Kennametal 1724878 Grooving Insert NG3047K KC5010 Carbide

Product Description

The KENNAMETAL 1724878 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding cuts. The insert features a 1.19 mm cutting width and a maximum depth of cut of 1.91 mm, making it suited for precise, narrow-groove applications. The KC5010 grade with positive rake geometry delivers clean chip formation in steel, stainless, and difficult-to-machine alloys. This insert is sold individually and installed by machinists and CNC turning specialists in production and job-shop environments.

This insert is appropriate for both light-production and high-volume turning operations where consistent groove geometry and tight tolerances are required. The NG insert style and Top Notch series tooling system are common in shops running bar-fed turning centers and gang-tool lathes. The right-hand orientation suits the standard front-mounted tooling configuration on most production lathes. The K chip breaker geometry supports controlled chip evacuation at moderate feed rates. This insert is a metric-measurement-type product with an insert size designation of 3047.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and verify clamp torque per the toolholder manufacturer's specification before resuming cuts. Inspect the insert pocket and clamping screw for wear or debris prior to installation to ensure proper seating and edge repeatability.
