The present invention provides a cutting tool assembly having a tool shank with an elongated hole extending axially through the tool shank. An elongated support bar having threaded bore at its forward end is retained in the elongated hole. A cutting head having a forward cutting portion and a rear threaded portion is retained in the support bar with its rear threaded portion threadingly engaged with the threaded bore in the forward end of the support bar.

A rectangular blade-type cutting tool having two edge-on cutting inserts mounted at one end of the blade in a staggered formation with their cutting edges partially overlapping. This type of cutting blade finds particular application in disc-type cutting tool assemblies used for cutting pipes. In such a cutting tool assembly the blade-type cutting tools in accordance with the present invention are equally peripherally distributed on an end face of the cutting tool assembly with the operative cutting edges of each of cutting blade inwardly directed and equally distanced with respect to the axis of rotation of the cutting tool assembly. With such a cutting tool assembly it is only necessary to cut the thickness of a pipe without the necessity of passing across its entire diameter allowing for quick and economical cutting of the pipe.

An apparatus is disclosed for cutting target material which includes a housing having an inner cavity and an elongated nozzle extending from the inner cavity to communicate with the exterior of the housing. The apparatus is provided with a charge for generating a cutting flame and an activating device coupled to the charge. A method for cutting target material is also provided in which the cutting apparatus has an elongated nozzle positioned generally adjacent to a surface of a target material to be cut. The cutting apparatus may be joined with one or more housings to provide a ganged together or joined cutting apparatus. The effect of this ganged cutting apparatus is to provide an extended linear cutting action on the surface of the target material. In addition, in an opposed cutting apparatus, two housings are positioned with their nozzle channels in opposition to permit cutting target material from two directions.

The present invention relates to a CVD-coated cutting tool insert with a TiC x N y -layer with a low tensile stress level of 10-300 MPa and an ±-Al 2 O 3 -layer with a high surface smoothness of <0.1 µm as measured by AFM-technique. This is obtained by subjecting the coating to a first intensive wet blasting operation with a slurry consisting of F80 grits of Al 2 O 3 followed by a second wet blasting treatment with a slurry of F320 grits of Al 2 O 3 .

The invention concerns a device (1) for manipulating tools comprising two parts, said device being of the type consisting of a frame and at least one tray forming a table, designed to receive the mold. The invention is characterized in that it comprises two horizontally arranged trays (6, 9-7, 8) one of which is arranged sliding on the frame to be mobile in translation relative to the other tray, from a close position to a remote position and inversely, so as to enable the tool to be manually opened and closed.

The invention concerns a device for the upkeep of a hedge (10) comprising an element adapted to move in reciprocating motion parallel above and/or beside the hedge (10). The displacement is performed repeatedly and automatically so as to prevent the hedge from growing beyond a predetermined limit by the trajectory of the mobile element. The mobile element is shaped like a gantry and moves along one or several aerial or ground rails (4). The ridges of the gantry are fitted with a cutting edge or with an abrasive element (6). The mobile element is driven by a roller (3) and is mounted on an electric gear motor (1).

The present invention relates to improvements in or relating to vegetation cutter apparatus. In particular, it relates to improvements in construction and manufacture of housings for lawn mowers. We describe a lawnmower having a deck with a lower surface defining a cutting chamber, a cutting element mounted within the cutting chamber, a motor assembly driving the cutter element, the motor being mounted on an upper surface of the deck, wherein the vegetation cutting apparatus further comprises a discharge chute having a discharge chute inlet in communication with the cutting chamber and a discharge chute outlet, a cover covering at least a portion of the motor assembly, and a pivotable deflector guard biased into a closed configuration against the discharge chute outlet. The discharge chute comprises a chute floor, chute sides and a chute roof. The present invention is characterised in that at least a portion of the chute roof is formed by a portion of the motor cover.

The device (1) comprises a base (2), carrying a servo motor (3) and attached to the frame of a machine center. A carriage (6) with a vertical shaft (8) on top can be moved on two telescopically arranged rails (4,5) joined horizontally to the base (2). The tool holding elements (16,17) are positioned at the upper end of the shaft (8) and can be fixed with a locking unit (18). A control plate (12) is located at the second rail (5) acting in combination with a guiding roll (10) in order to facilitate a swivel motion of the tool carrier (15).

The invention relates to a color chamber doctor blade 1 , which has following characteristic features: two doctor blade knives 2 that can be set up in a roof-like fashion against a roller 6 from which two doctor blade knives 2 can be fixed on the doctor blade chamber body 5 by means of a clamping plate 3 whereby the clamping plate 3 is in active connection with long-stretch fasteners 4 in the axial direction (z) of the roller 6, which are arranged essentially parallel to the clamping plate 3 and from which the force required for fixing at least one doctor blade knife 2 is applied. Inventive is that the resultant of the force exercised by the fasteners 4 points to the doctor blade chamber body 5.
