Product information for machine taps
The machine tap consists of heavy-duty high-speed steel. For through threads and bottoming
threads in unalloyed steels up to a strength of 800 N/mm², malleable.The thread is cut in one
operation.
High speed tool steel, best known as 'high speed steel', refers to a group of alloyed tool steels with
up to 2,06% carbon content and up to 30% proportion of alloying elements such as tungsten, mo-
lybdenum, vanadium, cobalt, nickel and titanium. HSS materials are characterised by great hard-
ness, wear resistance and heat resistance up to 600° C. The HSS tools are less sensitive to shocks
and vibrations, which sometimes quickly lead to breaks in the harder cutting materials.
The machine tap consists of cobalt alloyed heavy-duty high-speed steel. Its high heat resistance
means a longer tool life. For through threads and bottoming threads in unalloyed and alloyed
steels up to a strength of 1000 N/mm², malleable cast iron and non-ferrous metals. The thread is
cut in one operation.
Like high speed steel with cobalt alloy. This heat-resistant material is used for processing materi-
als with high strength and in long cutting channels with correspondingly strong heating. The cobalt
content of 5% provides a higher heat resistance and higher stressing capacity.

HSSE-Co 5 VAP for stainless steel
The machine tap consists of cobalt alloyed and vaporised heavy-duty high-speed steel.
For through threads and bottoming threads in unalloyed and alloyed steels up to a strength of
1000 N/mm², stainless steel. The thread is cut in one operation.
By "vaporisation" is meant the evaporation of a non-metallic oxide film. Vaporisation acts as a se-
parating layer and reduces the occurrence of cold welding. In cold welding there are workpiece
chips that build up on the flanks of the tap and damage the finished thread. Consequences of
cold welding are torn and dirty flanks. VAP improves the adhesion of lubricants to the tool surface.
