Deburring knife for deburring even and uneven hole edges

Deburring tool according to claim through 8, wherein for replacement of the blade a movement is made in the direction of extraction and the central contact tongue of the spring glides along the right stop of the holding notch and is there diverted downward by spring deflection, by which it comes out of engagement with the holding notch.

Deburring tool for deburring straight or nonround hole edges with a base body driven rotationally around its longitudinal axis, in which one or more blades are replaceably accepted into a swivel-mounted blade holder in the base body, the blade holder having at least one control recess located on its circumference, in which a spring component engages, which guides the rotation of the blade holder in the base body, wherein for pivot bearing of the blade holder in the base body the blade holder has two drilled holes located across from one another on opposite sides of a mounting hole in the blade holder which receives the blade, into each of which the end of a bearing bolt engages, whose other end goes into a transverse hole in the base body and that one or more blades are thereby easily and replaceably mounted in the blade holder, at least one stop prevents axial displacement of the blade and one pullout safety device provides security in the axial direction for the blade,

• wherein the pullout safety device is in the form of a spring pin, which is flexibly mounted in a transverse hole in the blade holder and engages in a holding notch on the blade under spring pretension.

Deburring blade holder adapted to be pivotally mounted to and rotationally driven by a base body of a deburring tool, said blade holder further adapted to have at least one deburring blade removably mounted therein, said blade holder having at least one control recess located on a circumference of said blade holder, said control recess adapted to receive a spring therein to bias said blade holder to a deburring position, said blade holder having a mounting hole extending therein into which is received the deburring blade, said mounting hole configured so as to clamp the deburring blade in said blade holder.

Deburring blade holder adapted to be pivotally mounted to and rotationally driven by a base body of a deburring tool, said blade holder further adapted to have at least one deburring blade removably mounted therein, said blade holder having at least one control recess located on a circumference of said blade holder, said control recess adapted to receive a spring therein to bias said blade holder to a deburring position, said blade holder having a first mounting hole extending therein into which is received the deburring blade, said first mounting hole having a flexible clamping gap to clamp the deburring blade in said blade holder.
