 pounds for reduced spindle load

Compatibility

Designed for use with the KenTIP FS series of indexable drill tip inserts using the KTFS toolholder interface. Specific compatible tip part numbers were not included in the available product data; consult KENNAMETAL tooling catalogs or technical support to confirm correct tip selection for your diameter and material application.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank in a properly sized chuck, collet, or hydraulic toolholder and verify runout before initiating a cut. Ensure the machine spindle coolant circuit is active and at the correct pressure before drilling when using the through-coolant feature. Do not exceed the depth capacity defined by the 5xD ratio without confirming chip clearance and tool integrity.
