1599 7/16-20 H3 4FL HSS BOTT HAND TAP

For through or blind hole applications

• Designed for through or blind hole tapping with a specific cutting geometry for gray cast irons and those materials producing broken chips
• Also ideal for non-metallics, cast brass and other brass materials producing broken powdery chips
• Nitride and steam oxide coating reduces wear and chip welding in abrasive materials
• Nitriding is a process that is used to increase the hardness and wear resistance of the surface of a tool
• It is particularly suitable for taps that are used on abrasive materials such as cast iron, bakelite
• Nitriding is used on twist drills when it is desirable to increase the strength and wear resistance of the cylindrical lands
• Steam tempering gives a strongly adhering blue oxide surface that acts to retain cutting fluid and prevent chip to tool welding, thereby counteracting the formation of a built-up edge
• Steam tempering can be applied to any bright tool but is most effective on drills and taps
• A medium alloyed high speed steel that has good machinability and good performance
• HSS exhibits hardness, toughness and wear resistance characteristics that make it attractive in a wide range of applications
