Kennametal 1817662 Grooving Insert KC5025 Tialn Left Hand

Product Description

The KENNAMETAL 1817662 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and cutoff operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which improves wear resistance and thermal stability during interrupted or continuous cuts. The insert is left-hand orientation with a 4.8 mm cutting width and a maximum depth of cut of 9.53 mm. A positive rake angle of 10 degrees and a K-style chip breaker promote clean chip evacuation in a range of metalworking materials. This insert is installed by machinists and CNC operators working in production and job-shop environments.

The 1817662 is suited for grooving applications where controlled chip flow and dimensional accuracy are critical. Its 4.8 mm cutting width and 0.57 mm corner radius make it appropriate for precision groove profiles in ferrous and non-ferrous workpiece materials. The KC5025 grade targets general-purpose turning and grooving with a balance of toughness and wear resistance. The Top Notch series insert seat size 4 and NFD insert style ensure compatibility with corresponding Top Notch toolholders. Maximum depth of cut range spans 5.00 mm to 10.00 mm, suitable for moderate grooving depths in production runs.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly in the Top Notch toolholder pocket and verify the clamping screw torque per the toolholder manufacturer documentation. Inspect the insert seat for chips or debris before seating to prevent microfracture of the carbide on first cut.
