Seco 74016518 Cutoff Insert 0.122 in Carbide T25M Cvd

Product Description

The SECO 74016518 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It belongs to the Series 150.10 platform and is held in place by a clamp-style toolholder. The insert features a 0.122-inch cutting width, a right-hand lead angle of 6 degrees, and a CVD-applied TiC/TiCN/TiN multilayer coating classified under material grade C5. The T25M grade is engineered for universal workpiece materials, making it suitable across a broad range of turning applications. Machinists and toolroom technicians install this insert as part of a dedicated cutoff tooling system.

This insert is suited for cut-off operations in both production and job-shop turning environments. The right-hand configuration fits standard right-hand Series 150.10 toolholders. The single-end design means the insert is indexed or replaced rather than flipped. The 0.122-inch cutting width and 6-degree lead angle are common selections for moderate-diameter bar stock parting. The universal primary workpiece material rating covers steel, stainless, cast iron, and non-ferrous alloys, giving tooling engineers flexibility when setting up new jobs.

Key Features

• CVD-deposited TiC/TiCN/TiN multilayer coating for heat and wear resistance
• T25M carbide grade rated for universal primary workpiece materials
• 6-degree right-hand lead angle for directional chip control
• Clamp-style insert holding method for secure seating in Series 150.10 toolholders
• Single-end insert with chipbreaker designation 16

Compatibility

Designed for use with Series 150.10 clamp-style cutoff toolholders configured for right-hand, single-end carbide inserts.

Installation Notes

Installation is performed by a machinist or toolroom technician. The machine spindle must be stopped and the toolholder fully secured in the turret before seating or replacing the insert. Use the correct clamping screw torque specified by the toolholder manufacturer — no torque value is provided with this insert. Inspect the insert pocket and clamp for chips or debris before seating to ensure proper contact and avoid premature edge failure.
