An all-purpose carbide threading insert set designed for unified thread profiles. It offers reliable performance across common threads with a TiAlN coating for enhanced wear resistance, making it ideal for professional machinists and production shops.

• Coating: TiAlN-coated carbide for improved heat resistance and longer edge life in demanding threading jobs.
• Thread profiles covered: Versatile inserts that support the majority of common unified threading profiles, reducing the need for multiple tool types.
• Length options: Five lengths available (from 12 mm to 40 mm) to match different thread pitches and machining setups.
• Cutting edges: Double-sided design with two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles) for extended tool life.
• Internal and external threading: For many thread profiles, the same insert can machine both internal and external threads, simplifying tooling (with certain profile exceptions such as ISO/UN/NPSM/UNJ/Acme).
• Pitch range: Handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), covering a wide range of standard thread sizes.
• Brand and series: Carmex Carbide Threading Insert – Unified series (model 30I8UN), designed for compatibility with unified threading operations.

This threading insert set is designed to streamline your workshop workflow. The combination of carbide hardness and TiAlN coating delivers durable performance on typical metals, while the dual-cutting-edge design reduces downtime by letting you flip the insert for extended use. Its broad profile coverage and multiple length options make it a practical choice for shops performing a variety of unified-thread applications, from quick prototyping to production runs.
