Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
High Speed Steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
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.
