Kennametal 1952847 Cutoff Insert KC5025 Carbide 3.05mm

Product Description

The KENNAMETAL 1952847 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the form designation A4C0305N00CF02 and is manufactured in the KC5025 grade with a PVD-applied TiAlN coating. The insert delivers a 3.05 mm (0.1201 inch) cutting width, a neutral lead angle, and a 2-degree relief angle. The CF chipbreaker geometry promotes controlled chip formation during cut-off work. Machinists and tool crib personnel working in production turning environments specify this insert for its consistent dimensional accuracy and coating durability.

This insert is suited for cut-off and parting applications in production turning operations. It fits into A4 series clamp-style toolholders and is appropriate for use on ferrous and non-ferrous workpieces where a 3.05 mm parting width is required. The KC5025 grade is positioned for interrupted and continuous cut-off work. Insert seat size 3 toolholders are the correct mating holders for this geometry. Typical environments include job shops and production facilities running CNC or manual turning equipment.

Key Features

• KC5025 carbide grade with PVD TiAlN coating for wear resistance in cut-off applications
• 3.05 mm (0.1201 inch) cutting width with neutral lead angle for straight parting cuts
• CF chipbreaker geometry for controlled chip evacuation
• 2-degree relief angle reduces rubbing on the cut face
• A4 series clamp-style insert holding method for positive seating and repeatable indexing
• Corner radius of 0.0079 inch for edge integrity at the cutting corner

Compatibility

Designed for use in A4 series clamp-style toolholders with an insert seat size of 3, as specified in the Kennametal A4 cutoff toolholder system.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool turret is in a safe position before indexing or replacing the insert. Use the correct torque on the clamp screw per the toolholder manufacturer guidelines and confirm the insert seats fully before resuming cutting operations. Verify the correct insert orientation for neutral lead angle before engaging the workpiece.
