Abstract
In order to ensure highly precise setting, in particular readjustment of the radial position of the blade in the case of a rotary tool, in particular a reamer, an adjustment element, in particular in the form of an adjustment screw, having a cone formed by the screw head is inserted into an end-side receptacle in a cutting section, said cone being provided with a friction-reducing coating.
Claims19
1-9. (canceled)
A rotary tool, comprising:
- a cutting section extending along a center longitudinal axis, said cutting section having at least one blade on its circumference;
- and
- an adjustment element having a cone that is inserted into an end-side receptacle in the cutting section in order to set the radial position of the at least one blade, said adjustment element being displaceable in the direction of the center longitudinal axis in order to radially widen the cutting section,
- wherein the cone or the receptacle is provided with a friction-reducing coating.

A reaming tool, comprising:
- a cutting section extending along a center longitudinal axis, said cutting section having at least one blade on its circumference;
- and
- an adjustment element having a cone that is inserted into an end-side receptacle in the cutting section in order to set the radial position of the at least one blade, said adjustment element being displaceable in the direction of the center longitudinal axis in order to radially widen the cutting section,
- wherein the cone or the receptacle is provided with a friction-reducing coating.
1 more element
A rotary tool, comprising:
- a cutting section extending along a center longitudinal axis, said cutting section having at least one blade on its circumference;
- and
- an adjustment element having a cone that is inserted into an end-side receptacle in the cutting section in order to set the radial position of the at least one blade, said adjustment element being displaceable in the direction of the center longitudinal axis in order to radially widen the cutting section,
- wherein a stop surface oriented perpendicularly to the center longitudinal axis is formed on the adjustment element and a corresponding counter-stop surface is formed on the receptacle, said stop surface and said counter-stop surface limiting the axial adjustment movability of the adjustment element such that a radial expansion limit of the receptacle is not exceeded,
- wherein during the adjustment movement the cone rotates with respect to the receptacle about the center longitudinal axis,
- wherein the cone has an outer bevel on its end remote from the receptacle,
- wherein the adjustment element has on its opposite end sides and coaxially with its center longitudinal axis central guide receptacles each having a centering bevel.
