Abstract
The invention relates to a cutting element for a hollow drill comprising a cutting area and an essentially cylindrical area. The essentially cylindrical area has recesses, which are arranged on the inside at regular intervals and open toward the cutting area. In one embodiment of the invention, the recesses extend in an axial direction while being arranged in an interspaced manner preferably in the peripheral direction. The recesses arranged at regular intervals in the peripheral direction produce a geometric shape that is generally described as a polygon. The invention also relates to a cutter support and to a hollow drill. The cutting element is connected to the cutter support via a clamping connection preferably in a manner that enables the cutting element to be detached.
Claims29
-28. (canceled)
A cutting element for a hollow drill, with a cutting region and with an essentially cylindrical region, wherein the essentially cylindrical region has on the inside depressions arranged preferably at regular intervals and opening in the direction of the cutting region.
The cutting element as claimed in claim 44, wherein the depression or recess has an essentially triangular contour.
The cutter support as claimed in claim 19, characterized by at least one perforation through which at least one tab of the cutting element can be acted upon with an unlocking force.
A hollow drill comprising
- a cutting element having a cutting region and an essentially cylindrical region, wherein the essentially cylindrical region has on the inside depressions arranged preferably at regular intervals and opening in the direction of the cutting region;
- and
- a cutter support wherein the cutting element and cutter support are produced as separate components, the cutter support having an orifice for receiving the cutting element, and characterized by a conically designed region, in which the cone angle opens in the opposite direction to the orifice for the cutting element, and elevations for receiving the depressions of the cutting element.
