    摘要: A method for manufacturing bone milling cutters, wherein a milling cutter toothing (12) is created at a distal face of a tubular milling cutter shaft (10) of a bone milling cutter at a given outer diameter (D) of the milling cutter shaft (10). The following steps are carried out: determining the tube circumference (U) of the milling cutter shaft (10); ascertaining an average desired tooth height (Hgew) of the milling cutter toothing (12); ascertaining the desired tooth period length (LZ′) of the milling cutter toothing from the desired tooth height (Hgew) at given parameters of a tooth period pattern; dividing the tube circumference (U) by the desired tooth period length (LZ); rounding the results to an even number value (Qz); and dividing the tube circumference (U) by the value (Qz) in order to obtain the tooth period length (LZ).
