Insert, 11IRA60 Internal Thread, TiN Coated Carbide

The 11IRA60 TiN Coated Internal Threading Carbide Insert is suitable for both CNC and manual lathes. It has a 60° V partial profile, allowing machinists to cut a wide variety of thread pitches without changing inserts.

The pitch range of this insert is 0.5 - 1.5mm and the TPI range is 16 - 48TPI. The inscribed circle (I.C.) is 1/4".

The partial profile design (sometimes called non-cresting) only cuts the thread groove. Due to the small nose radius (0.003") a single insert can cut multiple thread pitches providing the profile angle is 60°.

The carbide substrate absorbs the cutting force and vibrations when threading steel, stainless steel and cast iron. The TiN (Titanium Nitrite) coating provides low friction and high surface hardness. Its heat and wear resistance extends the life of your cutting tool.

This insert is designed for light to medium roughing, finishing, and semi-finishing passes.

*NOTE: Make sure you get the correct inserts and retaining screws for your indexable turning tools. Our chart of indexable inserts shows which inserts and which screw to use with each of our indexable tools.
