Carmex 11IR36UNBXC Threading Insert 36 Tpi 1/4 Inch Un

Product Description

The CARMEX 11IR36UNBXC is a solid carbide laydown threading insert designed for internal UN thread cutting at 36 threads per inch. This right-hand insert fits standard laydown-style toolholders and is used in CNC lathes and turning centers to produce precise internal threads. It features a PVD-applied TiN coating for improved wear resistance and longer tool life. The insert measures 0.25 inches inscribed circle diameter and 0.1270 inches thick, conforming to the 11IR form factor. It is suited for production threading in ferrous and non-ferrous materials where consistent thread geometry and surface finish are required.

This insert is used in CNC turning operations requiring internal UN-standard threads at 36 TPI. Typical applications include threading bores in hydraulic fittings, fastener components, and precision machined parts. The right-hand cutting geometry makes it compatible with conventional right-hand boring bar setups. Machinists and CNC operators in production shops, job shops, and maintenance machining environments install this insert when tight thread tolerances and repeatable results are needed. The BXC grade designation reflects the manufacturer-specified carbide substrate and coating combination for this application range.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading applications
• TiN coating applied via PVD process for extended edge life and reduced built-up edge
• 36 TPI cutting geometry for UN internal thread standard
• Right-hand cutting orientation for conventional boring bar setups
• 11IR laydown form factor for compatibility with standard laydown-style threading toolholders
• 1/4 inch (0.25 inches) inscribed circle with 0.1270 inch thickness for precise seating

Compatibility

Designed as an OEM-style replacement or production threading insert for standard 11IR laydown threading toolholders used in internal UN thread applications at 36 TPI.

Installation Notes

Installation is performed by machinists or CNC operators on lathes and turning centers. The machine spindle must be stopped and the toolholder secured before changing inserts. Use a torx or hex key as specified by the toolholder manufacturer to clamp the insert at the correct seating force. Verify insert seating is flush and secure before resuming cutting operations to avoid thread form deviation or insert breakage.
