Carmex Carbide Threading Insert - Whitworth - TiAlN Coated - 21-11W

Introducing the Carmex Carbide Threading Insert - Whitworth - TiAlN Coated (21-11W): a durable, versatile carbide insert built for precision Whitworth threading and a broad range of common thread profiles. Designed for machinists and workshops that demand reliable performance in threading operations.

• TiAlN coating: TiAlN coating enhances wear resistance and heat tolerance for longer tool life in demanding threading tasks.
• Carbide material: Premium carbide construction delivers rigidity, accuracy, and smooth cuts for Whitworth and other standard thread profiles.
• Five length options: Available in five lengths (12 mm to 40 mm) to fit different machines and thread engagements.
• Pitch range compatibility: Handles pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), depending on the chosen length.
• Double-sided cutting edges: Each insert provides two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD) to maximize usable life.
• Internal/External capability: In many profiles, the same insert can machine both internal and external threads (except ISO/UN/NPSM/UNJ/Acme).
• Whitworth-focused: Specifically optimized to produce accurate Whitworth thread forms with clean finishes.

This insert is designed to reduce tool changes and streamline setup by covering a wide range of thread profiles with a single, reliable solution. The TiAlN coating and carbide construction work together to deliver consistent performance, while the dual-edge design and broad pitch compatibility support efficient, high-quality threading across jobs. Ideal for precision threading in workshops and production environments where durability and accuracy matter.
