Seco 74016548 Carbide Cutoff Insert T25M 0.25 in

Product Description

The SECO 74016548 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured to grade T25M with a CVD-applied TiC/TiCN/TiN multilayer coating, this insert delivers consistent wear resistance and thermal stability during high-speed cutoff work. It features a 0.25 inch cutting width, a 0.012 inch corner radius, and a neutral lead angle with zero degrees of relief, making it well suited for straight plunge cutoff applications. The insert seats via clamp-style holding and is sized to Series 150.10 toolholders. Installation is performed by machinists and CNC tooling technicians working with precision turning equipment.

This insert is intended for cutoff and parting applications across a broad range of workpiece materials, classified under universal primary workpiece material with material grade C5. The neutral hand and neutral lead angle configuration allow use on standard right-hand and left-hand setups without directional bias. It is a single-end insert, meaning it is indexed or discarded when the cutting edge is worn. Typical installations occur in production turning environments, job shops, and maintenance machining operations where reliable groove width control and edge consistency are required.

Key Features

• Solid carbide substrate, grade T25M, for high hardness and edge retention
• CVD multilayer coating: TiC, TiCN, and TiN for enhanced wear and heat resistance
• 0.25 inch cutting width with a width tolerance of 0.003 inch for consistent groove sizing
• 0.012 inch corner radius reduces stress concentration at the cutting edge
• Neutral lead angle and neutral hand allow straight plunge cutoff without lateral cutting force bias
• Clamp-style holding method ensures secure seating in Series 150.10 compatible toolholders
• Chipbreaker designation 16 suited for chip control in universal workpiece materials

Compatibility

Designed for use with Series 150.10 clamp-style cutoff toolholders accepting a size code 6 insert. This is a single-end insert; it is not reversible. Verify toolholder insert pocket dimensions match the 0.354 inch overall insert length before installation.

Installation Notes

Insert installation and indexing should be performed by qualified machinists or CNC tooling technicians with the machine powered down and the spindle locked. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer to secure the insert without cracking the carbide body. Inspect the insert pocket and clamp for debris or damage before seating a new insert. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for this insert size and grade.
