摘要：
The invention concerns a drilling tool consisting of a tool head (3) and a tool shank (5) comprising at least one chip groove. A slotted sleeve (10) is placed on the tool shank and closely surrounds said chip groove, the edges (14, 15) adjacent the slot (13) lying on solid material of the tool shank (5). The chip grooves (7) and the sleeve (10) form channels for carrying away the chips removed at the workpiece machining base. Owing to the slot (13), the sleeve (10) can be gently spread apart and pushed onto the tool shank (5) from the end comprising the enlarged tool head (3).
