Features and Benefits
Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.
Titanium Nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials. The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools.
Vanadium High Speed Steel (HSSE) is made of high speed steel, carbon, vanadium carbide and other alloys to increase abrasive wear resistance and toughness. It is commonly used in general applications on stainless steels and high silicon aluminums.
