Abstract: A rock drill bit for percussive drilling, especially top hammer drilling, includes a drill head provided with rock removing members. The rock drill bit is provided with a number of external grooves for conducting cuttings, the grooves extending in the axial direction of the rock drill bit. Formed between adjacent grooves are lands which also extend in the axial direction of the rock drill bit. The rock drill bit has a thread for connection of the rock drill bit to a drill rod. Rear end portions of at least some of the lands define retrac teeth. Each retrac tooth has at least one cutting edge. At least some of the lands comprise a chip surface and a clearance surface that form therebetween an edge angle not greater than 100null.

Abstract: A new method and apparatus for manufacturing powders of cemented carbide, cermets, ceramics and similar materials with good abrasive wear resistance starting from a slurry, wherein the slurry is introduced into a drop forming device including at least one essentially horizontal oriented rotating drop forming disk (12), from which the drops are slung out to solidify by centrifugal force. According to the invention the slurry is ejected from a discharge opening (21) on the drop former in the form of a jet such that it hits a first obliquely downward and inwardly directed surface (22) whereby the speed of rotation of the disk is chosen such that the jet of liquid is forced upwards over the first surface as well as over to another connected horizontal surface (23) and thereafter is ejected as a split jet against a second obliquely downwards-outwards directed surface (25) such that the slurry is accelerated to the speed of the drop forming disk (12) and then is led over a third surface (26) obliquely directed outwards, from where the drops are then caused to detach themselves and fall down, thus forming a powder.

Abstract: A drilling tool set includes a plurality of drilling tools having different operative drill diameters to blast drill holes of different respective diameters. Each drilling tool of the set has a basic body defining a central axis of rotation, and two replaceable indexable bits including a center bit and a periphery bit which are mountable in respective center and periphery pockets formed in a front end of the basic body. The periphery bits of the respective drill tools of the set are identical, and the center bits of the respective drill tools of the set are identical. Each of the center and periphery pockets of each drill tool defines a radial center point. A first of the drill tools has a smaller operative drill diameter than a second of the drill tools. The first tool includes a first periphery pocket and a center pocket. The center point of the first periphery pocket is disposed closer to the axis than is the center point of the second periphery pocket. The center point of the first center pocket is disposed closer to the axis than is the center point of the second center pocket.
