Features and Benefits
Taper chamfers also known as starter taps have a longer chamfer and require a less aggressive cutting action. They have 7 to 10 threads.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
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.
