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.
