A deburring tool with a deburring blade () for deburring borehole edges () that have a straight or un-round shape, consisting of a base body () which is rotatably driven about its longitudinal axis (), and at the lower end of which at least one blade holder () with at least one deburring blade () secured therein is mounted on a blade bearing () on the side of the base body so as to swivel vertically, and on the outer periphery of the blade holder () a control groove () which is open radially outward is arranged, into which the freely flexible end () of a flexible spring () engages, the other end of said spring being clamped to the base body (), wherein during the deburring process, the deburring blade () is swiveled away from the base body () at an angle () in relation to the longitudinal axis of the base body (), and the blade axis () of the deburring blade () rests, spring-loaded, with its at least one cutting edge () against the borehole edge () to be deburred, and executes spring-loaded swiveling movements that follow the contour of the borehole edge () as the deburring tool is rotated, wherein the blade axis () of the deburring blade (), in the home position in which it is swiveled away from the base body, forms an angled swivel position () that deviates from the 90-degree position, and in that a backstop is assigned to the deburring blade (), which prevents it from swiveling back into the position in which it is swiveled at a 90-degree angle from the base body ().

Method for deburring the edges of intersecting boreholes, and tool for implementing the method

Miniaturized deburring and/or chamfering tool with a cylindrical guide sleeve () in which a blade holder base body () is arranged in an exchangeable manner, which has at least one receiving slot () for receiving and guiding a blade () arranged there, which is leaf-shaped and designed so that it can bend along its longitudinal axis, and which, at its free front end, has a cutting head () with a deburring or chamfering blade arranged there, wherein an internal cooling of the blade () and removal of shavings from the blade () are achieved by the fact that the coolant flows around the blade () in the receiving slot () on at least two facing sides.

Miniaturized deburring and/or chamfering tool with internal cooling

The invention relates to a deburring tool for deburring edges (), of any desired shape, of recesses in workpieces () using at least one cutting blade ('), wherein the deburring tool is in the form of a slotting and/or drawings tool which is rotated incrementally about its longitudinal axis and is driven displaceably in an oscillating manner in the direction of its longitudinal axis.
