Kennametal 6370958 Replaceable Drill Tip 14mm KC7410

Product Description

The KENNAMETAL 6370958 is a replaceable drill tip in the KTFST series, designed for use with compatible modular drill bodies in high-performance cutting applications. The tip measures 14.00 mm (0.5512 inches) in cutting diameter and features a 140-degree drill point angle optimized for fast penetration and chip evacuation. Manufactured from solid carbide with a PVD-applied AlCr coating and KC7410 grade, it delivers wear resistance and thermal stability in demanding cutting conditions. The HPC insert geometry and helical flute design support aggressive feed rates. Coolant-through capability directs fluid directly to the cutting edge for improved tool life and chip flushing.

This drill tip is engineered primarily for drilling cast iron (ISO material group K, grade K15). Typical applications include straight drilling, inclined exit drilling, cross-hole drilling, and stacked-plate drilling. The two-flute, four-margin configuration with regular spiral and clamp-style insert holding makes it well suited for production machining environments where consistent hole quality and tool change efficiency are priorities. The insert seat size is R, matching compatible KTFST-series drill bodies.

Key Features

• Solid carbide construction with PVD AlCr coating for thermal and wear resistance
• 140-degree point angle for reduced thrust and efficient chip formation
• Coolant-through design channels fluid directly to the cutting zone
• HPC insert geometry supports high-performance cutting in cast iron
• Two-flute, four-margin helical flute design for accurate hole geometry
• Clamp-style holding method for secure, repeatable tip seating

Compatibility

Designed as an OEM-style replaceable tip for KTFST-series modular drill bodies requiring an R-seat insert. ISO number KTFST14000HPCM. Verify seat size and series compatibility with the drill body before installation.

Installation Notes

Replaceable drill tips of this type are installed and serviced by machinists or tooling technicians on CNC machining centers and drill presses. Power down and lock out the spindle before tip replacement. Ensure the insert seat is clean and free of chips or debris before seating the tip, as contamination can affect runout and tool life. Follow the drill body manufacturer's clamping torque specifications for the KTFST seat interface.
