Carmex Carbide Threading Insert – ABUT – TiAlN coated (30-4ABUT) is a versatile threading solution designed for professionals who need reliable performance across a broad range of common thread profiles. engineered for durability and consistency, it supports diverse threading tasks with a single insert family.

• Coating: TiAlN coating enhances wear resistance and extends tool life in demanding threading applications.
• Lengths: Available in five lengths, from 12 mm to 40 mm, to fit a variety of hole sizes and toolholders.
• Pitch range: Supports 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-edged for two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), maximizing usable life.
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external threads (with exceptions ISO/UN/NPSM/UNJ/Acme).

This design translates into practical benefits: fewer tool changes thanks to dual cutting edges, broad compatibility across standard thread forms, and extended life from the TiAlN coating. The five length options let you optimize setups on CNC lathes or manual machines, while the broad pitch range covers everything from fine to coarse threads. In short, it delivers dependable, versatile threading performance with a streamlined toolkit.
