Kennametal 5941074 Cutoff Insert KCU25 Carbide 3 Mm

Product Description

The KENNAMETAL 5941074 is a carbide cutoff insert from the Beyond Evolution series, designed for parting and grooving operations on CNC lathes and turning centers. It features a 3.00 mm (0.1181 inch) cutting width with a neutral, left-hand orientation and a 0-degree lead angle, making it well suited for straight cutoff work with minimal lateral cutting forces. The AlTiN coating is applied via PVD process, providing wear resistance and thermal stability during high-speed interrupted cuts. Machinists and tool-and-die technicians working in production turning environments are the primary installers and users of this insert.

This insert is built for cut-off and parting applications in production machining environments. Its EC-U insert style and CF chipbreaker geometry support controlled chip evacuation in ductile materials. The single-end design and insert seat size 3 make it a direct fit for compatible Beyond Evolution toolholders. It is appropriate for use in both light-duty and moderate-duty turning operations where consistent part-off quality and dimensional repeatability are required.

Key Features

• Carbide substrate with AlTiN PVD coating for extended wear life in high-speed cutoff operations
• 3.00 mm (0.1181 inch) cutting width for precise parting groove dimensions
• CF chipbreaker geometry promotes controlled chip formation and evacuation
• 0-degree lead angle with left-hand, neutral orientation for straight cutoff entry
• 2-degree relief angle and 0.0080 inch corner radius for clean edge engagement
• Beyond Evolution series insert style EC-U, single-end configuration

Compatibility

Designed as an OEM-style replacement cutoff insert for Beyond Evolution series toolholders accepting insert seat size 3 and EC-U insert style geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or removing the insert. Use the appropriate torque wrench and clamping hardware specified for the Beyond Evolution toolholder to avoid insert rocking or premature failure. Do not exceed the cutting parameters appropriate for the workpiece material and machine rigidity.
