A reaming tool, having a rotationally drivable main body () and at least one cutting body () fastened thereto. The at least one cutting body has at least one reaming blade () at the edge of a rake face (). A chip-forming step () and/or chip-breaking elements () are formed in the rake face () and the reaming blade () has a ground cutting edge ().

Reaming tool and method for the production thereof

A solid drill bit for machine tools has a drill bit body and two indexable inserts arranged at a radial distance from one another in respective insert seats. The inserts have an essentially quadratic contour. Their front-end main cutting edges project axially beyond the drill bit body and radially overlap one another. The outer insert has an outer insert corner and a secondary cutting edge perpendicular to the main cutting edge that projects radially beyond the circumference of the drill bit body. To permit burr-free through-drilling, the main cutting edge of the outer insert is subdivided in its longitudinal extent into a radially inner working section and a rectilinear peeling section adjoining the working section and extending to the outer insert corner. The sections enclose a setting angle of 95&#xb0; to 120&#xb0;. The peeling section is set at a positive setting angle of 72&#xb0; to 87&#xb0;.
