Emuge - M22x2.50 Metric 6H 0 Flute TiN Finish Cobalt Machine Tap

Modified bottoming is similar to bottoming, but the chamfer is longer and has more teeth. They are used for threading blind holes and have 2 to 2-1/2 threads.

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

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.
