摘要： A cutting tool assembly (10) includes a support block (12), a replaceable spray nozzle housing, a liquid seal tight insert ring and first and second fluid passages. The first fluid and second fluid passage has an axis and extends between the concealable outer surface portion (22) and a first (20) surface portion of the support block. The first and second fluid passages are substantially straight between first and second outer surfaces so as to permit a drill to be inserted into first and second fluid passage for cleaning. The cutting tool assembly (10) also includes an exterior replaceable spray nozzle housing (14) on the support block having a cylindrical inlet portion (38) that extends into the first fluid passage such that the spray nozzle housing (14) is in fluid communication with the first fluid passage. A separate insert ring independent of a tool holding wear protective sleeve is press fit into the rear portion of the support block and forms an annular flow chamber section of the first fluid passage. The insert ring may be readily removed in the field to permit cleaning of the first fluid passage.

摘要： The invention relates to a device for detachably fixing a rounded-shaft tool (5) into a tool bushing which is fixed into a tool holder (1) so that it can be detached. In said device, the interior sleeve of the bushing (10) has an annular groove, into which an elastic fixing ring (13) engages that is located in an annular groove (12) of the tool shaft (11). The device is characterised in that the elastic fixing ring (13) is configured as a slotted, plastic ring which has a rib (16) running around its periphery and that the width of the annular groove (17) on the interior sleeve of the bushing, when measured in an axial direction, is greater than the width of the rib (16) which runs around the periphery of the elastic plastic ring and extends into said annular groove (17). In addition, the front face (18) of the ring rib (16) which faces the tool tip is positioned parallel to the front face of the annular groove (17) on the interior sleeve of the bushing (10), pointing towards said front face of the ring rib.

摘要： The invention relates to a nozzle device for equipping chisel bits (13) of a holing machine in which the chisel bits are configured as round shank chisel bits (13) having a hard material or hard metal insert. The nozzles (19) are oriented in the direction of the cutting path, whereby water is supplied over a part of the rotation of the cutting heads (11) or cutting rollers by means of a sector control. In order to decrease the wear of the hard metal or hard material inserts, the invention provides that the axes (22) of the nozzles (19) are arranged such that they are sloped toward the chisel bit tips (23) and toward the cutting path. In addition, the sector control is adjusted in such a way that the nozzles (19) are actuated with pressurized water over an angle ranging from at least 45 DEG , preferably between 65 DEG and 85 DEG , of the rotation of the cutting head (11) or of the cutting roller after the chisel bit (13) exits the rock. The nozzles (19) are actuated by a pressure exceeding 50 bar.
