ABSTRACT:
A multiple spindle screw machine box tool insert holder, the box tool insert holder comprising: a shank member having a generally elongated parallel sided configuration including top and bottom elongated surfaces, and left and right elongated surfaces, the shank member also having from and rear opposing end surfaces; and an insert receiving pocket. The insert receiving pocket is positioned on the front end surface of the shank member. The insert receiving pocket is comprised of a bottom wall and three side walls for seating an insert therein. The insert has a central hole located therein. The side walls have a height less than a height of the insert. The insert receiving pocket has a threaded hole formed downwardly through the bottom wall. The threaded hole is non-concentric relative to a longitudinal central axis through the box tool insert holder, whereby when the insert is seated in the pocket a threaded pin member having a head on one end is adapted to engage the insert from above while the threaded pin member extends downwardly through the central hole in the insert and into the threaded hole in the bottom wall in threaded engagement, thereby securely holding the insert securely in place.
