Built to the Top Notch series standard, it carries a KCU10 grade designation and an AlTiN finish applied via PVD coating, which extends tool life in abrasive and interrupted-cut applications. The insert delivers a 2.67 mm cutting width with a maximum depth of cut of 3.81 mm, making it well-suited for shallow-to-medium groove profiles. It is installed and changed by machinists and tooling technicians using a mechanical clamp-style holder.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in Top Notch series clamp-style grooving toolholders configured for left-hand cutting. It fits typical applications on production turning equipment in metalworking environments, including both job shop and high-volume manufacturing settings. The metric sizing designation NG3105 and the left-hand orientation make it appropriate for grooving operations where the tool approaches from the left side of the workpiece. Material grades C3 and C4 indicate suitability for turning steel, cast iron, and similar ferrous workpiece materials at appropriate cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AlTiN PVD coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e2.67 mm cutting width with a maximum depth of cut range of 3.00 to 4.00 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for compatible left-hand toolholder configurations\u003c\/li\u003e\n  \u003cli\u003e0.19 mm corner radius for controlled groove profile finish\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle geometry on the insert form\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method for positive insert seating and repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders that accept NG3105 left-hand inserts.

Seat the insert fully into the clamp pocket before tightening the clamp screw; inspect the insert seat and clamp for chips or debris before seating. Do not exceed the maximum depth of cut specification for the insert grade and workpiece material combination.
