Thread turning is a machining process that involves cutting threads onto a workpiece using a lathe or CNC machine. This process allows for the creation of precise internal and external threads on a wide variety of materials, including steel, stainless steel, titanium, and non-ferrous metals.

On this page, you’ll find a comprehensive range of thread turning inserts designed for every threading application. These high-quality inserts, often made from solid carbide, offer excellent wear resistance, durability, and precision. Available in multiple geometries—full profile, partial profile, and specialized designs—our inserts provide the versatility needed for any threading project.

While taps and threading dies are also used in thread cutting, threading inserts offer distinct advantages:

  • Exceptional Precision and Accuracy: Each insert is engineered to provide consistent thread size and location, ideal for industries requiring exact tolerances, such as aerospace, medical, and manufacturing.
  • Versatility: Our selection covers Metric, BSW, UN, NPT, ACME, and specialty thread forms, ensuring you can handle virtually any application with the right insert.
  • Superior Surface Finish: Thread turning inserts deliver smooth, controlled cuts for a superior surface finish on both internal and external threads.
  • Enhanced Productivity: One insert can often perform multiple threading tasks, saving time and simplifying your workflow.
  • Durability and Longevity: Made from premium materials, these inserts withstand high cutting loads and maintain a sharp edge longer than traditional tools, reducing downtime and costs.

Explore our full range of threading inserts below to find the perfect solution for your machining needs. Whether you need internal or external threads, full profile, partial profile, or specialized threads, our selection provides the precision, flexibility, and durability required for high-quality thread turning.
