The Carmex Carbide Threading Insert - Unified - TiAlN Coated - 40I8UN is a versatile, high-performance threading solution engineered for machinists who demand reliable results across the most common Unified thread profiles.

• Length options: Five lengths spanning 12 mm to 40 mm to fit a wide range of toolholders and workpiece depths.
• Thread pitch range: Handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), covering both fine and coarse thread applications.
• Double-sided cutting edges: Each insert provides two cutting edges for extended usage before indexing (except for BSPT/NPT/NPTF/American Buttress/API RD profiles).
• Internal & external capability: For many thread profiles, the same insert can machine both internal and external threads, simplifying setup (note exceptions apply for ISO/UN/NPSM/UNJ/Acme).
• Coating & material: TiAlN coating on a carbide substrate delivers improved hardness, wear resistance, and heat tolerance for higher-speed threading and longer tool life.
• Comprehensive coverage: Designed to cover all common thread profiles, reducing the need for multiple dedicated inserts in everyday production.

This threading insert set is ideal for job shops and manufacturing environments where reliability and efficiency matter. The TiAlN-coated carbide construction provides durability under demanding cutting conditions, while the five-length assortment and wide pitch range enable you to tackle a broad spectrum of Unified thread tasks with a single, cohesive solution. The dual-edge design helps maximize uptime by enabling quick edge changes, and the internal/external threading capability (where applicable) streamlines workflows and spare-parts inventory.
