Description

The SECO 00049893 is a laydown threading insert designed for external ISO thread-cutting operations on CNC lathes and turning centers. Built from solid carbide with a PVD-applied TiAlN/TiN coating, it operates under the CP500 manufacturer grade and targets demanding threading work in cast iron, stainless steel, and carbon steel. The insert produces a 60-degree included angle at a 2.0mm pitch, conforming to the ISO thread standard. With a 9.53mm inscribed circle and a thickness of 3.47mm (0.1366 inches), the 00049893 fits toolholders designed for the 16ER insert style. The A1 chipbreaker geometry supports chip control during single-point threading passes.

This insert is suited for precision threading in industrial machining environments, including job shops, production turning, and maintenance-repair operations. It is used in right-hand external threading applications where ISO metric thread profiles are required. Target workpiece materials include cast iron (K), stainless steel (M), and steel (P), covering a wide range of common production and repair scenarios. The Snap Tap series designation indicates compatibility with toolholder systems engineered for that insert family.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket and torque the clamping screw per the toolholder manufacturer specification. Inspect the insert seat and clamp for wear or debris before each insert change to ensure accurate thread-form geometry.
