World's Most Comprehensive Range of Carbide Threading Inserts

GMT Cutting Tools

Largest cemented carbide manufacturers

A Standard Range

GMT the World's Most Comprehensive Range of Carbide Threading Inserts. None of the large cemented carbide manufacturers have anywhere near the same range as that available from GMT. The reason is simple. Threading is a fairly small part of all machining operations, and has been neglected by major carbide companies who offer only a limited range of the most common profiles.

On the other hand GMT has a range that covers all of the threads used throughout the world. The main product range is concentrated on inserts and toolholders for threading. In simpe terms, GMT is a specialist.


Few manufacturers can offer threading inserts with sintered-in-chipbreakers. But GMT can. The advantage of sintered-in chipbreakers is that a greater freedom is available in designing the chipbreaker geometry. And the opportunities suddenly open up for producing the optimum chipbreaker form even on threading inserts.

Full-profile Inserts for the Perfect Thread

The GMT full-profile insert has the entire thread profile formed in the insert in accordance with standard specifications. And since the insert has the complete profile, the thread produced will be perfectly formed , concentric and free from burrs.
