A tool interconnect structure includes a spindle adapter, a rotary cutting tool, and a lock mechanism securing the rotary cutting tool to the spindle adapter. The spindle adapter has a face with a short hollow tapered shank at the face. The rotary cutting tool has a face for engaging the spindle adapter face and a tapered recess at the face for cooperating with the tapered shank. The lock mechanism includes a pair of blocks having shoulders at their ends adapted to engage annular grooves within the hollow tapered shank and within the rotary cutting tool. The blocks have threaded apertures therethrough and a screw having oppositely threaded end portions extends through the apertures. Rotation of the screw causes the shoulders to engage with and disengage from the grooves.
