Features and Benefits

Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 threads.
Spiral point taps are used for tapping through holes. They have a flute geometry that shoots chips ahead of the cutting action to reduce loading and clogging within the flute.
NE2 is a proprietary nitride coating used for cutting a wide range of material including carbon steel, steel alloys, stainless steel, aluminum and copper. Ideal for short run tapping operations. NE2 is a proprietary coating exclusive to Emuge Corporation.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.

Features and Benefits

Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading blind holes and can be found with ranges between 2 to 2-1/2 threads. Some modified bottoming chamfers are 2-1/2 to 3 threads.
Nitride is a thin, hard-shell coating that supports surface hardness of the tool. It is commonly used where abrasive or wearing conditions exist.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
