Hertel H08701591 Threading Insert 16ER 60 Deg 3/8 Ic

Product Description

The HERTEL H08701591 is a solid carbide laydown threading insert designed for external thread cutting on CNC lathes and manual turning centers. This insert carries the 16ER style designation with a 60-degree partial profile thread form, covering a range of 48 to 16 threads per inch and a metric pitch range of 0.50 to 1.50 mm. The insert features a TiC/TiN multilayer coating for improved wear resistance and longer tool life in ferrous and non-ferrous materials. With a 3/8 inch inscribed circle and a thickness of 0.146 inches, it seats securely in compatible 16ER toolholders. Right-hand cutting geometry is standard on this insert.

This threading insert is suited for external threading operations in production turning environments, including job shops, aerospace component machining, and general manufacturing. It handles a broad TPI range, making it practical for threading standard unified and metric-compatible fastener profiles without changing inserts for every pitch. Machinists and CNC programmers working with materials from mild steel to alloy steel will find the HG330TR grade appropriate for a range of cutting conditions. Each package contains one insert, and orders must be placed in multiples of ten units.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and manufacturer-specified insert screw to avoid cracking the carbide substrate. Verify toolholder pocket condition and clamp integrity before resuming cutting operations.
