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).

摘要:
The invention concerns a device for machining of work pieces (76) or objects, comprising an elongated tool (10) which rotates about its longitudinal axis and is provided with a shaft (14) which can be coupled to a drive unit (48) and with a chip-removing head (16) connected to the shaft (14). In order to ensure that even a very long tool can be used in deep hollows in the work piece in a stable and vibration-free way, the invention proposes a sleeve (20) between the shaft (14) and the chip-removing head (16), connected at one end to the chip-removing head (16) in such a way that it cannot slide or rotate. The tool can be clamped in the chuck of a hand-held drive unit, preferably with a suction and flushing device (50) connected in series and used to suck away chips through the cavity in the sleeve (20) and to pump cooling fluid onto the cutting site (44).
