The Carmex Whitworth Carbide Threading Insert with TiAlN coating is a versatile carbide solution designed for machinists who regularly produce threaded components. It supports Whitworth and other common thread profiles, delivering consistent performance across both internal and external threads with a single, durable insert.

• TiAlN coating: TiAlN-coated carbide for enhanced wear resistance and reduced friction at higher cutting speeds.
• Thread profile versatility: Covers Whitworth and other common thread forms, making it suitable for a wide range of turning and threading tasks.
• Five length options: Five lengths spanning from 12 mm to 40 mm to accommodate different depths and pitches.
• Double-sided cutting edges: Two cutting edges per insert (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), increasing usable life per insert.
• Internal & external threading: For many profiles, the same insert can machine both internal and external threads (except ISO/UN/NPSM/UNJ/Acme).
• Pitch range compatibility: Able to handle pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), depending on the chosen length.

This insert is ideal for shops that prioritize efficiency and consistency in threaded components. By combining multiple common thread forms into a single, robust carbide insert, it reduces tool changes and stocking needs while delivering reliable thread quality. The TiAlN coating helps maintain tool life under demanding conditions, and the dual cutting edges extend usage between resharpening or replacements. Use cases range from general-purpose Whitworth threading on home or production machines to broader applications that require quick switching between internal and external threads without swapping inserts.
