Emuge - 5/8-11 UNC 2B Modified Bottoming Thread Forming Tap

Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading to the bottom of blind holes and have 2 to 2-1/2 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.

Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
