Hertel 16IRA60HG225TR Threading Insert Solid Carbide 48-16 Tpi

Product Description

The HERTEL 16IRA60HG225TR is a solid carbide laydown threading insert designed for internal partial profile 60-degree thread cutting. It carries a TiAlN coating applied via PVD process, which provides heat resistance and extended tool life in demanding threading operations. The insert covers a range of 48 to 16 TPI and a metric pitch range of 0.50 to 1.50 mm. With a 3/8 inch inscribed circle and a thickness of 0.146 inches, this is a right-hand insert sized for precision internal threading on CNC lathes and manual turning centers. It is installed by machinists and tooling specialists in production and job shop environments.

This insert is suited for internal threading operations on ferrous and non-ferrous materials where a 60-degree thread form is required. The 16IR insert style fits compatible toolholders designed for that seat geometry. The broad TPI range makes it a practical choice for shops threading multiple fastener standards without frequent insert changes. It is commonly used in production turning on CNC equipment as well as manual lathes where consistent thread profile accuracy is needed across batches.

Installation Notes

This insert is installed by qualified machinists or tooling technicians. Power down and lock out the machine before changing inserts. Use the correct torque driver or clamp screw specified by the toolholder manufacturer to seat the insert — do not overtighten. Inspect the toolholder pocket for wear or damage before installing a new insert to ensure proper seating and thread accuracy.
