Abstract
The invention relates to a reaming tool, comprising a rotationally drivable main body (16) and at least one cutting body (18) fastened thereto. The at least one cutting body has at least one reaming blade (26) at the edge of a rake face (28). According to the invention, a chip-forming step (32) and/or chip-breaking elements (34) are formed in the rake face (28) and the reaming blade (26) has a ground cutting edge (40, 42, 44).
Claims14
-15. (canceled)
A reaming tool, having a rotationally drivable main body (16) and at least one cutting body (18) fixed thereto that is configured as a primary shaping part and has at least one reaming cutter (26) on the edge of a rake face (28), wherein the reaming cutter (26) has a ground cutting edge (40, 42, 44) characterized in that the rake face (28) has a positive rake angle in the range from 5° to 10° and that raised chip-breaking elements (34) are formed in the rake face (28) as primary shaping parts.
A method for producing a reaming tool (10), in particular as claimed in claim 1, in which method at least one cutting body (18) is attached to a rotationally drivable main body (16), and at least one reaming cutter (26) is formed on the edge of a rake face (28) of the cutting body (18), characterized in that raised chip-breaking elements (34) are preformed as primary shaping elements on the rake face (28) which has a positive rake angle in the range from 5° to 10°, and in that subsequently the reaming cutter (26) is formed at least in some sections by material removal.
