Carmex 06IL18UNBXC Threading Insert 18 Tpi Left Hand Un

Product Description

The CARMEX 06IL18UNBXC is a laydown threading insert designed for cutting left-hand internal UN threads on CNC lathes and threading machines. Manufactured from solid carbide with a PVD-applied TiN coating, this insert delivers consistent thread form and extended tool life in demanding threading operations. It operates at 18 threads per inch (TPI) with a 5/32-inch (0.1563-inch) inscribed circle and a thickness of 0.073 inches. The BXC manufacturer grade designates the specific geometry and coating combination suited for internal threading applications where precision and surface finish are priorities for machinists and tooling specialists.

This insert is intended for internal UN thread profiles in metalworking and machining environments, including job shops, production facilities, and maintenance operations. The left-hand configuration makes it suitable for applications requiring reverse-threaded bores, such as specialty fastener systems and tooling fixtures. It is installed in compatible laydown threading toolholders designed for the 06IL insert style. Minimum order quantity for this insert is 10 pieces.

Key Features

• Solid carbide substrate for high wear resistance in threading operations
• PVD TiN coating reduces friction and extends insert life
• 18 TPI for UN internal thread form

• 5/32-inch inscribed circle (0.1563 inches) laydown style form factor
• BXC grade designation for precision threading performance

Compatibility

Designed for use in toolholders accepting the 06IL laydown threading insert style for internal UN thread applications.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine is fully powered down and the spindle is locked before seating or replacing inserts. Use the appropriate torx or clamping screw specified by the toolholder manufacturer to secure the insert without overtightening. Verify thread form and pitch against part specifications before running production cuts.
