Abstract (en)
A core-cutting tool (1), having a support body (3) having connection means (4), for connection to drive means. The tool has an annulus of cutting elements (2) arranged on one of its ends. The tool also has at least one abrasive element (5), arranged normal to the side wall of the tool and which does not extend radially beyond the outer edges of the annulus. When the core-cutting tool jams or snags during its operation, the tool is cut free by the abrasive element(s), thereby reducing the chances of accidents due to tool jamming. <IMAGE>
