Kennametal 1799463 Threading Insert NA6L2 KC5025 Left Hand

Product Description

The KENNAMETAL 1799463 is a carbide threading insert in the Top Notch series, designed for cutting Acme threads in both internal and external applications. Manufactured to the NA6L2 geometry in the KC5025 grade with a TiAlN PVD finish, this insert handles left-hand Acme thread profiles at 2 TPI with an included angle of 29 degrees. The carbide substrate with TiAlN coating provides wear resistance and thermal stability in demanding threading operations. The insert measures 0.3831 inches thick, with a tip-to-top height of 0.2831 inches and a cutting tip width of 0.1803 inches. Licensed machinists and CNC lathe operators working on Acme-threaded components install this insert in compatible Top Notch toolholders.

This insert is suited for threading operations on Acme-profile threads in both internal and external configurations. The left-hand orientation and 2 TPI pitch make it applicable in lead screw, power screw, and actuator shaft applications common in industrial machining environments. It is appropriate for use on a range of workpiece materials corresponding to C2 and C6 material grades, covering general-purpose ferrous and non-ferrous cutting. The insert is sized at Insert Size 6 and fits Top Notch series toolholders designed for that insert class.
