Carmex Carbide Threading Insert in UNJ size delivers durable, precise threading performance for engineers and machinists working with UNJ profiles. With a TiAlN coating and a versatile edge design, this insert is built to handle a range of common thread profiles in demanding manufacturing environments.

• Profile: UNJ threading insert designed to tackle UNJ thread applications with reliable precision.
• Coating: TiAlN-coated carbide for enhanced wear resistance and heat tolerance during cutting.
• Material: Solid carbide construction for rigidity and long-edge life under demanding cutting conditions.
• Lengths: Five available lengths from 12 mm to 40 mm to suit different tooling setups and workpiece geometries.
• Pitch range: Compatible with pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI, depending on the chosen length.
• Double-sided edges: Inserts are double-sided with two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), maximizing use before index.
• Internal/External versatility: For many thread profiles, the same insert can machine both internal and external threads, with exceptions for ISO / UN / NPSM / UNJ / Acme.

This insert is designed to simplify threading workflows: rotate to use a fresh edge, reduce tool changes, and maintain consistent thread quality across a range of profile standards. The TiAlN coating helps extend tool life when machining harder materials, while the five length options let you tailor the insert to your machine spindle and workpiece geometry. Ideal for precision components and assemblies that require robust UNJ threading with dependable performance.
