Ingersoll Cutting Tools 5120075 Indexable Drill Insert TPA17

Product Description

The INGERSOLL CUTTING TOOLS 5120075 is a solid carbide indexable drill insert designed for precision drilling in steel workpieces. Manufactured to the TPA series specification with a size 17 insert seat, this insert carries grade IN2505 with a micro grain carbide substrate and a PVD-applied TiAlN/TiN coating for thermal and wear resistance. It features a standard 140-degree point angle and a P-geometry insert profile with two flutes, making it well suited for productive metal removal in demanding drilling applications. The insert is held by a twist locking method and supports coolant-through delivery for chip evacuation and heat control at the cutting zone.

This insert is intended for use in indexable drill bodies that accept TPA series, size 17 inserts. The ISO designation TPA1750R01 IN2505 identifies the exact insert geometry and grade. Primary workpiece material is steel, classified under ISO material group P. Typical application is production drilling in CNC machining centers and turning centers where consistent hole quality and insert life in ferrous materials are required. The coolant-through capability makes it compatible with spindle-delivered coolant systems commonly found in production shop environments.

Key Features

• Solid micro grain carbide substrate with PVD-applied TiAlN and TiN coating for extended tool life in steel
• 140-degree standard point angle for self-centering entry and reduced thrust force
• Coolant-through design channels fluid directly to the cutting edge for heat control and chip evacuation
• P-geometry insert profile optimized for steel ISO group P workpiece materials
• Twist insert holding method for positive seating and repeatable positioning in compatible drill bodies
• Two-flute configuration supports balanced cutting forces during drilling

Compatibility

Designed for use in indexable drill bodies accepting TPA series size 17 inserts. ISO designation TPA1750R01 IN2505 identifies the insert for direct cross-reference with compatible tooling systems.

Installation Notes

Installation of indexable drill inserts should be performed by a qualified machinist or tooling technician. Ensure the drill body insert pocket is clean and free of chips or debris before seating the insert. Use the manufacturer-recommended torx or hex key to secure the insert to the specified clamp torque for the drill body model in use. Never exceed recommended cutting parameters for the grade and coating specified.
