Hertel H08701575 Threading Insert 16ERA60 HG630TR 48-16 Tpi

Product Description

The HERTEL H08701575 is a solid carbide laydown threading insert designed for external thread cutting on CNC lathes and turning centers. Cataloged as insert style 16ERA60 in grade HG630TR, this insert carries a TiC/TiN multilayer coating that improves wear resistance and extends cutting life across a broad range of workpiece materials. It cuts right-hand external partial-profile 60-degree threads and covers a thread pitch range of 48 to 16 TPI, equivalent to 0.50 to 1.50 mm pitch. The inscribed circle measures 3/8 inch (0.3750 inch decimal) and the insert thickness is 0.1460 inch. It is sized and styled for use by machinists and CNC operators in production threading applications.

This insert is suited for external threading operations on ferrous and non-ferrous materials in precision machining environments. The partial-profile geometry allows it to cover the 48-16 TPI range without a dedicated single-pitch tool, making it practical for job shops and production floors that run varied thread specifications. The right-hand orientation and 0-degree relief angle are consistent with standard laydown insert pockets on industry-common threading toolholders.

• Grade HG630TR for consistent performance across threading applications

Compatibility

Designed for use in laydown threading toolholders accepting 16ER-style inserts with a 3/8-inch inscribed circle and 0-degree relief angle. Verify holder pocket specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's seating and clamping procedures. Ensure the machine spindle is fully stopped and the tool turret is locked out before changing inserts. Use the appropriate torx or hex key to achieve proper clamping torque as specified by the toolholder manufacturer - do not overtighten, as this can chip the carbide substrate. Confirm insert orientation and thread direction before commencing a threading pass.
