Carmex 22IR6ACMEBXC Threading Insert 6 Tpi 1/2 in Ic

Product Description

The CARMEX 22IR6ACMEBXC is a solid carbide laydown threading insert designed for cutting internal Acme threads on CNC and manual lathes. Built to the 22 IR insert style, it cuts at 6 threads per inch (TPI) with a 29-degree included angle that matches the Acme thread form precisely. The insert measures 0.500 inches inscribed circle (IC) and 0.187 inches thick. A PVD-applied titanium nitride (TiN) coating improves surface hardness and wear resistance, extending tool life across a wide range of workpiece materials. Licensed machinists, toolroom operators, and CNC programmers working in production threading applications install this insert in compatible 22 IR right-hand boring and threading toolholders.

This insert is suited for internal Acme thread production in materials coded H, K, M, N, P, and S, covering steels, stainless alloys, aluminum, nonferrous metals, titanium, and high-temperature alloys. It is used in applications where precision Acme thread forms are required, such as lead screws, power transmission components, and actuator components machined on turning centers or engine lathes. Right-hand cutting orientation makes it compatible with conventional forward-feed threading passes on standard setups.

Key Features

• Solid carbide substrate for rigidity and dimensional stability under interrupted cuts
• PVD TiN coating for improved hardness and reduced built-up edge on a broad material range
• 29-degree included angle ground to Acme thread standard for accurate thread form
• 6 TPI pitch suits common Acme lead screw and power-transmission threading applications
• Right-hand internal cut geometry compatible with standard boring bar and threading toolholder setups
• Meets CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed for use in 22 IR style right-hand internal threading toolholders. Compatible workpiece material codes include H, K, M, N, P, and S per manufacturer classification.

Installation Notes

A qualified machinist or toolroom technician should install this insert. Power down and lock out the machine spindle before seating or indexing any insert. Verify the toolholder pocket and clamping screw are clean and free of chips before installation. Follow the toolholder manufacturer torque guidance for the clamping screw and confirm insert seating before taking a threading pass.
