Kennametal 1796511 Threading Insert KC5010 Acme 6 Tpi

Product Description

The KENNAMETAL 1796511 is a carbide threading insert in the Top Notch series, designed for cutting Acme thread forms at 6 threads per inch (TPI). Coated with TiAlN via a PVD process, this left-hand insert delivers wear resistance and thermal stability during demanding threading operations. The included angle measures 29 degrees, consistent with the Acme thread standard. The insert tip measures 0.1492 inches from tip to top, and the cutting tip width is 0.0567 inches, making it suitable for precise internal and external thread profiles. Machinists and tool-and-die professionals use this insert in CNC lathes and manual turning centers equipped with Top Notch toolholders.

This insert handles both internal and external Acme thread applications on a variety of workpiece materials, corresponding to material grades C3 and C4. Left-hand orientation makes it appropriate for threading operations where conventional right-hand inserts cannot be applied, such as reverse-thread assemblies or specific fixture setups. The TiAlN finish provides oxidation resistance at elevated cutting temperatures, extending tool life in production threading environments.

Key Features

• Carbide substrate with TiAlN PVD finish for extended wear resistance
• Left-hand insert orientation for reverse-thread or specialty threading applications
• 29-degree included angle conforming to Acme thread standard
• 6 TPI internal pitch for Acme thread form cutting
• Handles both internal and external thread types in a single insert style
• Top Notch series compatibility for use with matching KENNAMETAL toolholders

Compatibility

Designed for use with KENNAMETAL Top Notch series threading toolholders. Suitable for Acme thread form applications requiring a left-hand, 6 TPI insert in material grades C3 and C4.

Installation Notes

This insert is installed by a machinist into a compatible Top Notch series toolholder; confirm the toolholder is rated for the insert size before seating. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench for the clamping screw and handle carbide inserts carefully to avoid chipping cutting edges. Verify thread form, hand orientation, and TPI against the workpiece drawing before beginning the cut.
