Ingersoll Cutting Tools 5120128 Replaceable Drill Tip

Product Description

The INGERSOLL CUTTING TOOLS 5120128 is a replaceable drill tip designed for use in modular drilling systems that accept TMA-series insert seats. Built from solid carbide with a PVD-applied TiAlN/TiN dual coating, this tip delivers the wear resistance and edge integrity required for productive drilling in stainless steel and other tough materials. It carries Manufacturer Grade IN2505 and Material Grade M15/M35 ratings. The 140-degree point angle suits standard drilling and spot drilling operations. Coolant-through capability channels fluid directly to the cutting zone, supporting chip evacuation and thermal control at the tip. Seat size 12.5 matches the corresponding TMA-body holder.

This tip is intended for CNC machining environments where modular drill systems are used on stainless steel workpieces, including M-group materials per ISO classification. The TMA-series design supports fast tip changes without removing the drill body from the spindle, making it well suited for production shops and job shops running high-mix stainless work. Applications include through-hole drilling and spot drilling where consistent entry geometry and coolant delivery are priorities. It is installed and changed by machinists or tooling technicians on CNC lathes, machining centers, and similar equipment.

Key Features

• Solid carbide substrate with PVD TiAlN/TiN coating for extended tool life in stainless steel
• 140-degree standard point angle for accurate entry and reduced thrust
• Coolant-through design channels fluid directly to the cutting edge
• TMA-series seat size 12.5 for secure clamping in matching modular holders
• 2-flute helical geometry with regular spiral for efficient chip flow
• ANSI-standard ISO designation TMA1270R01 IN2505 for straightforward cross-referencing

Compatibility

Designed for use with TMA-series modular drill bodies accepting seat size 12.5. Optimized for primary workpiece material group M (stainless steel) per ISO material classification.

Installation Notes

Replaceable drill tips of this type are installed and torqued using the tool manufacturer's specified clamp screw and driver - verify the correct key and seating procedure against the holder documentation before assembly. Ensure the seat and clamping surfaces are clean and free of chips before inserting the tip. Confirm coolant-through passages in the holder are clear and that system pressure is appropriate for the tip diameter. Always power down and lock out the spindle before changing inserts.
