Kennametal 7002472 Replaceable Drill Tip 25mm KC7325

Product Description

The KENNAMETAL 7002472 is a replaceable drill tip designed for indexable drill systems where the cutting head is replaced independently of the drill body. This tip measures 0.9843 inches (25.00 mm) in cutting diameter and features a 140-degree point angle with a standard point type and regular helical spiral flute geometry. Manufactured from fine-grain solid carbide in the KC7325 grade and coated with a PVD-applied TiAlN/TiN multilayer finish, it delivers wear resistance and thermal stability in demanding drilling applications. Coolant-through capability is built in, supporting high-feed rates and effective chip evacuation during deep-hole drilling operations.

This tip is suited for use in production drilling environments across both general metalworking and precision machining shops. It targets ferrous and exotic workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. Typical install scenarios include CNC machining centers performing through-hole and blind-hole drilling on flat, inclined, or stacked-plate workpiece configurations. The GTP insert geometry and ZD seat size are specific to the KTFST series drill body platform. Machinists and tooling setters working in high-mix or high-volume environments will find the replaceable-tip format reduces downtime compared to full drill replacement.

Key Features

• Fine-grain solid carbide construction in KC7325 grade for hardness and edge retention
• PVD-applied TiAlN/TiN coating for oxidation resistance and reduced friction at the cutting edge
• 140-degree point angle for self-centering entry and reduced thrust force
• Coolant-through design channels fluid directly to the cutting zone for thermal control and chip flushing
• 2-flute, 2-margin helical geometry compatible with inclined exit and stacked-plate drilling applications
• Indexable replaceable-tip format reduces tooling cost and changeover time versus disposable full drills

Compatibility

Designed for use with KTFST series indexable drill bodies requiring a ZD insert seat size and GTP insert geometry. ISO designation for this tip is KTFST25000GTPM.

Installation Notes

Tip installation and replacement should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Use the correct clamp torque driver specified by the drill body manufacturer for the ZD seat interface — do not substitute. Verify coolant-through passages are clear and unobstructed before resuming operation. Inspect the drill body seat for wear or damage each time the tip is replaced to maintain runout tolerances.
