Seco 74024840 Carbide Cutoff Insert 2.49mm Rh Series 150.10

Product Description

The SECO 74024840 is a solid carbide cutoff and parting insert designed for precision grooving and parting-off operations on CNC lathes and turning centers. It belongs to the Series 150.10 product family and features a T25M grade carbide substrate with a CVD-applied TiCN coating for extended tool life in demanding universal material applications. The insert has a cutting width of 2.49mm (0.0980 inches), a corner radius of 0.0070 inches, and an overall length of 0.3540 inches (8.99mm). A right-hand lead angle of 6 degrees and chipbreaker geometry 12 are built into the insert design. Clamping is the designated holding method.

This insert is suited for parting and cutoff applications across a broad range of workpiece materials, classified under universal primary workpiece material code OD. Typical use scenarios include production turning environments where consistent chip control and dimensional accuracy at the cutoff point are required. The single-end configuration means the insert is replaced rather than indexed to a second edge. It fits toolholders and blade systems that accept Series 150.10 inserts with a 2.5 insert seat size. Applications span both light manufacturing and high-volume production turning cells where carbide cutoff tooling is standard.

Key Features

• Solid carbide substrate with T25M grade for wear resistance across universal workpiece materials
• CVD TiCN coating applied for extended cutting life and reduced built-up edge
• 2.49mm cutting width with right-hand, 6-degree lead angle for controlled parting cuts
• Corner radius of 0.0070 inches for defined edge geometry at the cutoff point
• Chipbreaker geometry 12 aids chip evacuation during parting operations
• Clamp-style insert holding for positive, repeatable seating in compatible toolholders

Compatibility

Designed for use with Series 150.10 toolholders and blade bodies that accept a 2.5 insert seat size with clamp-style holding. Consult SECO toolholder documentation to confirm blade and shank compatibility before ordering.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Ensure the insert seat and clamping surfaces are clean and free of chips before seating the insert. Follow the toolholder manufacturer torque and clamping guidelines for the specific blade body in use.
