Abstract
A method and a device are disclosed for the production of a bore with a special shape, for example a bore which deviates from a cylindrical shape or a bore with an undercut. First, a first bore portion is produced using an oscillatingly driven tool, the first bore portion having a shape deviating from a cylinder and having at least one projection projecting from the wall face of the first bore portion towards the bore centre. Subsequently, when a bore with an undercut is to be produced, the tool is then at least partially rotated about its longitudinal axis, in order to produce a second bore portion which has a larger cross section than the first bore portion.
Claims20
A tool for producing bores having a shape deviating from a cylinder, said tool comprising:
- a shank having a first end and a second end, said first end being configured for chucking to an oscillatory drive;
- a cutting head located at said second end and having at least one projection radially protruding from said shank;
- and
- a cutting means provided on said cutting head.
A kit for producing bores having a shape deviating from a cylinder, said kit comprising:
- a drill;
- and
- a tool;
- wherein said tool comprises a shank having a first end and a second end, said first end being configured for chucking to an oscillatory drive;
- a cutting head located at said second end and having at least one projection radially protruding from said shank;
- and
- a cutting means provided on said cutting head.
A method for producing a bore, comprising the following step:
- (a) producing a first bore portion using an oscillatingly driven tool, said first bore portion having a shape deviating from a cylinder and having at least one projection projecting from a wall face of said first bore portion towards a centre of said bore.
