The Carmex Carbide Threading Insert with TiAlN coating is a durable, high-precision tool tailored for NPSM and other common thread profiles. Built for professional workshops and serious hobbyists alike, it delivers reliable performance across a range of threading tasks.

• Thread profiles covered: Broad support for common threading standards, including NPSM, enabling efficient work on multiple projects with a single insert.
• Material: Carbide base with a TiAlN coating for exceptional hardness, wear resistance, and heat tolerance in demanding cutting conditions.
• Coating: TiAlN provides extended edge life and better performance on harder metals and higher-speed machining.
• Length options: Five lengths available, ranging from 12 mm to 40 mm to fit different hole depths and cutting setups.
• Pitch range: Supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), with capability depending on the chosen length.
• Edge design: Double-sided design offers two cutting edges (where applicable), allowing more use per insert before indexing.
• Internal vs external capability: In many thread profiles, the same insert can machine both internal and external threads, with exceptions for ISO, UN, NPSM, UNJ, and Acme standards.

This insert helps you achieve consistent thread quality with fewer tool changes and longer service life thanks to its carbide substrate and TiAlN coating. The precise geometry and durable coating minimize heat build-up and wear, delivering clean, accurate threads on a variety of materials. Ideal for CNC lathes and precision turning applications, it supports efficient production workflows and dependable results on NPSM and other common thread profiles.
