Carmex 1/2INRHN60MXC Laydown Threading Insert 1/2 in Ic

Product Description

The CARMEX 1/2INRHN60MXC is a solid carbide laydown threading insert designed for right-hand internal threading operations. It carries a partial profile 60-degree thread form, covering a range of 7 to 5 TPI (3.50 to 5.00 mm pitch), making it suitable for machining a broad span of thread sizes in a single insert grade. The insert features a TiN coating applied via PVD process, which improves surface hardness and wear resistance. With a 1/2-inch inscribed circle and a thickness of 0.187 inches, this insert seats in standard 22IR-style toolholders. It is intended for use by machinists and toolroom professionals on CNC lathes and threading centers.

This insert is rated for universal workpiece material compatibility, covering material groups H, K, M, N, P, and S under ISO classification. That range includes carbon steels, alloy steels, stainless steels, cast irons, non-ferrous metals, and heat-resistant superalloys. The partial profile 60-degree geometry allows the insert to cut multiple thread pitches without requiring a dedicated full-profile insert for each size, reducing tooling inventory. It is well suited for both production threading and job-shop environments where thread size variety is common.

Compatibility

Designed for use in 22IR-style internal threading toolholders. Compatible with right-hand boring bar and toolholder systems that accept 22IR laydown threading inserts with a 1/2-inch inscribed circle.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the manufacturer-recommended torx or hex key to secure the insert clamp screw to the toolholder without overtightening. Verify insert orientation and confirm right-hand thread direction matches the programmed toolpath before resuming cutting operations.
