Kennametal 5941110 Grooving Insert KCU25 3.18mm Beyond Evolution

Product Description

The KENNAMETAL 5941110 is a solid carbide grooving insert in the Beyond Evolution series, designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries a KCU25 grade designation with a PVD-applied AlTiN coating, offering strong wear resistance and thermal stability at elevated cutting speeds. The insert uses an EG-P style mount with a GUP chip breaker geometry and a neutral hand orientation. The cutting width is 3.18 mm (0.125 inches), with a maximum depth of cut of 2.20 mm (0.088 inches). A positive rake angle of 27 degrees supports free-cutting action on a range of workpiece materials. The corner radius measures 0.20 mm (0.008 inches).

This insert is suited for turning and grooving applications where consistent chip control and dimensional accuracy are critical. The GUP chip breaker geometry is optimized for light to medium grooving passes in ferrous and non-ferrous materials. Typical applications include external grooving, undercut work, and controlled-depth parting on precision turned components in production and job-shop environments. Installation is performed by licensed machinists and CNC operators familiar with indexable tooling systems.

Key Features

• KCU25 solid carbide grade with PVD AlTiN coating for extended tool life
• GUP chip breaker for controlled chip evacuation in grooving operations
• Positive rake angle of 27 degrees reduces cutting forces
• Neutral hand orientation for flexible setup on standard grooving toolholders
• 3.18 mm cutting width with a tight 0.20 mm corner radius for precision groove geometry
• Beyond Evolution series insert style EG-P for consistent indexing repeatability

Compatibility

Designed as an OEM-style indexable grooving insert for use with EG-P style grooving toolholders compatible with the Beyond Evolution series platform.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torque wrench per the toolholder manufacturer specifications and inspect the insert pocket for debris or wear before installation. Do not exceed the rated maximum depth of cut range of 2.00 mm to 3.00 mm for this insert grade and geometry.
