Iscar 5902288 Laydown Threading Insert 60 Degree Solid Carbide

Product Description

The ISCAR 5902288 is a laydown threading insert designed for external thread cutting on a wide range of workpiece materials. Built from solid carbide with a PVD-applied TiAlN coating, this insert handles left-hand external partial profile 60-degree threads across a range of 48 to 16 threads per inch (TPI), covering a metric pitch range of 0.50 to 1.50 millimeters. The insert seats in the laydown orientation and carries the IC908 manufacturer grade, which is suited for demanding threading operations. It belongs to the ISCARTHREAD series and is sized at 3/8 inches inscribed circle with a thickness of 0.143 inches. Licensed machinists and toolroom technicians install this insert in CNC lathes and threading toolholders configured for the 16EL style.

This insert is applied in external threading operations across universal workpiece material groups, including ferrous, nonferrous, stainless, heat-resistant alloys, and hardened materials, corresponding to material codes H, K, M, N, P, and S. The partial profile 60-degree thread form makes it suitable for producing unified and metric thread profiles without requiring a dedicated full-profile insert for each pitch. It is commonly used in production turning environments where a single insert needs to cover a broad TPI range efficiently.

Key Features

• Solid carbide substrate with PVD TiAlN coating for wear resistance across diverse material groups
• IC908 grade suited for both continuous and interrupted external threading cuts
• Left-hand external partial profile 60-degree thread form covering 48 to 16 TPI (0.50 to 1.50 mm pitch)
• 16EL insert style in laydown orientation for positive seating in compatible toolholders
• 3/8 inches inscribed circle with a 0.143-inch thickness and 0.05 mm corner radius
• Compliant with ISO 13399 cutting tool data representation standards

Compatibility

Designed for use in 16EL-style laydown threading toolholders configured for left-hand external threading. Specific toolholder compatibility should be verified against ISCAR ISCARTHREAD series toolholder documentation using the 16EL insert style code.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to secure the insert — do not overtighten by feel alone. Confirm insert hand orientation and toolholder geometry match before initiating a threading pass.
