Kennametal 1726238 Cutoff Insert KC5025 Carbide 4 Mm

Product Description

The KENNAMETAL 1726238 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Built to the A2 series standard, it features a 4 mm cutting width (0.1575 inches) and a 4.68 mm cutting height (0.1843 inches). The insert is coated with TiAlN via a PVD process, which provides thermal resistance and extended tool life under demanding cutting conditions. The CM chipbreaker geometry promotes reliable chip control during cut-off operations. Licensed machinists and CNC operators install these inserts using a clamp-style holding method common to A2-series toolholders.

This insert is suited for cut-off and grooving applications in production turning environments, both in job shops and high-volume manufacturing. The neutral lead angle (0 degrees) and 2-degree relief angle make it appropriate for straight parting cuts in ferrous and non-ferrous materials. The KC5025 grade with PVD TiAlN coating targets steel and cast iron workpieces where wear resistance and edge stability are priorities. Material grades C2 and C6 indicate suitability across a range of general-purpose and finishing turning applications.

Key Features

• 4 mm cutting width (0.1575 inches) for precise parting and grooving
• KC5025 carbide grade with PVD-applied TiAlN coating for wear resistance
• CM chipbreaker geometry for controlled chip evacuation
• Neutral lead angle (0 degrees) for balanced radial cutting forces
• 2-degree relief angle reduces rubbing and extends edge life
• A2 series clamp-style holding method for secure, repeatable seating

Compatibility

Designed for use with A2 series clamp-style cutoff and grooving toolholders that accept an insert seat size of 4. Refer to KENNAMETAL A2 series toolholder documentation to confirm correct insert-to-holder fit before installation.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the machine before seating or removing any insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before installing the insert. Do not exceed the toolholder manufacturer's recommended clamping torque, and inspect the clamp and seat for wear at each insert change.
