The Carmex Carbide Threading Insert – Unified – TiAlN Coated (14E18UN) is a versatile threading solution designed to cover the majority of common thread profiles with a single, durable carbide insert. Built for precision and reliability, it’s ideal for machine shops, job shops, and manufacturers seeking consistent results with fewer tool changes.

• Material: Carbide with a TiAlN coating for enhanced wear resistance and longer insert life in demanding threading operations.
• Thread Profiles Covered: Unified threading inserts that address all the common thread forms you encounter in metalworking.
• Length Options: Five lengths available, ranging from 12 mm to 40 mm to suit different depth requirements and tool geometries.
• Pitch Range: Supports pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI for broad compatibility with metric and imperial threads.
• Cutting Edges: Double-sided inserts with two cutting edges (except for BSPT / NPT / NPTF / American Buttress / API RD), maximizing usable life per insert.
• Internal/External Capability: In many thread profiles, the same insert can machine both internal and external threads (with exceptions for ISO / UN / NPSM / UNJ / Acme).
• Part Number: 14E18UN for precise ordering and replacement.

Designed to simplify tooling and reduce inventory, this unified carbide threading insert delivers dependable performance across a wide range of applications. Its TiAlN coating helps resist wear when cutting harder materials, while the double-edged design provides economical longevity. Use it for typical fasteners, fittings, and mechanical components where standard thread forms are required, and rely on consistent geometry to produce accurate threads with minimal setup.
