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 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.
MolyGlide is a non-stick, low friction coating that has good sliding properties. It is commonly used for dry applications or where lubrication is minimal. MolyGlide is a proprietary coating exclusive to Guhring, Inc.
Fast Spiral Flutes with 40-53 degree angles are suitable for ductile materials like aluminum and copper; medium to high carbon steels and free machining stainless steels.
