Ingersoll Cutting Tools 4207959 Replaceable Drill Tip

Product Description

The INGERSOLL CUTTING TOOLS 4207959 is a replaceable drill tip designed for indexable drilling systems used in metal cutting applications. Built from solid carbide with a PVD-applied TiAlN and TiN coating, this tip delivers wear resistance and heat management during high-feed drilling operations. It measures 25.00 mm (0.9843 inches) in cutting diameter with a 140-degree point angle and a helical, 2-flute geometry. The tip uses a clamp-style insert holding method and is coolant-through capable, supporting internal coolant delivery for chip evacuation and thermal control. It is installed by machinists and toolroom technicians in CNC turning and machining centers.

This replaceable tip is suited for drilling and spot drilling in steel workpieces, corresponding to ISO material group P (grades P15 through P30). It belongs to the TPA series and carries an insert seat size of 25, making it compatible with TPA-series drill bodies of the matching seat size. Typical applications include production drilling in ferrous materials where coolant-through capability and consistent point geometry are required for hole quality and tool life.

Key Features

• Solid carbide construction for rigidity and wear resistance in steel cutting
• TiAlN and TiN PVD coating for thermal protection and extended tool life
• 140-degree point angle with standard point type for accurate entry and reduced thrust
• Helical, 2-flute geometry promotes efficient chip evacuation
• Coolant-through design supports internal coolant delivery directly to the cutting edge
• Clamp-style insert holding ensures secure seating in compatible TPA drill bodies

Compatibility

Designed for use with TPA-series indexable drill bodies requiring an insert seat size of 25. ISO number TPA2500R01 IN2505. Verify seat size and series designation against the drill body specification before ordering.

Installation Notes

This tip is installed and replaced by machinists or toolroom personnel during scheduled insert changes on CNC machining centers. Power down and lock out the spindle before seating or removing the insert. Use the correct torque tool for the clamp screw as specified by the drill body manufacturer - do not overtighten or use improvised tools. Confirm coolant-through passages are clear and aligned before resuming operation.
