Seco 74005316 Carbide Cutoff Insert T25M Series 150.10

Product Description

The SECO 74005316 is a solid carbide cutoff and parting insert designed for grooving and parting operations on CNC lathes and turning centers. Built to Series 150.10 geometry, this single-end insert features a 0.2-inch cutting width, a 0.01-inch corner radius, and a neutral lead angle, making it well suited for straight, consistent cutoff passes. The T25M manufacturer grade insert is produced via CVD coating, applying a multi-layer TiC, TiCN, and TiN finish that supports heat resistance and edge durability across a range of workpiece materials. Clamping is the designated holding method. The overall insert length is 0.354 inches, and the part weighs 0.02 pounds.

This insert is intended for parting and cutoff applications on universal workpiece materials, covering a broad range of metals commonly encountered in production turning. The chipbreaker designation is 12, which is appropriate for controlled chip evacuation during cutoff passes. Installation is performed using compatible Series 150.10 clamp-style toolholders. The insert is rated for use across multiple material types under its OD material grade classification, making it a practical choice for general-purpose turning shops running mixed-material jobs.

Installation Notes

This insert is installed by a machinist or tooling technician using the appropriate clamp and toolholder from the Series 150.10 system. Power down and lock out the machine before seating or replacing the insert. Inspect the insert pocket and clamping screw for wear or debris prior to installation. Follow the toolholder manufacturer torque guidelines for the clamping screw to ensure proper seating without damaging the insert.
