Abstract
A rotary surgical tool includes a driving shaft. A cutting head, connected to the driving shaft, is configured to cut into a surface. Driving means, connected to the driving shaft, rotate the driving shaft and the cutting head. A depth-limiting feature includes an adjustable stud extending from one of the cutting head and the surface toward the other one of the cutting head and the surface. The stud has a protrusion length that is greater than and/or equal to the length of a desired amount of final penetration of the cutting head into the surface. An aperture, provided in the other one of the cutting head and the surface, has an aperture depth that is greater than and/or equal to the desired amount of final penetration of the cutting head into the surface. Interaction between the aperture and the stud limits longitudinal advancement of the cutting head into the surface.
