Kennametal 1818876 Grooving Insert KC5025 Solid Carbide

Product Description

The KENNAMETAL 1818876 is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. Manufactured in the NU3125 style within the Top Notch series, this insert carries a TiAlN coating applied via PVD process, providing thermal resistance and extended tool life in demanding cutting conditions. It is configured for left-hand cutting, with a 3.18 mm cutting width and a maximum depth of cut of 4.78 mm. A corner radius of 1.19 mm and a neutral rake geometry round out the key dimensional attributes. Machinists, tool-and-die technicians, and CNC operators in production and job-shop environments typically source and install this insert.

This insert is suited for grooving, recessing, and cutoff applications in ferrous and non-ferrous materials where consistent groove geometry is required. The KC5025 grade with PVD TiAlN finish performs well in interrupted cuts and moderate-to-high cutting speeds. The Top Notch series interface provides secure, repeatable seating in compatible Top Notch-style toolholders. It is sized as an insert size 3125 and is supplied individually, with a minimum order quantity of 5 units.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert securely. Inspect the toolholder pocket for wear or debris before seating a new insert.
