Features and Benefits
Semi-bottoming chamfers are used for blind holes. They have 3 to 3-1/2 threads.
High Speed Steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
Titanium Aluminum Nitride (TiAlN) has a higher hardness and oxidation temperature versus TiN and TiCN. As a result, it is particularly advantageous for higher speed operations in a variety of steel machining applications.
