A tufting tool module () for a tufting machine is provided. The tufting tool module comprises a plurality of tufting tools (). The tufting tools have a head portion and a securing portion. The securing portion of each tufting tool is casted in a base block (). The securing portions of each tufting tool is provided with at least two cut outs () located inside the base block. By providing such cut outs it is possible to reduce the lateral pressure differences between the different tufting tools of the tufting tool module during casting of the base block. This is because the cast material, such as zinc, is allowed to move more freely within the cast during casting of the base block. Furthermore, the cut outs will during the cooling phase of the metal, e.g. zinc, control and stabilize the shrinkage so the tufting tools will not be dislocated. In other words, dislocation of the tufting tools during the casting process can hereby be reduced or eliminated. The result is a tufting tool module with improved tolerances.
