In a following second longitudinal section, a secondary flank circumferentially adjoins the secondary cutting edge.

Drill

An interface element between a first tool element and a second tool element includes a projection on one of the first and second tool elements and a cavity that receives the projection on the other of the first and second tool element. The cavity includes inner contours which are designed to receive polygonal and/or stellate projections.

Interface element

The present disclosure relates to an expandable reamer having a base body, a ring section, at least one cutting edge which is geometrically defined and provided on the outer surface of the ring section, an adjustment device which works on the ring section from the inside, has an adjustment screw, and serves to adjust the radial position of the at least one cutting edge, wherein the adjustment device is arranged in a cavity provided in the base body of the expandable reamer, and an adjustment body with a conical or round outer surface. The adjustment body can be displaced in the direction of the central axis of the expandable reamer and serves for the expansion of the ring section. The expandable reamer is characterized in that the adjustment body is designed as an adjustment sleeve which surrounds the adjustment screw and is mounted in a floating manner.

Expandable reamer

A tool for the machining of workpiece surfaces includes at least one adjustable, geometrically defined cutting edge. The tool additionally includes an adjusting device for the adjusting of the distance of the cutting edge to the central axis of tool. The adjusting device has a drive shaft that acts on an adjusting slide via a gearbox, which determines the distance of cutting edge from the central axis of tool. The adjusting slide may be a round slide arranged eccentrically to the central axis of tool. The gearbox may have a high reduction and may directly act on the adjusting slide.
