Lone Star Carbide & Tooling stocks a wide variety of API and Semi Premium threading inserts to support the OCTG community around Houston, TX and abroad.

There is no minimum purchase and we keep specific items in stock based on our customer’s needs.

Premium Threading Inserts

Lone Star Carbide & Tooling is licensed to manufacture premium inserts for various companies in the oil and gas industry. We have also worked with their R&D department to create inserts for new thread forms and provide overlays.

Carbide Substrate & Coating Grades

There is never a “one size fits all” when it comes to threading inserts. Things like the grade of the steel pipe, programming, RPM and depth of cut all come into play when figuring out which carbide substrate and coating combination will work best for our customers.

Knowing what the inserts will be cutting as well as machining parameters helps us determine which carbide substrate and coating will work best for that application.

Research & Development

Lone Star Carbide & Tooling provides its customers with personal start to finish R&D turning a customer’s new thread form into an threading tool. With decades of experience in designing inserts, we will advise our customers to make the best tool for their application. Depending on threading material and programming we can suggest the most appropriate substrate and coating combination.
