Kennametal 4114292 Carbide Cutoff Insert 4.05mm

Product Description

The KENNAMETAL 4114292 is a double-ended carbide cutoff insert engineered for grooving and parting operations on CNC lathes and turning centers. It carries the A4C0405N00CF02 style designation and runs in the KCU25 manufacturer grade, a PVD-applied AlTiN coating designed to extend tool life in steel, stainless, and cast iron applications. The insert features a 4.05mm (0.1594 inch) cutting width, a 2-degree relief angle, and a 0.2mm (0.0079 inch) corner radius with a CF chipbreaker geometry that promotes chip control in continuous turning cuts. Clamp-style holding secures the insert in compatible A4-series toolholders.

This insert is suited for production turning environments where consistent chip evacuation and edge integrity are priorities. The neutral lead angle and neutral hand designation make it adaptable to standard straight cutoff and grooving applications without directional restriction. It is typically installed by CNC machinists and tool-and-die professionals in job shop and high-volume manufacturing settings. The double-end design allows the insert to be flipped to a second cutting edge, reducing per-edge tooling cost in repetitive operations.

Key Features

• Double-ended insert provides two usable cutting edges per insert
• AlTiN coating applied via PVD process for improved heat and wear resistance
• CF chipbreaker geometry promotes controlled chip formation during cutoff operations
• 4.05mm cutting width with 0.2mm corner radius for precise groove geometry
• Neutral lead angle and neutral hand — no directional restriction for straight cutoff use
• Clamp-style insert holding method compatible with A4-series toolholders

Compatibility

Designed for use with A4-series clamp-style cutoff and grooving toolholders that accept insert seat size 4. Consult toolholder documentation to confirm insert pocket dimensions before installation.

Installation Notes

Installation is performed by qualified machinists following standard CNC turning center lockout and toolchange procedures. Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or removing inserts. Use a torque wrench and the toolholder manufacturer-specified clamping screw to secure the insert — do not overtighten by feel alone. Inspect the insert pocket for chips or debris before seating to avoid insert rocking or premature edge failure.
