Iscar 5995010 Laydown Threading Insert 8 Tpi Acme IC908

Product Description

The ISCAR 5995010 is a laydown threading insert engineered for external ACME thread profiles at 8 threads per inch. Manufactured from solid carbide with an IC908 grade designation, this insert is designed for right-hand threading operations on CNC and manual lathes. The IC908 grade is suited for a broad range of workpiece materials, making it a versatile choice for shops running mixed-material production. Insert style is 16ER, a widely used laydown geometry that seats securely in compatible toolholders and delivers consistent thread form across production runs.

This insert is used in external threading applications where ACME thread profiles are required, such as lead screws, power transmission components, and jack screw assemblies. It is appropriate for both light production and job-shop environments. Compatible workpiece material codes include H, K, M, N, P, and S, covering carbon steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys. Machinists and toolroom operators working in general manufacturing, aerospace component work, and industrial equipment repair will find this insert applicable across common threading scenarios.

Key Features

• IC908 carbide grade for broad workpiece material compatibility across H, K, M, N, P, and S classifications
• 16ER insert style with right-hand cutting geometry for external threading
• ACME thread profile at 8 threads per inch for power transmission and lead screw applications
• Solid carbide construction for dimensional stability and edge retention under interrupted or continuous cuts
• Conforms to ISO 13399 standards for tooling data representation and toolholder interoperability

Compatibility

Designed for use in 16ER-style laydown threading toolholders compatible with the ISCARTHREAD series. Suitable for external ACME threading operations on workpiece materials classified under ISO codes H, K, M, N, P, and S.

Installation Notes

Installation is performed by qualified machinists following standard CNC or manual lathe toolchange procedures. Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or removing inserts. Use the appropriate torx or clamping screw driver specified for the toolholder to achieve proper insert clamping without over-torquing. Verify insert seating and thread profile with a thread gauge before running production parts.
