Hertel H05767256 Threading Insert 16 Tpi Acme Solid Carbide

Product Description

The HERTEL H05767256 is a laydown threading insert designed for external Acme thread cutting on CNC lathes and threading operations in machine shops and production environments. Built from solid carbide with a TiC/TiN coating, this insert delivers wear resistance and edge retention on a range of workpiece materials. The insert follows the 16ER style designation and produces right-hand external Acme threads at 16 threads per inch. The inscribed circle measures 0.375 inches and the insert thickness is 0.146 inches. A relief angle of 0 degrees is standard for this style. Licensed machinists and CNC operators working in metalcutting trades are the primary installers of this insert.

This threading insert is suited to external Acme thread applications found in lead screw production, power transmission components, and general precision machining. The Acme thread standard is widely used where power and motion transfer require a trapezoidal thread profile. The 16 TPI pitch is common in medium-duty threading work. This insert is sold individually per package but carries a minimum order quantity of 10 units, making it appropriate for shop-stocking and production runs rather than single-job use.

Installation Notes

This insert is installed by qualified machinists or CNC operators. Power down and lock out the machine before changing inserts. Use the correct torque wrench and manufacturer-specified clamp screws to seat the insert firmly without over-tightening. Inspect the insert pocket for chips or damage before seating a new insert, and verify thread pitch and hand orientation match the job requirements before cutting.
