Seco 02696774 Cutoff Insert Carbide 3.1mm Parting

Product Description

The SECO 02696774 is a solid carbide cutoff insert designed for parting and part-off operations on CNC lathes and turning centers. Built to the Part-Off series specification, it features a 3.1 mm (0.122 inch) cutting width, a 6-degree neutral lead angle, and an uncoated bright finish in manufacturer grade HX. The insert seats via a clamp-style holding method and is rated for universal primary workpiece material, making it suitable across a broad range of ferrous and non-ferrous stock. At 0.354 inch overall length, it is a compact, single-end insert intended as a direct replacement in compatible SECO parting toolholders. Installation requires no special surface prep beyond standard insert-seat cleaning.

This insert is used in parting and grooving applications on manual and CNC turning equipment in both production-shop and job-shop environments. The neutral hand and neutral lead angle orientation make it a straightforward fit for standard radial part-off operations. The HX grade solid carbide construction with an uncoated bright finish performs well on a wide variety of workpiece materials, including general steels, stainless, aluminum, and non-ferrous alloys, consistent with the universal material classification and C2 material grade designation. Machinists and toolroom technicians are the primary installers.
