The flow rate of the cutting fluid depends on the internal profile and the length of the drill-shaft· The cross-sectional area of the shaft also determines its stiffness and breaking strength. Tool wear increases the cutting forces and thereby also the stressing of the drill. Optimisation of the progress-integrity can be achieved by careful selection of the cutting-parameters.eninfo:eu-repo/semantics/openAccessTieflochbohren , Bohrwerkzeug670article
