Ingersoll Cutting Tools 5120079 Replaceable Drill Tip 18mm

Product Description

The INGERSOLL CUTTING TOOLS 5120079 is a replaceable drill tip engineered for high-performance drilling in steel and similar ferrous workpiece materials. This solid carbide insert carries the ISO designation TPA1790R01 IN2505 and is manufactured to ANSI standards. It features a 140-degree drill point angle, a regular helical flute geometry with two flutes, and a TiAlN/TiN PVD coating that extends tool life in demanding cutting environments. Coolant-through capability is built in, allowing coolant delivery directly to the cutting edge for improved chip evacuation and thermal management. Seat size 17 ensures proper seating in compatible TPA-series tool bodies.

This replaceable tip is designed for use in TPA-series indexable drill systems commonly deployed in CNC machining centers and production drilling operations. It is suited for spot drilling, through-hole drilling, and coolant-through drilling applications in steel workpieces classified under ISO material grade P15 to P30. The insert clamp holding method provides secure, repeatable tip location. This tip is a practical solution for shops that require consistent hole quality in steel without the cost of full solid-carbide drills.

Key Features

• Solid carbide construction in manufacturer grade IN2505 for wear resistance in steel cutting
• TiAlN/TiN PVD coating for extended tool life and heat resistance
• 140-degree included angle drill point for accurate entry and reduced thrust in steel
• Two helical flutes with regular spiral for efficient chip evacuation
• Coolant-through design directs cutting fluid to the tip for thermal control
• Clamp-style insert holding for secure, repeatable positioning in TPA-series bodies

Compatibility

Designed for use with TPA-series indexable drill bodies requiring insert seat size 17. Compatible with TPA1790R01-style tool holders. Intended for primary use on steel workpieces (ISO P-class materials, grades P15 to P30).

Installation Notes

This replaceable drill tip is installed and serviced by machinists or toolroom technicians on CNC turning or machining center setups. Ensure the machine spindle is fully stopped and locked out before replacing the tip. Use the correct clamp screw torque as specified by the tool body manufacturer - do not use values not provided with the holder documentation. Verify coolant-through passages are clear and unobstructed before resuming operation.
