Abstract
A deburring tool () for deburring of edges of transverse recesses (-), which diverge from a main borehole (), consisting of a shaft () driven to turn about the tool axis (), which is deployable and retractable in the forward feed direction into the main borehole, and on the lower end of which at least one knife window () is arranged, in which at least one spring-loaded knife (″″) is arranged roughly perpendicular to the tool axis (), so as to be shiftable, which on its front end has at least one cutting edge () which encounters the edge of the transverse recess (-), and deburrs same, wherein the knife (″″) consists of two cutting edges () opposite in the rotational direction (), which act to cut equally for the right and left passes (), with one cutting edge () being configured to cut for the rightward pass (), both in forward motion () and in rearward motion, and the other cutting edge (), being configured to cut for the leftward pass (), both in forward motion () and in rearward motion, and that the two cutters () with their cutting edges are placed at a slant and with arch shape at an angle between 0° and 90°, but preferably between 5° and 45° to the tool axis () and thus to the longitudinal axis () of the main borehole ().
