Kennametal 1818506 Grooving Insert NG3078K KC5010 Tialn

Product Description

The KENNAMETAL 1818506 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. The insert carries a TiAlN PVD coating and a KC5010 grade designation, making it suited for demanding interrupted-cut and high-speed turning applications where wear resistance and edge integrity are critical. The cutting geometry is left-hand orientation with a 1.98 mm cutting width, a maximum depth of cut of 2.39 mm, and a positive rake angle of 10 degrees. Machining professionals and CNC toolroom technicians install this insert as a direct exchange in compatible Top Notch toolholders.

This insert is intended for use in metal-cutting environments where tight-tolerance grooving is required on ferrous and non-ferrous workpiece materials. The KC5010 grade and TiAlN coating combination is appropriate for moderate-to-high cutting speeds in both continuous and interrupted cuts. The insert size designation is 3078 within the NG style family, and the K chip breaker geometry supports controlled chip flow during shallow grooving passes. The insert is packaged individually but carries a minimum order quantity of 5 units, making it appropriate for production toolrooms maintaining insert inventory.

Key Features

• TiAlN PVD coating provides thermal barrier and oxidation resistance at elevated cutting temperatures
• KC5010 carbide grade rated for material grades C3 and C4 applications
• 1.98 mm cutting width with a maximum depth of cut range of 2.00 to 3.00 mm
• Positive rake angle (10 degrees) reduces cutting forces and promotes free cutting action
• K chip breaker geometry controls chip formation in shallow-to-medium depth grooving
• 0.19 mm corner radius minimizes stress concentration at groove walls
• Left-hand insert orientation for specific toolholder configurations

Compatibility

Designed for use in KENNAMETAL Top Notch series NG-style toolholders. Consult the toolholder documentation to confirm left-hand insert seating and NG3078 pocket compatibility before installation.

Installation Notes

Insert replacement should be performed by a qualified CNC machinist or toolroom technician with the machine spindle fully stopped and the turret in a safe index position. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not overtighten the clamp screw, as solid carbide inserts are brittle and can fracture under uneven clamping load. Inspect the insert pocket for debris, chips, and seating-surface wear before installing a new insert. Verify left-hand orientation and chip breaker alignment against the toolholder documentation prior to resuming cutting operations.
