Kennametal 6389335 Indexable Drill Body Kentip Fs

Product Description

The KENNAMETAL 6389335 is a straight-shank indexable drill body in the KenTIP FS series, designed for high-productivity drilling in machining centers and CNC turning applications. Built around a KTFS toolholder style, the body accepts indexable drill tip inserts and delivers a 3xD depth-to-diameter ratio. The shank diameter is 1 inch, with through-coolant capability that directs cutting fluid directly to the cutting zone for effective chip evacuation and heat control. This drill body is intended for use by machinists and tooling specialists in production and job-shop environments.

The 6389335 is suited for general-purpose and production drilling in ferrous and non-ferrous materials where indexable tooling is preferred over solid carbide drills. The KenTIP FS platform uses a front-loading, self-centering tip that reduces changeover time at the machine. Applications include drilling in horizontal and vertical machining centers where through-spindle coolant is available. The 3xD reach covers the majority of standard through-hole and blind-hole drilling operations encountered in production machining.

Key Features

• KenTIP FS series KTFS toolholder style for front-loading indexable drill tips
• 3xD drill depth-to-diameter ratio for standard through-hole and blind-hole applications
• 1 inch straight-cylindrical shank for direct spindle or chuck mounting
• Through-coolant capable for improved chip evacuation and tool life
• Flute length of 83.50 mm supports full 3xD drilling depth

Compatibility

Designed as an OEM-style replacement and production component for machining setups using the KENNAMETAL KenTIP FS indexable drill system with KTFS-style toolholders. Specific insert tip compatibility should be confirmed against the KenTIP FS tip selection for the corresponding drill diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable drilling systems. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body. Confirm shank clamping torque and runout per the machine tool and toolholder manufacturer guidelines before cutting. Verify through-coolant passages are clear and coolant pressure is appropriate before initiating the first cut.
