Carmex 16ER10ACMEP25C Threading Insert 10 Tpi Acme Carbide

Product Description

The CARMEX 16ER10ACMEP25C is a solid carbide laydown threading insert designed for external Acme thread turning operations. It cuts right-hand threads at 10 threads per inch (TPI) to the Acme thread standard, with a 29-degree included angle. The insert carries a P25C manufacturer grade and a C5 material grade, with a PVD-applied TiN coating for extended tool life. The inscribed circle measures 0.3750 inches and the insert thickness is 0.1460 inches. This insert is suited for CNC lathes and manual threading applications where precise Acme thread profiles are required. Installation and use are performed by machinists and CNC operators in production or job-shop environments.

The 16ER10ACMEP25C is used in external threading operations producing Acme-profile threads at 10 TPI. The Acme thread form is common in lead screws, power transmission components, and linear actuators across both industrial and commercial equipment. This insert supports a universal primary workpiece material classification, making it applicable across a broad range of ferrous and non-ferrous materials. It is appropriate for general-purpose threading passes where a consistent, repeatable Acme profile is required on turned components.

Compatibility

Designed for use in toolholders accepting the 16ER insert style for external Acme thread turning. Verify toolholder compatibility with the 16ER insert form and inscribed circle size before installation. No specific machine or system compatibility was stated in the product data.

Installation Notes

This insert is installed by machinists or CNC operators into a compatible 16ER external threading toolholder. Ensure the machine spindle is fully stopped and the toolholder is clear of the workpiece before seating or removing the insert. Use the appropriate torque wrench for the clamping screw as specified by the toolholder manufacturer. Inspect the insert seating pocket for chips or debris before installation to ensure accurate insert positioning.
