Ingersoll Cutting Tools 5120085 Replaceable Drill Tip 18mm

Product Description

The INGERSOLL CUTTING TOOLS 5120085 is a solid carbide replaceable drill tip designed for high-performance drilling in steel and similar P-grade workpiece materials. Part of the TPA series, it features a 140-degree point angle and a 2-flute helical configuration that promotes chip evacuation and accurate entry. The tip is PVD-coated with TiAlN and TiN layers, providing heat resistance and extended cutting life in demanding production environments. Coolant-through capability allows cutting fluid to be delivered directly to the cutting edge, reducing heat buildup and improving hole finish. This tip is installed by machinists and tooling specialists on CNC drilling platforms using compatible TPA-style drill bodies.

This replaceable drill tip is suited for spot drilling and through-hole drilling operations in steel workpieces across ISO P15 to P30 material grades. It is designed for use in production machining environments where repeatable hole quality and tool life are priorities. The coolant-through design makes it especially effective in deep-hole and high-feed drilling applications where heat management is critical. The clamp-style insert holding method ensures secure seating during high-speed operations. Compatible insert seat size is 18, and the ISO number is TPA1850R01 IN2505.

Key Features

• Solid carbide construction in manufacturer grade IN2505 for wear resistance in steel cutting
• PVD-applied TiAlN and TiN dual coating for heat resistance and extended tool life
• 140-degree point angle with standard point type for accurate drill entry and minimal walking
• Coolant-through design delivers fluid directly to the cutting zone
• 2-flute regular helical spiral promotes efficient chip evacuation
• Clamp-style insert holding method for secure, repeatable tip positioning

Compatibility

Designed for use with TPA-series drill bodies accepting insert seat size 18. ISO number TPA1850R01 IN2505. Conforms to ANSI standards. Primary workpiece material is steel, ISO P-grade (P15 to P30).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body and seat are clean and free of chips or debris before seating the tip, as contamination can cause runout and premature tip failure. Use the correct torque wrench and clamp screw specified by the drill body manufacturer - do not overtighten. Confirm coolant-through passages are clear and coolant pressure is set per machine and application requirements before running the spindle.
