ELLIPTI-BUR: UNIFORM DEBURRING OF ELLIPTICAL BORES
The solution for fast & thorough deburring of elliptical bores
All important tool parts are hardened. The cutting part, which has two crosswise opposing cutting edges, is made of hardened high-speed steel. An additional surface treatment guarantees an even longer tool life. The Ellipti-Bur is designed so that the low-cost blade can be easily replaced if necessary.
The Ellipti-Bur consists of a spring-loaded as well as a self-steering conical drill head that precisely positions the tool to achieve optimal and consistent results. In use, the Ellipti-Bur is first centred over the Bore to be deburred. As soon as the tool is moved forward, the drill head is pressed back into the shaft against the spring so that the cutting edge comes into contact with the edge of the drill bore.
By moving the rotating tool (in the working feed) to countersinking depth and a short dwell time, the bore hole is deburred uniformly. Due to the spring-loaded cutting edge, it centres itself flexibly in axial as well as radial direction on the bore edge and almost evenly approaches it.
