Ingersoll Cutting Tools 4209876 Replaceable Drill Tip IN2505

Product Description

The INGERSOLL CUTTING TOOLS 4209876 is a replaceable drill tip designed for use with compatible TKA-series modular drilling systems. It features a 0.4213 inch (11.00 mm) cutting diameter and a 140-degree drill point angle suited for accurate entry and reduced thrust. The tip is manufactured from solid carbide with a submicron grain material grade and is coated with TiAlN and TiN via a PVD process, providing wear resistance and heat management during cutting. Coolant-through capability channels cutting fluid directly to the cutting edge for chip evacuation and thermal control. This tip is installed and serviced by machinists and tooling technicians working in production or job-shop environments.

This replaceable drill tip is engineered primarily for drilling and spot drilling in cast iron workpieces, classified under ISO material code K. Its helical flute geometry and regular spiral promote consistent chip flow. The TKA series designation corresponds to insert seat size 10.5, and the tip mounts via a clamp-style insert holding method. Typical applications include through-hole and blind-hole drilling operations on CNC machining centers and drill presses where coolant-through capability is available. The part meets ANSI standards and carries the ISO number TKA1070R01 IN2505.

Key Features

• Solid carbide construction with submicron material grade for extended tool life in abrasive materials
• TiAlN and TiN PVD coating for thermal resistance and reduced edge wear
• 140-degree drill point angle minimizes walking and reduces entry thrust
• Coolant-through design directs fluid to the cutting zone for chip evacuation and heat dissipation
• Helical, regular-spiral, 2-flute geometry supports consistent chip flow in cast iron
• Clamp-style insert holding method for secure, repeatable tip seating

Compatibility

Designed for use with TKA-series modular drill bodies requiring insert seat size 10.5. ISO number TKA1070R01 IN2505 identifies the specific seat and geometry pairing. Verify seat size and series compatibility with the holder body before installation.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before removing or seating the drill tip. Clean the insert seat thoroughly before installing the new tip to ensure proper seating and clamping force. Follow the tool holder manufacturer's clamping procedure and use the specified torx or hex key for the clamp screw - do not overtighten.
