Abstract
A toothed tool body for a rotary drilling tool suitable not only for work normally performed with toothed roller bits or the like, but also advantageous in loamy or similar formations, has ribs extending peripherally between the teeth up to the tooth flanks and having a cross-section falling on both sides from a peak region, more particularly a roof-like cross-section. The peak region of the ribs is lower than the tips or edges of the teeth in the radial direction of the tool body.
