Kennametal 1113217 Grooving Insert NR3047 K313 Carbide

Product Description

The KENNAMETAL 1113217 is a solid carbide grooving insert designed for external grooving and parting operations on CNC lathes and turning centers. Manufactured to the NR insert style in the Top Notch series, this uncoated bright-finish insert features a 2.39 mm cutting width and a maximum depth of cut of 3.81 mm. The full-radius geometry with a 1.19 mm corner radius produces clean, consistent groove profiles. Carrying a K313 manufacturer grade, the insert is suited for machining cast iron, hardened steels, and abrasive materials where an uncoated carbide substrate provides the necessary wear resistance. Licensed machinists and CNC operators install this insert in compatible Top Notch toolholders.

This insert is used in precision turning and grooving applications on both manual and CNC lathes. The right-hand cutting orientation fits standard right-hand Top Notch grooving toolholders. The neutral rake and full-radius profile make it well suited for groove finishing passes, undercut work, and light parting operations in production and job-shop environments. The metric insert size designation is 3047, and the insert is sold individually with a minimum order quantity of 5 units.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the toolholder secured in the turret before seating or replacing the insert. Ensure the insert pocket and clamping screw are free of chips and debris before seating the insert. Follow the toolholder manufacturer torque guidance for the clamping screw to avoid insert cracking or improper seating.
