Böni Knurling Tools function in a fundamentally different way than conventional knurling tools. The knurling wheels machine the workpiece tangentially 180° on opposite sides, so that there is no pressure on the work and cross ball-bearing spindles. The operating forces occurring are absorbed by the knurling tool, regardless of whether it is cutting or rolling. Depending on the quality of the material, we are able to cut or roll the knurl with the same tool.
