Pressure-medium-controlled countersinking tool with one or more machining blades which are arranged in a rotatably driven base body and which can be actuated in their pivot position by supplying a pressure medium, wherein the actuation of the at least one blade takes place via at least one piston-cylinder unit actuated by the pressure medium, wherein the at least one blade is pivotably mounted on a bearing bolt forming a pivot axis and can be extended from a blade chamber arranged in the blade housing, wherein a centering device is arranged between the blade and the blade window of the base body in the radial distance from the pivot axis and in the pivot range of the at least one blade.

Pressure-medium-controlled countersinking tool with blade centering

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 (&#x2033;&#x2033;) 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 (&#x2033;&#x2033;) 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&#xb0; and 90&#xb0;, but preferably between 5&#xb0; and 45&#xb0; to the tool axis () and thus to the longitudinal axis () of the main borehole ().

Deburring tool for deburring transverse recesses that branch from a main borehole

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

A combined drill and chamfer tool () for producing boreholes () in a workpiece () and for subsequently producing a chamfer () on at least one bore edge of the borehole (), comprising a drill bit (), which is secured in a rotationally fixed manner in a base body (), and at least one chamfering blade () arranged behind the drill bit () in the axial direction, said chamfering blade being mounted in a blade window () arranged in the drill shank () and spring-loaded so as to be displaceable transversely to the longitudinal axis of the combined tool (), wherein the drill body () comprising the drill bit () and the drill shank () is made of a solid hard metal material, and wherein a spring-loaded, displaceable control bolt () is located in a central longitudinal bore () of the solid hard metal drill, the front tip () of said bolt controlling the transverse displacement of the chamfering blade (), which is transversely displaceable within the blade window ().

Combined drill and chamfer tool

Deburring blade for deburring bore margins with an even or uneven shape, having a base body () which is rotatably driven about its longitudinal axis, in which base body at least one bar blade () is held exchangeably in a spring-loaded, swivelably mounted blade holder () in the base body () in a radial bar blade bore () of the blade holder (), and the blade holder () is designed as an approximately cylindrical body, which is mounted rotatably in a bearing bore () of the base body ().

Deburring tool for deburring bore margins

A pressure medium controlled counterbore tool with one or multiple cutters for metal cutting, which can be actuated in their swivel position by supplying a pressure medium, wherein the actuation of at least one cutter is performed by at least one cutter by means of at least one piston-cylinder unit actuated by the pressure medium.

Pressure medium controlled counterbore tool with a piston-cylinder unit

A pressure medium controlled countersinking tool with one or more chip-removing knives, which can be activated by feeding in a pressure medium, in which for activation of at least one knife this is flowed in by a control medium.

Pressure-medium-controlled countersinking tool

A drilling tool cuffing insert adapted to be clamped in a rotatably driven drilling tool base body, the base body having a mounting groove formed in an end thereof defined by a pair of clamping jaws, each of the jaws having a bore therethrough, one of the bores being threaded, the bores for receiving a mounting screw for clamping said cuffing insert in the mounting groove, each of the jaws having a centering face, the cuffing insert comprising a plate-shaped cuffing element having a first end, a second opposite end, and a bore therethrough for receiving the mounting screw, the first end of the cuffing element having a pair of mutually opposing cuffing edges, the element having a chip face extending from each cuffing edge to the second end of the element, each of the chip faces having a centering fin with a centering face thereon, the cuffing element centering faces adapted to engage with the centering faces on the jaws of the base body to center the cuffing insert in the base body.

Drill plate with a clamping attachment in a base body

The invention describes a drill plate with a clamping attachment in a rotatably driven base body, which on one of its end faces forms a centering groove that is open towards the top. A clamping slot extending into the material of the base body is arranged at the bottom of the centering groove. The centering groove is bounded by at least two opposing mounting jaws, with at least two diametrically opposing stop faces arranged in the region of the clamping jaws for providing centering contact with the drill plate. The clamping attachment is formed by a mounting screw which clamps the drill plate in the centering groove. To improve transfer of the operating torque from the drill plate to the base body and to facilitate handling, at least two centering fins that are diametrically opposed with respect to the transverse center axis are arranged on the drill plate. The centering fins contact corresponding stop faces disposed on the corresponding clamping jaws of the base body.
