Iscar 5902780 Threading Insert 60 Deg 48-16 Tpi IC908

Product Description

The ISCAR 5902780 is a laydown threading insert designed for external thread cutting on CNC lathes and turning centers. Manufactured from solid carbide with an IC908 grade and a PVD-applied TiN/TiAlN coating, this insert delivers wear resistance and edge stability across a broad range of workpiece materials. It cuts a partial profile 60-degree thread form with a right-hand orientation, covering a threads-per-inch range of 48 to 16 TPI and an equivalent metric pitch range of 0.50 to 1.50 mm. The inscribed circle measures 3/8 inch (9.53 mm) and the insert thickness is 0.143 inches. It is part of the ISCARTHREAD series and conforms to ISO 13399 standards.

This insert is suited for external threading operations in general-purpose and precision turning applications across residential, commercial, and industrial machining environments. The universal primary workpiece material designation covers steel, stainless steel, cast iron, non-ferrous alloys, and high-temperature alloys, making it a versatile choice for shops running mixed-material production. The 16ERB insert style mounts in compatible laydown threading toolholders. Installation is performed by machining professionals and CNC setup technicians.

Key Features

• IC908 carbide grade with PVD TiN/TiAlN coating for extended tool life and thermal resistance
• Partial profile 60-degree thread form covers both unified and metric thread standards
• Right-hand external threading orientation, 48 to 16 TPI range
• Chipbreaker style B for controlled chip evacuation during threading passes
• ISO 13399 compliant insert geometry for standardized tooling data integration
• Universal material compatibility: steel, stainless, cast iron, non-ferrous, and superalloys

Compatibility

Designed as an OEM-style replacement for laydown external threading applications requiring a 16ERB insert style in IC908 carbide grade. Fits compatible laydown threading toolholders accepting the 16ERB form factor.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and de-energize the machine tool before changing inserts. Use the correct torx or clamping screw driver specified for the toolholder system to seat the insert fully and evenly. Do not use damaged or improperly seated inserts, as this can cause premature failure or workpiece damage.
