Carmex 22ER4.0ISOMXC Laydown Threading Insert Solid Carbide

Product Description

The CARMEX 22ER4.0ISOMXC is a solid carbide laydown threading insert designed for external ISO thread turning operations on CNC lathes and threading machines. Built from micrograin solid carbide with a PVD-applied TiN coating, this insert delivers consistent thread form and extended tool life when cutting right-hand external ISO threads at a 4.0 mm pitch. The 1/2 inch inscribed circle and 0.187 inch thickness match standard 22-series toolholder pockets. The MXC grade designation indicates a micrograin carbide substrate suited for threading ferrous and non-ferrous materials at moderate to high cutting speeds.

This insert is used in production and job-shop turning environments where repeatable ISO thread profiles are required. It is suited for external threading passes on shafts, fasteners, fittings, and threaded connectors. The right-hand cut orientation is standard for conventional external threading on most CNC and manual lathes. Machinists and tool-and-die professionals working with ISO metric thread standards will find this insert a direct fit for 22ER-style toolholders.

Key Features

• Solid micrograin carbide substrate for improved edge strength and wear resistance
• PVD TiN coating reduces friction and extends insert life in external threading applications
• 4.0 mm pitch ISO thread profile for standard metric external threads
• Right-hand cut orientation compatible with conventional lathe rotation
• 1/2 inch inscribed circle fits standard 22ER toolholder pockets
• Laydown seating style provides rigid, repeatable insert positioning

Compatibility

Designed as an OEM-style replacement or direct-fit insert for 22ER-series external threading toolholders accepting a 1/2 inch inscribed circle laydown insert with 0.187 inch thickness.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the toolholder pocket is clean and free of chips before installing to maintain proper seating and thread-form accuracy. Follow the toolholder manufacturer torque guidelines for the clamping screw and verify thread profile with a thread gauge before running production.
