Seco 02743128 CP500 Carbide Cutoff Insert 3.10mm

Product Description

The SECO 02743128 is a solid carbide cutoff and parting insert in the 150.10 series, designed for precise grooving and parting-off operations on CNC lathes and turning centers. Manufactured to CP500 grade from micrograin solid carbide with a PVD-applied TiAlN/TiN finish, this insert delivers consistent edge integrity at elevated cutting speeds. The neutral lead angle with a 6-degree geometry suits a broad range of workpiece materials. Cutting width measures 3.10mm (0.1220 inches), overall length is 0.354 inches (8.99mm), and the corner radius is 0.008 inches. Installation is accomplished via clamp-style insert holding. Sold as a single insert with a minimum order quantity of 10.

The 02743128 is suited for parting and cutoff applications across universal workpiece materials, including steel, stainless, aluminum, and cast iron, as indicated by the OD material code designation. It is a single-end insert intended for production turning environments where repeatable groove width and tool life predictability are critical. The Series 150.10 platform is a standard clamp-type parting system commonly found on production turning cells in both job shop and high-volume manufacturing settings. Machinists and CNC lathe operators handling repetitive cutoff cycles will find this insert a direct-fit replacement for worn tooling in compatible 150.10 toolholders.

Installation Notes

Installation and replacement of carbide parting inserts should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, de-energized state and spindle locked. Use the appropriate torx or hex key to release the clamp, seat the insert fully against the pocket locating surfaces, and re-torque the clamp fastener per the toolholder manufacturer specification. Inspect the insert seat for chips or debris before seating a new insert, as contamination will affect edge runout and parting accuracy.
