Kennametal 7004225 Replaceable Drill Tip 17.5mm Solid Carbide

Product Description

The KENNAMETAL 7004225 is a replaceable drill tip designed for use with modular drill bodies in the KTFST series. Manufactured from solid carbide with a fine grain material grade (KC7325), this tip features a PVD-applied dual coating of TiAlN and TiN for extended tool life in demanding cutting environments. The 140-degree included angle suits standard drilling applications, and the through-coolant design delivers cutting fluid directly to the tip for heat management and chip evacuation. Installation is via clamp-style insert holding into a size V seat. The two-flute, regular helical spiral geometry supports consistent chip flow and accurate hole entry.

This replaceable tip is suited for drilling operations in steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material codes P, M, K, and S. Typical applications include standard through-hole drilling, inclined surface entry, and stacked plate drilling. The KTFST series design allows the tip to be swapped at the machine without removing the drill body from the spindle, reducing changeover time in production environments. It is used in CNC machining centers and turning centers by machinists and tooling technicians.

Key Features

• Solid carbide construction with fine grain material grade KC7325 for wear resistance
• PVD-applied TiAlN and TiN dual coating for heat and abrasion resistance
• Through-coolant capability for effective chip evacuation and tip cooling
• 140-degree drill point angle for standard drilling geometry
• Two-flute helical design supports inclined entry and stacked plate drilling
• Clamp-style holding into size V seat for secure, repeatable tip indexing

Compatibility

Designed as a replaceable tip for KTFST series modular drill bodies using an insert seat size V. ISO number for this tip is KTFST17500GTPM. 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 qualified machinists or tooling technicians. Power down and lock out the machine spindle before removing or installing any insert tip. Use the appropriate torx or clamp key as specified by the tool body manufacturer for the KTFST seat — do not over-torque the clamping mechanism. Inspect the insert seat for debris or damage before seating the new tip to ensure accurate tip location and secure retention.
