Concept for the design of 3D models based on properties according to DIN 4000 - Part 81: Drills and counter sinking tools with non-indexable cutting edges
This standard is valid in conjunction with DIN 4003-1 and DIN 4000-81 and specifies the 3D-Modelling for drills and countersinking tools with non-detachable cutting edges. This standard is valid for standardized and not standardized drilling and countersinking tools with non-detachable cutting edges, which are directly applied to the main body and for tools with cutting edges which are fixed to the main body and mechanically non-detachable (e. g. brazed).
