Abstract
The present invention relates to a tool and a metal tip of the tool. The tool includes a tool blank, a bearing portion and a metal tip where the tool is intended to be rotatably mounted in a road planing cutter. The longitudinal axis of the tool forms, in active position, an angle V in the interval 20.degree.-90.degree. relative to the road surface. The metal tip includes a portion for attachment to the tool blank and a cylindrical or slightly conical portion that is connected to a shape-defining surface located at the opposite end of the metal tip in relation to the attachment portion. The metal tip is mounted in the tool and contacts the road surface in the active position. The metal tip has a sharp edge in the transition between the cylindrical or slightly conical portion and the shape-defining surface.
Claims20
A road planing tool including a tool blank, a bearing portion disposed at a rear end of said tool blank and a metal tip disposed at a front end of said tool blank, said bearing portion configured to be freely rotatably mounted in a road planing apparatus with said metal tip contacting the road surface, a longitudinal axis of said tool forming, in an operative position of the road planing apparatus, an angle in the interval 20.degree.-90.degree. relative to a road surface, said metal tip including a rear end surface attached to said front end of said tool blank and having one of a cylindrical or slightly conical portion extending forwardly from said rear end surface to a front end surface of said metal tip, the metal tip having a sharp circular cutting edge in the transition between said front end surface and said one of the cylindrical or slightly conical portion.
A road planing cutter tip intended to be connected to a tool blank for creating a rotatable tool for mounting in a road planing apparatus, said tip being formed of metal and including a rear attachment portion for attachment to the tool blank, said tip having one of a cylindrical and slightly conical portion extending between said rear attachment portion and said front end surface of said metal tip, the metal tip having a sharp circular cutting edge in the transition between said front end surface and said one of the cylindrical and slightly conical portion.
Method for working road surfaces, using a plurality of tools, comprising the steps of rotatably mounting the plurality of tools on a road planing vehicle, each of said tools having a metal tip with a sharp circular cutting edge at a free end thereof, contacting the road surface with the metal tips of the tools, and advancing the vehicle such that the metal tips work the road surface by a rolling, cutting working action of the sharp cutting edges of the metal tips.
