Abstract
The invention relates to a method for the production and/or the re-tipping of a diamond-core bit in a tubular form, the end face 3 of which has a greater wall thickness than the rest of the tubular wall in order to carry cutting segments 2 on the annular end face 3, the greater wall thickness in the tubular end area 3, 4 being obtained by upsetting, in particular in a rolling process. <IMAGE>
