Vargus 51962 Laydown Threading Insert Iso External Carbide

Product Description

The VARGUS 51962 is a solid carbide laydown threading insert designed for external ISO thread cutting on CNC lathes and turning centers. Manufactured in the 3JER insert style with a 60-degree included angle, this insert targets 1.5mm pitch ISO threads and carries a TiN coating applied by PVD process for improved surface hardness and tool life. The insert measures 9.53mm inscribed circle (3/8 inch) and 3.60mm thick, making it a compact, right-hand cutting tool suited for precision threading operations in production and job-shop environments. Machinists and CNC operators working with ISO-standard external thread profiles install and index this insert as a direct replacement in compatible toolholders.

This insert is suited for external threading passes on turned components where 1.5mm pitch ISO profiles are required. Typical applications include threading steel and ferrous alloy workpieces on CNC turning equipment. The single-tooth-per-side geometry delivers a clean, controlled thread form. Right-hand cutting orientation makes it appropriate for standard forward-turning thread cycles. The TiN finish helps resist built-up edge and extends interval between insert indexes in moderate-speed threading operations.

Key Features

• Single tooth per side for precise thread profile control

Compatibility

Designed as an OEM-style replacement threading insert for 3JER-style toolholders accepting a 9.53mm inscribed circle laydown insert with ISO external thread geometry.

Installation Notes

A qualified CNC machinist or toolroom technician should install this insert. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the pocket and torque the clamping screw to the toolholder manufacturer's specification. Inspect the insert seat and clamping components for wear or debris before each installation to ensure accurate thread form.
