Carmex 22ER6UNBXC Threading Insert 6 Tpi 1/2 Inch Ic

Product Description

The CARMEX 22ER6UNBXC is a solid carbide laydown threading insert designed for external UN thread cutting at 6 threads per inch. The insert features a TiN (titanium nitride) coating applied via PVD process, which improves surface hardness and wear resistance. With a 1/2 inch inscribed circle and 0.187 inch thickness, this right-hand insert fits standard laydown-style threading toolholders. It carries the BXC manufacturer grade designation. This insert is used by machinists and CNC operators on lathes and turning centers where precise external thread form and tool life are priorities.

This insert is suited for external threading operations on UN-standard thread profiles in production and job-shop environments. The 6 TPI designation targets coarser thread pitches commonly found on larger-diameter fasteners, couplings, and industrial components. The laydown style seating provides stable clamping geometry, which is important for maintaining thread form accuracy across repeated cuts. Typical users include CNC machinists, tool-and-die shops, and maintenance shops cutting replacement or custom-threaded components.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading applications
• TiN coating via PVD process improves hardness and reduces cutting edge wear
• 6 TPI external UN thread form for coarse-pitch applications
• Right-hand cutting geometry in laydown insert style
• 1/2 inch inscribed circle for compatibility with standard laydown threading toolholders
• BXC grade designation engineered for threading performance on a range of workpiece materials

Compatibility

Designed as a laydown-style threading insert for use in external UN thread turning toolholders accepting a 22 ER insert style with a 1/2 inch inscribed circle.

Installation Notes

Installation is performed by qualified machinists on CNC or manual turning equipment. Power down and lock out the machine before seating or replacing inserts. Use the correct torque wrench and insert clamp screw per the toolholder manufacturer specification to ensure proper seating. Verify thread form with a thread gauge after the first pass before committing to a full production run.
