Seco 74016601 Carbide Cutoff Insert T25M Series 150.10

Product Description

The SECO 74016601 is a solid carbide cutoff insert designed for parting and grooving operations on CNC turning centers and lathes. Manufactured to the T25M grade with a CVD-applied TiC/TiCN/TiN multilayer coating, this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. It carries a 0.161 inch cutting width, a 0.009 inch corner radius, and a neutral lead angle with zero relief angle. The insert seats via clamp-style holding and is classified within the Series 150.10 tooling system. Machinists and CNC setup technicians working in production turning environments will find this insert suited to consistent, repeatable cutoff work.

This insert is intended for cutoff and parting applications in both light and medium-duty turning operations. The universal primary workpiece material rating indicates suitability across a broad range of metals and alloys. The chipbreaker designation 16 is specific to the Series 150.10 insert geometry system. This is a single-end insert. It is sold individually but carries a minimum order quantity of 10 pieces, making it appropriate for shop stock replenishment or tooling room inventory at production facilities.

Compatibility

Designed for use with Series 150.10 clamp-style cutoff toolholders that accept inserts with a size code of 4 and a 0.161 inch cutting width. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Installation of indexable carbide cutoff inserts should be performed by a qualified machinist or CNC tooling technician with the machine powered off and locked out per facility LOTO procedures. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before seating the insert. Torque the clamp fastener according to the toolholder manufacturer specifications — do not substitute generic values. Inspect the insert for chipping or coating damage before each use and replace at the first sign of edge breakdown to avoid workpiece damage or toolholder wear.
