Abstract
127,486. Gurmin, E. W. Oct. 21, 1918. Drills.-A depth-gauge for a drill, countersink, &c. comprises a tubular member f surrounding the drill b and rotatably attached, preferably adjustably as shown at g, to the end of a drill-spindle a, so that the member f ceases to rotate when in contact with the work. Preferably, a ball-bearing e is provided to take the thrust between the spindle a and the sleeve c. Slots h to facilitate the supply of lubricant may be provided.
