The Carmex Carbide Threading Insert ABUT TiAlN Coated (model 30-16ABUT) is a versatile threading solution designed for machinists and production shops needing reliable performance across a wide range of common thread profiles.

• Five length options: available in lengths from 12 mm to 40 mm to fit diverse toolholders and applications.
• Wide pitch compatibility: capable of handling pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for versatile threading tasks.
• Double-sided cutting edges: inserts are typically double sided, providing two usable edges per insert to extend life (with specific exclusions for BSPT/NPT/NPTF/American Buttress/API RD).
• Internal & external threading capability: for many thread profiles, the same insert can machine both internal and external threads, improving versatility (excluding ISO/UN/NPSM/UNJ/Acme).
• TiAlN coating: TiAlN coating enhances wear resistance and heat management, helping maintain edge life on demanding materials.
• ABUT geometry: designed to cover a broad range of common thread forms with a single, efficient insert approach.

This threading insert delivers practical value on the shop floor: you gain flexibility to tackle multiple thread geometries without swapping tooling, a longer edge life thanks to the TiAlN coating, and fewer insert changes thanks to the dual-cutting-edge design. It’s an ideal choice for workshops that regularly produce both internal and external threads across steel, stainless, and alloy components, while maintaining predictable performance and finish quality.
