Kennametal 4176041 Grooving Insert NG3062K KCU10 Carbide

Product Description

The KENNAMETAL 4176041 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. It carries the KCU10 manufacturer grade with a Physical Vapor Deposition (PVD) AlTiN coating, which provides thermal resistance and extended tool life in interrupted cuts and difficult-to-machine alloys. The insert delivers a 0.0622-inch cutting width and a maximum depth of cut of 0.0941 inches, making it suited for narrow, accurate grooves. It is installed and maintained by machinists and tool-room technicians working in production or job-shop environments.

This insert fits within the Top Notch series tooling system and is configured for right-hand cutting with a neutral rake angle and a 0.0075-inch corner radius. It is applicable to grooving operations in ferrous and non-ferrous materials where a K-style chip breaker geometry is required to control chip flow. Typical applications include OD grooving, profiling, and light parting on precision turned components in aerospace, automotive, and general metalworking.

Key Features

• KCU10 grade solid carbide substrate with PVD AlTiN coating for heat and wear resistance
• 0.0622-inch cutting width for tight-tolerance narrow grooves
• Maximum depth of cut range of 0.0750 to 0.1000 inches
• K-style chip breaker geometry for reliable chip control
• Right-hand orientation with neutral rake and 0-degree lead angle
• 0.0075-inch corner radius for controlled groove floor finish
• NG insert style, compatible with Top Notch series toolholders

Compatibility

Designed for use with Top Notch series toolholders that accept NG-style grooving inserts, insert size 3062. Cross-reference manufacturer number NG3062R/LK for toolholder compatibility verification.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine fully stopped and the spindle locked. Ensure the insert pocket and clamping screw are free of chips and debris before seating the insert. Torque the clamp to the toolholder specification provided by KENNAMETAL for the Top Notch system. Confirm cutting edge orientation and depth-of-cut settings against the programmed toolpath before resuming operation.
