Seco 00045794 Laydown Threading Insert CP500 Solid Carbide

Product Description

The SECO 00045794 is a laydown threading insert designed for internal ISO threading operations. Built from solid carbide with a micrograin substrate and a PVD-applied TiAlN/TiN coating, this insert delivers consistent thread quality across a wide range of workpiece materials. It carries the CP500 manufacturer grade and is engineered for the Snap Tap series. The insert measures 0.2500 inches inscribed circle diameter and 0.1181 inches thick. The included angle is 60 degrees, matching the ISO thread form. Right-hand orientation and a 1.5 mm pitch make it a direct-fit for standard ISO internal threading applications in production and maintenance environments. Licensed machinists and CNC operators are the primary users.

This insert is suited for internal threading on CNC lathes and turning centers handling materials spanning steel, stainless, aluminum, and heat-resistant alloys. The Universal primary workpiece material classification, with material grade codes K, M, N, P, and S, means this insert covers a broad range of metals without requiring a grade change between jobs. Typical use cases include threading bores on hydraulic fittings, valve bodies, and precision machined components where ISO thread standards are specified.

Key Features

• Solid carbide micrograin substrate for wear resistance and edge stability
• PVD TiAlN/TiN coating reduces heat buildup and extends tool life
• 1.5 mm ISO pitch, 60-degree included angle for standard ISO internal thread form
• Right-hand cut, laydown style seating for secure insert positioning
• Universal material grade coverage: K, M, N, P, and S workpiece codes
• 0.0050 inch corner radius for precise thread root geometry

Compatibility

Designed for use in toolholders accepting the 11NR insert style within the SECO Snap Tap series for right-hand internal ISO threading.

Installation Notes

Threading inserts of this type are seated and torqued into compatible Snap Tap toolholders by qualified machinists following machine shop procedures. Always disengage spindle power and confirm zero spindle speed before indexing or replacing inserts. Use the appropriate insert torx or hex key as specified by the toolholder manufacturer — do not overtighten, as solid carbide inserts are brittle and susceptible to fracture under excess clamping force. Verify thread pitch and insert orientation before resuming cutting operations.
