Carmex Carbide Threading Insert, Unified, TiAlN Coated, 30E12UN is a versatile threading solution designed for machinists who need broad-profile capability in a single insert family.

• Coating: TiAlN coating provides enhanced hardness and heat resistance for longer tool life and steadier cutting at higher speeds.
• Profile coverage: Unified threading insert system that covers all common thread profiles with a single family, reducing the need for multiple inserts.
• Lengths: Five available lengths from 12 mm to 40 mm to suit different depths and machine setups.
• Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI) for broad application versatility.
• Double‑edged design: Each insert is double-sided with two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD variants), maximizing usage between index changes.
• Internal/External compatibility: For many thread profiles, the same insert can machine both internal and external threads (except ISO/UN/NPSM/UNJ/Acme).
• Material: Carbide construction delivers rigidity and consistent performance across a range of materials and applications.
• Designation: 30E12UN, aligned with Unified thread standards for common, general-purpose threading tasks.

This threading insert is ideal for mechanical assemblies, housings, adapters, and pipe fittings where a single, reliable tool can cover multiple thread profiles. The TiAlN coating helps you maintain productivity by enabling higher speeds and reducing wear, while the range of lengths and the dual cutting edges mean fewer tool changes and more efficient setups. Whether you’re threading steel, aluminum, or other common machinable metals, this Carmex unified insert is designed to deliver precise, repeatable results across a variety of standard thread forms.
