ABSTRACT:
A drilling device for drilling blind holes to a preselected depth in a work piece is provided. The drilling device includes a drill which rotatably drives a spindle which spindle drives a drill bit. Guide means for mounting the drill member for axial movement to perform the drilling operation are provided. A rod member is secured to and extends from the drill member and is moveable axially therewith as the drill performs its drilling function. An adjustable member is threadably mounted on the rod and is moveable relatively axially on the rod. Adjusting means including a wheel and detent are provided which are connected to the adjustable member and the rod member to rotate the adjustable member with respect to the rod member to thereby cause relative axial movement of the rod member and adjustable member which will change the relative position of the adjustable member on the rod member. Actuating means are also provided which are selectively connectable to the adjustable member to reciprocally drive the adjustable member between a retracted position and a fully actuated position to thereby provide a drive actuation for the drill. Hence the relative movement of the adjustable member, the rod member will change the fully actuated position of the drill bit upon actuation irrespective of the position of the actuating member.
