Kennametal 4176124 Grooving Insert NG3062K KCU10 Carbide Altin

Product Description

The KENNAMETAL 4176124 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. This left-hand insert carries a KCU10 grade designation and an AlTiN coating applied via PVD process, delivering elevated heat and wear resistance at cutting speeds common in production turning. The cutting width measures 0.0622 inches with a maximum depth of cut of 0.1252 inches, placing it firmly in the 0.1000 to 0.1500 inch depth-of-cut range. A 0.0075-inch corner radius and neutral rake geometry round out the key cutting parameters. Installation is performed by machinists and CNC programmers in metalworking shops.

This insert is suited for grooving, recessing, and light parting applications in materials where AlTiN PVD coating provides a performance advantage, such as steels, stainless steels, and hardened alloys. The NG insert style mounts in compatible Top Notch toolholders. The K chip breaker geometry assists in controlling chip flow during grooving passes. With a 55-degree included angle and a lead angle of 0 degrees, this insert is built for straight-wall groove profiles. It is a single-use, non-multi-use insert with no full-radius edge, sold in packages of one with a minimum order quantity of five units.

Key Features

• Solid carbide substrate with KCU10 manufacturer grade for consistent edge integrity
• AlTiN coating via PVD process for heat resistance and extended tool life
• Left-hand cutting orientation for specific toolholder configurations
• 0.0622-inch cutting width and 0.1252-inch maximum depth of cut
• K chip breaker geometry for controlled chip evacuation in grooving operations
• Neutral rake angle and 0-degree lead angle for straight-wall groove profiles

Compatibility

Designed for use in Top Notch series toolholders that accept the NG insert style. Verify toolholder designation matches left-hand insert orientation before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer torque and clamping procedures. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Do not exceed the published depth-of-cut range for this insert geometry.
