In a facet joint reamer with a shank and teeth at the distal end, the distal end is widened compared with the remainder of the shank.

Facet joint reamer

A method for manufacturing bone milling cutters, wherein a milling cutter toothing () is created at a distal face of a tubular milling cutter shaft () of a bone milling cutter at a given outer diameter (D) of the milling cutter shaft (). The following steps are carried out: determining the tube circumference (U) of the milling cutter shaft (); ascertaining an average desired tooth height (Hgew) of the milling cutter toothing (); 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).
