The guided drill comprises a shank configured to be releasably mechanically associated with a contra angle hand piece, a guide body having an outer surface geometrically confined to a cylinder having a radius R1 so that the outer surface coincides with the cylinder at least along an areal section thereof, a stopper arranged between the shank and the guide body and a blade portion configured for drilling at a diameter smaller than 2*R1. The shank, the stopper, the guide body and the blade portion are integrally formed together from a hard alloy, rendering the guided drill reusable. A surgical kit is provided, comprising series of guided drills each guided drill having a different combination of a drilling diameter and a drilling length, a container containing the series of guided drills in a form of an array, and a chart comprising a map of the array and graphical indications.
