DRILLING TOOL

The invention relates to a drilling tool, in particular a rock drilling tool, for a portable machine tool, comprising a rotational axis (12a; 12b; 12c; 2d) and at least one spiral path (14a; 14b; 14c;14d), which is coiled about the axis of rotation (12a; 12b;12c; 12d) along the axis of rotation (12a...

More Information
Summary:The invention relates to a drilling tool, in particular a rock drilling tool, for a portable machine tool, comprising a rotational axis (12a; 12b; 12c; 2d) and at least one spiral path (14a; 14b; 14c;14d), which is coiled about the axis of rotation (12a; 12b;12c; 12d) along the axis of rotation (12a; 12b;12c; 12d), wherein the spiral path (14a; 14b; 14c; 14d) has at least one wear surface (16a; 6b; 16c; 16d). According to the invention, the drilling tool has at least one wear surface transition (18a; 18b; 18c; 18d), in which position there is a change in at least one bandwidth (20a; 20b; 20c;20d) of the wear surface (16a; 16b; 16c; 16d). 本发明涉及种用于便携式工具机的钻孔工具、尤其凿岩工具，所述钻孔工具具有旋转轴线(12a；12b；12c；12d)并且具有至少个沿着所述旋转轴线(12a；12b；12c；12d)绕着所述旋转轴线(12a；12b；12c；12d)盘绕的螺旋路径(14a；14b；14c；14d)，其中，所述螺旋路径(14a；14b；14c；14d)具有至少个磨损面(16a；16b；16c；16d)。提出，所述钻孔工具具有至少个磨损面过渡部(18a；18b；18c；18d)，所述磨损面(16a；16b；16c；16d)的至少个带宽(20a；20b；20c；20d)在所述磨损面过渡部的位置处改变。
