Abstract

See full text

A device for calibrating a drill bit of a chuck includes an intermediate sleeve including two rear curved elements, a front shoulder, internal threads rearward of the shoulder, and an externally threaded extension projecting out of a front end; a front window including a diametrical calibrating line; an externally threaded rim secured to the internal threads to urge the window against the shoulder; and a ring having internal threads secured to the extension. A fastening of the chuck and the device, a loosening of the retainer ring, and a rotation of the rear holding member to rotate the drill bit can align the drill bit with the calibrating line.
