Kennametal 1765733 Threading Insert 12 Tpi Carbide Tialn

Product Description

The KENNAMETAL 1765733 is a carbide threading insert designed for external thread cutting on UN-standard threads at 12 TPI. Manufactured in the Top Notch series with an NTC3R insert style, this insert features a TiAlN finish applied via PVD coating, which improves wear resistance and thermal stability during high-speed threading operations. The 60-degree included angle suits standard UN thread forms. With a tip-to-top height of 0.1480 inches and a corner radius of 0.0098 inches, the geometry is optimized for right-hand external threading. Machinists and toolroom professionals install this insert into compatible Top Notch toolholders for production threading on lathes and turning centers.

This insert is suited for external threading applications on UN-standard workpieces in materials consistent with C3 and C4 material grades, covering a broad range of steels and cast irons. The KC5010 manufacturer grade with TiAlN PVD coating makes it a practical choice for finishing and semi-finishing threading passes where dimensional accuracy and thread form consistency are required. It is commonly used in job shop and production turning environments where repeatable thread quality across multiple parts is necessary.

Installation Notes

This insert is installed and replaced by a qualified machinist or toolroom technician. Power down and lock out the lathe or turning center before changing inserts. Seat the insert fully and evenly in the pocket to ensure proper clamping and thread form accuracy. Follow the toolholder manufacturer torque guidance for clamping screws and verify thread form with a thread gauge before running production.
