Kennametal 6371979 Kentip Fs Indexable Drill Body

Product Description

The KENNAMETAL 6371979 is a KenTIP FS series indexable drill body with a straight cylindrical shank, designed for high-performance drilling in machining centers and CNC turning applications. The body accepts interchangeable KenTIP FS drill tip inserts, allowing fast tip changes without removing the tool from the spindle. Key dimensional specs include a 14 mm shank diameter, 132 mm overall length, and 82.40 mm flute length. The 5xD depth-to-diameter ratio makes this body suited for deeper hole applications where a single-pass strategy is required. Coolant-through capability is built in to support chip evacuation and tool life at elevated cutting speeds. This tool body is installed and serviced by machinists and CNC toolroom technicians.

The 6371979 drill body fits production environments running ferrous and non-ferrous materials where modular indexable drilling systems are preferred over solid carbide or brazed tooling. The KTFS toolholder style is specific to the KenTIP FS platform. With a 46 mm shank length and straight cylindrical interface, it seats in standard ER collet chucks, hydraulic chucks, and shrink-fit holders sized for 14 mm shanks. Typical applications include batch hole-making operations on machining centers in automotive, aerospace, and general metalworking shops.

Key Features

• KenTIP FS modular platform allows tip-only replacement without full tool changeout
• 5xD drill depth ratio supports deeper holes in a single pass
• Coolant-through design aids chip evacuation and reduces heat at the cutting edge
• Straight cylindrical shank compatible with standard 14 mm toolholding systems
• KTFS toolholder style for direct compatibility with KenTIP FS insert tips
• Compact 132 mm overall length suits space-constrained spindle setups

Compatibility

Designed for use with KenTIP FS series interchangeable drill tip inserts using the KTFS toolholder interface. Specific compatible tip part numbers were not provided in available product data; consult KENNAMETAL documentation to match the correct KenTIP FS tip for the desired drill diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician familiar with indexable tooling systems. Ensure the machine spindle is fully stopped and the tool change mode is engaged before mounting or tip replacement. Seat the shank fully into the holder and confirm the retention mechanism is properly torqued per the toolholder manufacturer specification before cutting. Verify coolant-through passages are clear and aligned with the machine coolant supply before running at operating pressure.
