Carmex 22UIR4ACMEMXC Threading Insert 4 Tpi 1/2 in Ic

Product Description

The CARMEX 22UIR4ACMEMXC is a solid carbide laydown threading insert designed for cutting internal Acme threads. It operates at 4 threads per inch (TPI) with a 1/2 inch inscribed circle and a thickness of 0.187 inches. The insert features a PVD-applied titanium nitride (TiN) coating for improved wear resistance and tool life. Right-hand cutting geometry makes it suitable for standard internal Acme thread applications. This insert is used by machinists and tooling professionals in CNC lathe and threading operations across a wide range of workpiece materials.

This insert is intended for internal Acme thread profiles at 4 TPI, covering a universal range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys as indicated by material codes H, K, M, N, P, and S. It fits toolholders designed for the 22U insert style and is appropriate for both production and job-shop threading operations in horizontal and vertical turning centers. The right-hand orientation suits the majority of standard lathe threading setups.

Compatibility

Designed for use in 22U-style insert toolholders configured for internal Acme threading. Compatible with workpiece material grades H, K, M, N, P, and S per the manufacturer specification.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before changing inserts. Seat the insert fully and securely in the toolholder pocket using the appropriate torx or clamping screw - do not overtighten. Verify thread form and pitch with a thread gauge before running production parts.
