Abstract
An apparatus for removing burrs in confined spaces of molds or cores is disclosed. The apparatus includes a retaining body; and at least one deburring element resiliently mounted in an unloaded state on an outer circumference of the retaining body. The at least one deburring element has a ring containing a separating point. The separating point is inclined to a longitudinal axis of the retaining body at an angle of 45.degree.. Alternatively, in accordance with the invention, at least one deburring element is resiliently mounted in an unloaded state on an outer circumference of the retaining body. Each deburring element has a deburring portion projecting radially outward from a remainder of the deburring element for removing the burrs and is retained in the outer circumference to be axially displaceable with the retaining body in a first axial direction and in a second axial direction opposite to the first axial direction. Each deburring element is displaceable radially inward during motion of the retaining body in the first axial direction and displaced radially outward during axial motion of the retaining body in the second axial direction.
