Carmex Carbide Threading Insert - ABUT - TiAlN Coated - 21-8ABUT

The Carmex Carbide Threading Insert ABUT with TiAlN coating is a versatile, high-precision tool designed for machinists who tackle a wide range of common thread profiles. Its ABUT geometry and robust carbide core deliver reliable performance across many threading tasks, even in demanding materials.

• Coating: TiAlN coating improves wear resistance and heat tolerance, helping maintain sharpness and extend tool life in demanding threading operations.
• Edge configuration: Double‑sided inserts provide two usable cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD, which are single-edged), maximizing uptime between indexings.
• Material: Carbide construction delivers rigidity and precision for consistent thread forms and cleaner finishes.
• Length range: Five lengths from 12 mm to 40 mm enable you to choose the right size for the job and support a broad range of pitches.
• Pitch capability: Suitable for pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), depending on the chosen length.
• Versatility across profiles: Designed to cover all common thread profiles with ABUT geometry, and in many cases the same insert can machine both internal and external threads.
• Compatibility notes: For ISO, UN, NPSM, UNJ, and Acme profiles, there are considerations around edge use and application; this insert family remains highly adaptable for a broad set of threading tasks.

This threading insert set helps streamline manufacturing workflows by reducing tool changes, delivering stable, accurate thread forms, and extending tool life through a hardened carbide core and TiAlN coating. It’s an ideal choice for machine shops and professionals who require dependable performance across a variety of standard thread types without juggling multiple dedicated tools.
