Kennametal 1818008 Grooving Insert NG2062K KC5025 Carbide

Product Description

The KENNAMETAL 1818008 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving operations on CNC lathes and turning centers. Grade KC5025 carbide substrate with a PVD-applied TiAlN coating provides wear resistance and thermal stability across a range of workpiece materials. The insert features a 1.58 mm cutting width and a maximum depth of cut of 2.79 mm, with a positive 10-degree rake angle and a K-style chip breaker that promotes efficient chip evacuation. A 0.19 mm corner radius and a 55-degree included angle define the cutting geometry. This insert is a right-hand configuration and is sized as an NG 2062 style, suited for tight-tolerance grooving and parting applications performed by machinists and CNC tooling technicians.

The 1818008 fits standard Top Notch grooving toolholders that accept the NG 2062 insert style. It is appropriate for external grooving on ferrous and non-ferrous materials in both light and moderate cutting conditions. The KC5025 grade with TiAlN finish is well-suited for interrupted cuts, dry machining, and applications where coolant use may be limited. Material grade classification is C2 and C6, covering a broad range of turning and grooving work on steel, cast iron, and similar workpiece materials. This insert is intended for production environments where repeatable grooving geometry and consistent tool life are required.

Key Features

• Solid carbide construction, KC5025 grade with PVD TiAlN coating for wear and heat resistance
• 1.58 mm cutting width for precise narrow groove profiles
• Maximum depth of cut of 2.79 mm within the 2.00 to 3.00 mm depth range
• Positive 10-degree rake angle with K-style chip breaker for controlled chip flow
• 0.19 mm corner radius and 55-degree included angle for defined groove geometry
• Right-hand insert orientation, NG 2062 insert size in the Top Notch series

Compatibility

Designed for use in Top Notch series grooving toolholders that accept the NG 2062 insert style. The manufacturer cross-reference number is NG2062R/LK.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Ensure the toolholder pocket is clean and free of chips or debris before seating the insert to maintain proper geometry and clamping force. Do not exceed the rated maximum depth of cut for this insert style, as overloading can cause premature edge failure or insert fracture.
