Carmex 16ER8ACMEBXC Threading Insert 8 Tpi Acme Solid Carbide

Product Description

The CARMEX 16ER8ACMEBXC is a solid carbide laydown threading insert designed for cutting external Acme threads at 8 threads per inch. The insert features a 29-degree included angle consistent with the Acme thread standard and carries a TiN coating applied via PVD process, improving surface hardness and tool life across a wide range of workpiece materials. At 3/8 inch inscribed circle and 0.146 inches thick, this is a 16 ER-style insert suited for use in compatible laydown threading toolholders. It is installed by machinists and CNC operators in production and job-shop turning environments where precise Acme thread form is required.

This insert is intended for right-hand external Acme threading operations on lathes and CNC turning centers. The universal primary workpiece material classification covers steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and hardened materials, making it adaptable across a broad range of turning applications. Typical uses include lead screws, power screws, and other components requiring an Acme thread form. The BXC manufacturer grade designation indicates the specific substrate and coating combination selected for this insert.

Compatibility

Designed for use in 16 ER-style laydown threading toolholders that accept a 3/8 inch inscribed circle insert. Confirm toolholder seat geometry and insert pocket dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine is fully stopped and in a safe state before changing inserts. Seat the insert firmly in the toolholder pocket and secure with the appropriate clamping screw to the toolholder manufacturer's specification. Verify thread form and pitch with a thread gauge before committing to a production run.
