The HERTEL H05765953 is a laydown threading insert designed for right-hand external UN thread cutting at 6 threads per inch (TPI). Built from solid carbide with a TiC/TiN coating, this insert delivers consistent thread form geometry and wear resistance in production turning applications. The 22ER insert style seats in a laydown position and is rated under HERTEL's HG330TR grade, suited for threading steel and similar materials. With a 1/2-inch inscribed circle and 0.187-inch thickness, it fits standard 22ER toolholders common in CNC and manual lathe setups. Licensed machinists and CNC operators install this insert during threading operations on lathes equipped for external UN profiles.
This insert is intended for external threading operations producing Unified National (UN) thread forms at 6 TPI, typically encountered on larger-diameter fasteners, pipe fittings, and industrial hardware. It is appropriate for use in both production shop and job-shop environments where consistent thread accuracy is required on steel and similarly machinable materials. The right-hand orientation and 22ER style designate it for standard external threading toolholder configurations. The TiC/TiN finish extends tool life in moderate-speed cutting conditions where heat buildup and edge wear are primary concerns.
Designed for use in 22ER-style laydown threading toolholders configured for right-hand external UN thread forms.
This insert is installed by machinists and CNC operators on lathes performing external threading passes. Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torx or hex key specified by the toolholder manufacturer to secure the insert clamp - do not overtighten by estimate. Inspect the insert pocket for chips or debris before seating to ensure full, flat contact and accurate thread geometry.
