Kennametal 6442488 Cutoff Insert KCU25 Solid Carbide 2 Mm

Product Description

The KENNAMETAL 6442488 is a solid carbide cutoff insert from the Beyond Evolution series, designed for parting and grooving operations on CNC lathes and turning centers. Carrying grade designation KCU25 with a PVD-applied Al2O3 coating, this insert delivers reliable edge life in a range of workpiece materials. The EC-style insert features a 2 mm cutting width, a neutral lead angle, a 0-degree lead angle, and a 2-degree relief angle with a CF chipbreaker geometry. It is installed by machinists and CNC operators performing precision cutoff and grooving work.

This insert is suited for parting and grooving applications in production and job-shop turning environments. The CF chipbreaker geometry promotes chip control in light to moderate cutting conditions. The KCU25 PVD grade is selected for applications where sharp cutting edges and coating adhesion are priorities. Each package contains one insert, with a minimum order quantity of 10 units. The insert seat size is 2, compatible with toolholders accepting EC-style inserts in that seat designation.

Key Features

• Solid carbide substrate with PVD-applied Al2O3 coating for enhanced edge integrity
• 2 mm cutting width for precise parting and grooving cuts
• CF chipbreaker geometry for effective chip control during cutoff operations
• Neutral hand and 0-degree lead angle for straight, balanced cutting action
• 2-degree relief angle reduces flank rubbing and extends tool life
• Beyond Evolution series engineering for consistent dimensional accuracy

Compatibility

Designed for use with EC-style cutoff and grooving toolholders accepting insert seat size 2. Confirm toolholder seat designation and insert style compatibility before installation. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked before insert exchange. Use the appropriate torque wrench and insert clamping screw specified by the toolholder manufacturer — do not overtighten or use impact tools on clamping hardware. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Handle carbide inserts with care, as edges are brittle and susceptible to chipping from impact.
