A drilling and milling guide for interchangeably accommodating for example, powered hand drills or milling machines, with the guide including a machine support adapted to be displaced along two parallel guide columns against a readjusting spring force, and a bottom plate at which the guide columns are pivotally mounted, with the bottom plate being provided with a central opening for accommodating different machine types and in order to enable the installation of adjustable guide stops, ends of the readjusting spring, not attached to the machine support, are fixed at a separate abutment which is adapted to be displaced and fixed along the guide columns. The bottom plate is provided with two parallel channels disposed in a plane parallel to the bottom plate for accommodating two guide rods which support a guide stop. Each of the channels pass near the guide columns and vertically through a plane extending through both guide columns.
A drilling and milling guide for interchangeably accommodating power tools, the guide comprising a bottom plate, a pair of spaced parallel guide columns, means for pivotally mounting the guide columns on the bottom plate, a machine support means displaceably mounted on said guide columns, a pair of vertically extending lug means provided at said machine support means and mounted on said guide columns, each of the lug means includes a chamber means and each of the guide columns passes through a respective one of said chamber means, a pair of spring means for normally urging the machine support means in a direction away from the bottom plate, each of the spring means are respectively mounted within one of said chamber means, a first end of each of the spring means abutting a first portion of the respective chamber means, a pair of abutment means interposed between a second end of each of said spring means and an opposite portion of the chamber means and displaceably mounted on said guide columns, means for enabling a fixing of the abutment means at an adjusted position along the guide columns, and an opening provided in a central area of the bottom plate for accommodating a tool.
