Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
Vanadium High Speed Steel (HSSE) is made of high speed steel, carbon, vanadium carbide and other alloys to increase abrasive wear resistance and toughness. It is commonly used in general applications on stainless steels and high silicon aluminums.
Oxide, also known as black oxide or steam oxide, is a surface treatment that prevents chip building, galling and welding on the workpiece. It is commonly used on low carbons, stainless steel and ferrous metals.
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.
