Kennametal 4176055 Grooving Insert NG3094K KCU10 Solid Carbide

Product Description

The KENNAMETAL 4176055 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured to the Top Notch series standard, it carries the KCU10 grade designation and features a physical vapor deposition (PVD) AlTiN coating for improved wear resistance and thermal stability at elevated cutting speeds. The insert has a 0.0941-inch cutting width, a maximum depth of cut of 0.15 inches, and a 0.0075-inch corner radius. It is a right-hand, double-end insert with a neutral rake and an included angle of 55 degrees. Machinists and CNC tool setters working in job shops or production turning environments are the typical users.

This insert is suited for grooving, slotting, and light parting applications on ferrous and non-ferrous workpiece materials where a narrow cutting width and controlled chip formation are required. The K chip breaker geometry is optimized for these cut profiles. The Top Notch series toolholder system uses a seat size 3 interface, which governs compatible insert holders. The insert is sold individually but must be ordered in multiples of 5 to meet the minimum order quantity requirement.

Key Features

• KCU10 solid carbide grade with PVD AlTiN coating for extended tool life at high cutting temperatures
• 0.0941-inch cutting width with a 0.0075-inch corner radius for tight-tolerance groove profiles
• Maximum depth of cut of 0.15 inches, with a rated range up to 0.200 inches
• K chip breaker geometry provides controlled chip evacuation during narrow grooving operations
• Double-end design allows both ends of the insert to be used before replacement
• Neutral rake and 0-degree lead angle for stable radial entry into the workpiece

Compatibility

Designed for use with Top Notch series toolholders that accept a seat size 3 insert interface. The MSC and manufacturer cross-reference number for this insert is NG3094R/LK.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tool setter following the toolholder manufacturer's torque and clamping procedures. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for debris or wear before seating a new insert. Do not force the insert into the seat; proper seating is confirmed by full contact with all pocket walls and correct clamping force per the holder specification.
