Carmex 22ERN60P30 Threading Insert 1/2 Ic Solid Carbide P30

Product Description

The CARMEX 22ERN60P30 is a solid carbide, uncoated laydown threading insert designed for external right-hand thread cutting operations. It features a 60-degree included angle and a 1/2-inch inscribed circle, making it suitable for partial profile threading across a wide range of thread pitches. At 0.187 inches thick and weighing approximately 0.0235 pounds, this insert seats in standard 22ER-style toolholders. Manufactured to P30 grade with a C5 material classification, it is built for productive threading in universal workpiece materials without the need for a coating. This insert is a go-to choice for machinists and toolroom technicians running external threading passes on CNC lathes and manual turning centers.

This insert is used for external right-hand threading in general-purpose turning applications. It covers a thread pitch range of 3.50 mm to 5.00 mm (approximately 5 to 7 TPI), making it well-suited for coarse-pitch thread profiles commonly encountered in production machining. Compatible workpiece materials span a broad range, including steels, stainless steels, cast iron, non-ferrous metals, high-temperature alloys, and other materials covered under material codes H, K, M, N, P, and S. It is appropriate for both production and job-shop environments where threading inserts must handle diverse material requirements.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the appropriate torx or clamping key for the toolholder style to achieve proper insert retention without over-torquing the clamp screw. Verify insert orientation and seating before resuming threading operations.
