Seco 00050436 Laydown Threading Insert 16NR 1.75ISO-G1

Product Description

The SECO 00050436 is a laydown threading insert designed for external thread cutting operations on CNC lathes and manual turning centers. Designated in the 16NR geometry with a 1.75ISO-G1 thread profile, this insert is manufactured from SECO CP500 carbide grade, a coated carbide substrate suited for threading a range of materials including steel and stainless steel. It is used by machinists and toolroom professionals who require consistent thread form accuracy across production runs. The insert mounts in a standard laydown-style threading toolholder and is sold individually.

This insert is appropriate for external ISO metric threading applications where a 1.75 mm pitch profile is required. The CP500 grade provides wear resistance suitable for moderate to high cutting speeds in ferrous materials. Typical installations are found in job shops, production machining environments, and maintenance machining operations where metric fastener threads are cut to specification. The insert is packaged as a single unit, making it practical for low-volume tooling replenishment or trial use.
