This invention relates to an improvement in milling-tools especially designed for milling-followers in locks, but applicable for other purposes, the object being the construction of a longitudinal cutter, easily adjustable to be ground or sharpened without removing from the holder and it consists in the arrangement of a cutter in a longitudinal groove formed in a spindle, and around the said spindle an internally-threaded sleeve, with corresponding threads in the cutter, so that by turning the sleeve the cutter may be thrown out or drawn in, as the case may be.
