Hertel H08703373 Laydown Threading Insert 22IR 60 Degree

Product Description

The HERTEL H08703373 is a solid carbide laydown threading insert designed for internal partial profile threading operations on CNC lathes and manual threading equipment. Grade HG630TR with a TiC/TiN multilayer coating provides wear resistance and heat tolerance suited to threading ferrous and non-ferrous materials. The 22IR insert style features a 60-degree thread form angle, a 1/2-inch inscribed circle, and a thickness of 0.187 inches. Coverage spans 7 to 5 threads per inch, corresponding to a pitch range of 3.50 to 5.00 mm. Right-hand cutting orientation. Licensed machinists and CNC operators in production and job-shop environments install this insert.

This threading insert is applied in internal threading applications where a partial profile 60-degree form is required. Typical use cases include threading bores on components such as hydraulic fittings, couplings, and precision mechanical assemblies. The 22IR insert style seats in compatible laydown-style toolholders designed for that insert geometry. The HG630TR grade is suited for medium to moderate production runs where coating durability is a priority. Both production machinists and tool-and-die professionals use this insert in turning centers and engine lathes.

Compatibility

Designed for use in laydown-style internal threading toolholders that accept the 22IR insert style with a 1/2-inch inscribed circle and 0.187-inch thickness.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's seating and clamping specifications. Power down and lock out the machine before changing inserts. Inspect the toolholder pocket and clamping screw for wear or damage before seating a new insert. Do not exceed the recommended depth of cut or feed rate for the insert grade and workpiece material combination.
