Abstract

The hollow drilling tool consisting of a tubular support body (1) and cutting segments (2) let into receptacles (1a) at the front end of the support body is provided with predetermined breaking points between the individual cutting segments (2), which predetermined breaking points run in a U-shape, are open towards the front end and are formed by cross-sectional reductions. The predetermined breaking points, formed as recesses (1b, 1c), enable slots (1d) to be broken out for the passage of the cooling water. <IMAGE>
