Emuge - M3.5x0.60 Metric 6H 3 Flute TiN Finish Cobalt Spiral Point Tap

Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 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.
