Kennametal 4176034 Grooving Insert NG3047 KCU10 Solid Carbide

Product Description

The KENNAMETAL 4176034 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries a KCU10 manufacturer grade with a PVD-applied AlTiN coating that provides thermal resistance and extended tool life in ferrous and non-ferrous materials. The insert is left-hand orientation, delivers a 1.19 mm cutting width, and supports a maximum depth of cut of 1.91 mm. The double-ended design adds usable cutting edges per insert. Machining professionals installing this insert work with a clamp-style holding method on compatible Top Notch toolholders.

This insert is suited for precision grooving applications on manual and CNC turning equipment in both production shops and maintenance machining environments. Its NG insert style, size 3047, and insert seat size 3 make it a fit for toolholders configured for the Top Notch system. The 55-degree included angle and 0.19 mm corner radius are appropriate for groove geometry where controlled radius at the groove base is required. The C3 and C4 material grades indicate suitability for cast iron and non-ferrous applications in addition to general steel turning.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and all motion is locked out before seating or removing the insert. Verify the toolholder seat is clean and free of debris before clamping to ensure proper seating and accurate cutting geometry. Follow the toolholder manufacturer torque specifications for the clamping screw — do not over-tighten.
