Abstract:
1. Cutting tooth for a trench wall cutter, the cutting tooth having opposed cutting directions and a primary plane of symmetry approximately perpendicular to the opposed cutting directions and comprising: a tongue-shaped tooth base for reception in a cutting wheel, wherein the tongue-shaped tooth base has a head-side and a circumferentially surrounding holding groove, and at least two cutters arranged on the tooth base opposite each other at the head-side of the tooth base on opposite sides of the primary plane of symmetry, wherein the cutting tooth has a mirror symmetric configuration with respect to the primary plane of symmetry, wherein: the cutting tooth has at least one head-side W-shaped profile, which extends across the at least two cutters, the plane of symmetry of the cutting tooth runs through a center vertex of the at least one head-side W-shaped profile, the outer flanks of the at least one head-side W-shaped profile are formed by the at least two cutters, and the at least two cutters are each configured as double cutters with parallel cutting edges, and the double cutters have, when seen perpendicular to the plane of symmetry, a W-shaped profile.
