A tool interconnect structure includes a spindle adapter, a rotary cutting tool, and a lock mechanism securing the rotary cutting tool to the spindle adaptor. The spindle adapter has a face and a short hollow tapered shank at the face. The rotary cutting tool has a face for engaging the spindle adaptor face and a tapered recess at the face for cooperating with the tapered shank. The lock mechanism includes a first retention stud secured within the tapered recess, a second retention stud secured within the tapered shank, first and second lock elements located within the hollow tapered shank and on opposite sides of the retention lugs, and a universal screw extending through the lock elements for selectively interconnecting the locking elements with the first and second retention studs. The retention studs and the locking elements have cooperating wedges for generating both a push-on force for obtaining full-face contact between the rotary cutting tool and the spindle adaptor and a pull-off force for separating the tapered recess from the tapered shank.
A tool interconnect structure comprising a spindle adapter having a tapered shank, said tapered shank having a length of less than {fraction (7/16)} inch, a rotary cutting tool having a tapered recess sized and shaped for cooperating with said tapered shank, and a lock mechanism securing said tapered shank within said tapered recess.
A rotary cutting tool comprising a body adapted for rotation about a longitudinal axis, said body forming a face substantially perpendicular to said longitudinal axis and a tapered recess at said face and substantially coaxial with said longitudinal axis, said tapered recess having a longitudinally extending retention stud secured thereto.
A tool interconnect structure comprising a spindle adaptor, a rotary cutting tool, one of said adaptor and said rotary cutting tool having a tapered shank and the other having a tapered recess cooperating with said tapered shank, and a lock mechanism securing said tapered shank in said tapered recess, said lock mechanism including a first retention stud secured within said tapered recess and at least one lock element within said tapered shank and selectively interconnecting with retention stud.
A tool interconnect structure comprising a spindle adapter having a hollow tapered shank, a rotary cutting tool having a tapered recess sized and shaped for cooperating with said tapered shank, and a lock mechanism securing said tapered shank within said tapered recess, said lock mechanism including a first retention stud secured within said tapered recess, a second retention stud secured within said tapered shank, first and second lock elements within said hollow tapered shank and on opposite sides of said retention lugs, and an actuator for selectively interconnecting said locking elements with said first and second retention studs.
