Seco 74024843 Carbide Cutoff Insert T25M 0.122in

Product Description

The SECO 74024843 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the T25M manufacturer grade and is finished with a CVD-applied TiC/TiCN/TiN multilayer coating that improves wear resistance and tool life. The insert features a 0.122 inch cutting width, a 0.008 inch corner radius, and a 6-degree right-hand lead angle. It is held in place by a clamp-style toolholder and is suited for universal workpiece materials across a wide range of turning applications. Installation and toolholder selection require a licensed machinist or qualified CNC operator.

This insert fits within the Series 150.10 cutoff and grooving system and is intended for single-end use. It is sized with an insert size code of 3 and carries a material grade of C5, making it appropriate for general-purpose OD turning and cutoff work on a broad range of metals. The chipbreaker designation is 12. No multi-use or double-end configuration applies to this part. Typical applications include production parting, groove forming, and cutoff operations on bar-fed or chucked turning setups in both job-shop and production environments.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Use the correct clamp and toolholder specified for Series 150.10 size code 3 inserts. Inspect the insert pocket and clamp for debris or wear before seating the new insert to ensure proper clamping force and insert stability.
