Abstract
The cutting head of a boring tool has a cylindrically arcuate face about the axis of rotation and a radially and axially open groove for release of cooling fluid and chip removal. A single cutting plate is releasably recessed in one wall of the groove and a clamping jaw in the other wall in abutting engagement with the blade whose edge has a primary cutting portion axially projecting from an end portion of the cutting head and a secondary cutting portion radially projecting from the arcuate carrier face.
