Solid carbide Thread mills Solid carbide thread mills are designed mainly for internal thread milling of small diameters in modern CNC machining centers. The solid thread mills have three or more spiral flutes which lead to shorter machining times, compared to tools that have only a single edge. A new, time saving, feature is the deburring edge that most of our solid thread mills are equipped with. The treading and deburring are made in one operation. The deburring solid thread mills are identified by the letter B in the cataloque number. All of our solid thread mills have 15° right hand...
