Carmex Carbide Threading Insert - Whitworth - TiAlN Coated - 21-19W

The Carmex Carbide Threading Insert for Whitworth threads is a TiAlN-coated carbide tool designed to deliver precise, reliable threading across a wide range of profiles. Built for professional shops that demand durability and efficiency, it simplifies setup and boosts productivity in everyday turning and threading tasks.

• Thread profiles covered: A versatile collection of inserts that span all common thread profiles, reducing the need for multiple tools.
• Length options: Five lengths available from 12 mm to 40 mm to fit different part sizes and threading depths.
• Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Double-sided cutting edges: Each insert provides two cutting edges for extended life (except for BSPT/NPT/NPTF/American Buttress/API RD variants).
• Internal/External capability: For many profiles, the same insert can machine both internal and external threads (with exceptions ISO/UN/NPSM/UNJ/Acme).
• Coating: TiAlN coating enhances hardness and wear resistance, helping maintain thread quality and extend tool life in demanding materials.

This insert is designed to deliver consistent, accurate Whitworth threading across a variety of applications. The TiAlN coating reduces wear under high-speed conditions, while the double-edged design maximizes usage before reindexing. Its broad profile coverage and compatibility with both internal and external threading tasks make it a practical choice for production runs and precision work alike, helping you keep setups short and results repeatable.
