Ingersoll Cutting Tools 5901569 Threading Insert 18 Tpi

Product Description

The INGERSOLL CUTTING TOOLS 5901569 is a laydown threading insert designed for external thread milling on CNC lathes and turning centers. Manufactured from solid carbide in the TT9030 grade, this insert features a PVD-applied TiAlN coating that provides heat resistance and extended tool life when cutting stainless steel and similarly demanding workpiece materials. It produces UN 60-degree external threads at 18 threads per inch and follows the 16ER series geometry. The right-hand cutting orientation and 0.006-inch corner radius make it a dependable choice for machinists and toolroom professionals who need consistent thread form accuracy in production environments.

This insert is suited for external threading operations in precision machining environments including job shops, production floors, and contract manufacturing facilities. It is specifically optimized for stainless steel workpieces and is compatible with 16ER series toolholders that accept ER-style laydown inserts. The UN 60-degree thread standard makes it applicable to common unified national thread forms encountered across industrial, automotive, and aerospace component work.

Key Features

• Carbide substrate in manufacturer grade TT9030 for wear resistance in difficult-to-machine materials
• PVD TiAlN coating for thermal protection and extended cutting life
• UN 60-degree thread form at 18 TPI for unified national external threads
• Right-hand cutting orientation with a 0.006-inch corner radius for accurate thread profile
• 16ER series ER-style laydown geometry for compatibility with standard toolholder systems
• Optimized for stainless steel primary workpiece material

Compatibility

Designed for use with 16ER series toolholders that accept ER-style laydown threading inserts. Fits standard insert pockets in that series.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torx or clamping screw driver specified by the toolholder manufacturer to secure the insert without over-torquing the clamping mechanism. Verify thread form and pitch with a thread gauge on the first part before committing to a production run.
