ATORN TVC trochoidal end mill
milling tools for modern milling strategies

the new ATORN TVC end mills are ideally suited for processing various steels and
stainless steels/heat-resistant alloys using modern milling strategies. cutting
lengths of 3xD and 4xD, reinforced cores and specially developed chip breaker
geometries allow for deep operating depths with maximum process reliability.
the variable twist angles of 37°/38° and 41°/42° minimise vibrations
and optimise surface qualities.

maximum cutting edge lengths – both types are available in 3xD and 4xD
cutting length.
unequal twist angle
steel version = 37°/38°, stainless steel version = 41°/42°

edge protection chamfer – all tools are manufactured with a edge protection
chamfer against wear and tear.
chip breaker geometry – produces short chips, thus optimising
chip removal.
optimised number of teeth – 3xD tools have 5 teeth; the 4xD tools are manu-
factured with 4 teeth.
