Ingersoll Cutting Tools 4208145 Replaceable Drill Tip 26mm

Product Description

The INGERSOLL CUTTING TOOLS 4208145 is a replaceable drill tip designed for indexable drilling systems used in metal cutting applications. Built from solid carbide and coated with a PVD-applied TiAlN/TiN finish, this insert delivers heat resistance and edge durability during high-speed steel drilling operations. It features a 140-degree drill point angle, two helical flutes, and a regular spiral geometry. The tip includes coolant-through capability, which channels cutting fluid directly to the cutting zone to reduce heat buildup and extend tool life. It is held in place by a clamp mechanism and fits an insert seat size 25. Licensed machinists and CNC operators working in ferrous metal cutting applications will find this tip a direct-fit insert for compatible TPA-series bodies.

This replaceable tip is intended for use in TPA-series indexable drill bodies on CNC machining centers and drilling stations. It is suited for spot drilling and through-hole drilling in steel workpieces classified under ISO material group P, covering low to medium carbon steels and alloy steels within P15 to P30 material grades. The coolant-through design makes it particularly effective in deep-hole drilling scenarios where chip evacuation and thermal management are critical. Applications include production drilling, general-purpose steel boring, and spot drilling operations requiring a standard point geometry.

Key Features

• Solid carbide construction with PVD-applied TiAlN/TiN coating for extended wear resistance
• 140-degree included point angle for standard drilling and spot drilling in steel
• Coolant-through design channels fluid directly to the cutting edge for thermal control and chip clearance
• Two helical flutes with regular spiral geometry for efficient chip evacuation
• Insert seat size 25 with clamp-style holding for secure, repeatable positioning
• Meets ANSI standards; ISO number TPA2570R01 IN2505

Compatibility

Designed for use with TPA-series indexable drill bodies requiring an insert seat size 25. Intended for primary workpiece materials classified as ISO P-group steels, including P15 and P30 material grades.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before seating or removing the insert. Verify the insert pocket and seating surface are clean and free of chips before clamping. Consult the drill body manufacturer torque guidance for the clamping screw and confirm coolant passages are clear before resuming operation.
