Kennametal 1793811 Cutoff Insert KC5025 Carbide 5mm

Product Description

The KENNAMETAL 1793811 is a carbide cutoff and grooving insert in the A2 series, designed for precision parting and groove operations on CNC lathes and turning centers. It carries the grade designation KC5025 with a TiAlN coating applied via PVD process, delivering wear resistance and thermal stability in demanding turning applications. The insert features a 5 mm cutting width, a neutral lead angle, and a 2-degree relief angle with a CR chipbreaker geometry. The corner radius measures 0.0118 inches (0.30 mm), promoting controlled chip flow and consistent surface finish at the groove floor. Licensed machinists and CNC turning specialists are the primary installers of this insert.

This insert is suited for cut-off and grooving applications in both production and job-shop environments. The A2 series clamp-style holding method provides rigid, repeatable seating in compatible toolholders. With a material grade rating of C2 and C6, it is appropriate for use on a range of workpiece materials including steel, cast iron, and non-ferrous alloys. The insert seat size is 5, corresponding to standard A2-series toolholder pockets. It is sold individually but must be ordered in multiples of 10.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine powered off and all spindle motion stopped. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket for debris or wear before seating a new insert. Never exceed the cutting parameters recommended for the KC5025 grade and workpiece material combination.
