Carmex 22ER6ACMEMXC Threading Insert 6 Tpi Solid Carbide

Product Description

The CARMEX 22ER6ACMEMXC is a solid carbide laydown threading insert designed for external Acme thread forms at 6 threads per inch. It features a 29-degree included angle, a 1/2 inch inscribed circle, and a 0.187 inch thickness. The insert is finished with a PVD-applied TiN coating and carries a micrograin carbide grade designation of MXC, which supports consistent thread profile accuracy under demanding cutting conditions. This insert is installed by machinists and CNC lathe operators working in precision threading applications across a wide range of workpiece materials.

The 22ER6ACMEMXC is suited for right-hand external Acme threading operations on CNC and manual lathes. Its universal primary workpiece material classification covers a broad range of material groups including aluminum alloys, cast iron, stainless steel, steel, titanium alloys, and heat-resistant superalloys. It is a standard choice for threading applications in industries requiring the Acme thread standard, such as lead screws, power transmission components, and linear motion hardware. The insert seats in 22 ER-style toolholders designed for laydown insert geometry.

Key Features

• Solid micrograin carbide construction with MXC manufacturer grade for thread profile stability
• PVD-applied TiN coating for extended tool life and reduced built-up edge
• External Acme thread form at 6 TPI with a 29-degree included angle
• 1/2 inch inscribed circle and 0.187 inch thickness for 22 ER-style holders
• Right-hand cutting orientation for standard external threading passes
• Universal material compatibility covering steel, stainless, cast iron, aluminum, titanium, and superalloys

Compatibility

Designed for use in 22 ER-style laydown threading toolholders. Compatible with workpiece material groups H, K, M, N, P, and S as designated by the supplier. Suitable for Acme thread standard applications requiring 6 TPI external profiles.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the lathe or turning center is fully powered down and the spindle is locked before indexing or replacing the insert. Seat the insert fully against the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specifications. Verify thread pitch and profile with a thread gauge before committing to a full production run.
