Ingersoll Cutting Tools 5120145 Replaceable Drill Tip

Product Description

The INGERSOLL CUTTING TOOLS 5120145 is a replaceable drill tip designed for use with modular indexable drill systems. Built from solid carbide in the IN2505 micro grain grade, this tip delivers consistent cutting performance across a wide range of workpiece materials. It features a 140-degree point angle optimized for self-centering and reduced thrust in general-purpose drilling operations. A PVD-applied TiAlN and TiN coating enhances wear resistance and extends tool life in demanding machining environments. Licensed machinists and CNC tooling technicians are the primary installers of this tip style.

The 5120145 tip belongs to the TMA series and is sized for a 14mm insert seat. With a cutting diameter of 14.40mm and a functional length of 0.2350 inches, it is suited for precision through-hole and blind-hole drilling in ferrous metals, cast iron, non-ferrous alloys, high-temperature alloys, and hardened materials. Coolant-through capability supports chip evacuation and thermal control during high-feed drilling cycles, making it appropriate for both production and job-shop environments.

Key Features

• Solid carbide IN2505 micro grain substrate for wear resistance and edge integrity
• 140-degree point angle for self-centering entry and reduced axial thrust
• PVD-applied TiAlN and TiN dual coating for thermal and abrasion resistance
• Coolant-through design aids chip flushing and heat management
• 2-flute geometry with M-style insert geometry for universal material compatibility
• ISO designation TMA1440R01 for cross-reference and system matching

Compatibility

Designed for use in TMA series modular indexable drill bodies with a 14mm insert seat. Primary workpiece material compatibility codes are P, M, K, S, and H, covering steel, stainless, cast iron, superalloys, and hardened materials. ISO number TMA1440R01 applies.

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine locked out. The tip seat and clamping surfaces should be clean and free of chips or debris before seating the insert. Use the correct torque tool or wrench specified by the drill body manufacturer - do not overtighten or use improvised tools. Verify runout and tip seating with a dial indicator before returning the tool to service.
