Abstract
Apparatus for inserting Tee-nuts in a solid wooden workpiece, the Tee-nuts having flanges and threaded sleeves of predetermined length, the workpiece having a thickness greater than the sleeve length. The apparatus has an anvil, an anvil die supported on the anvil, a through bore in the anvil die extending along an axis normal to the anvil, and a circular cutting edge. A power operated device is mounted so as to be reciprocable towards and away from the anvil. A moveable die is mounted on the reciprocable device in registration with the anvil die. The movable die includes a stub portion which can be slidingly received in the threaded sleeve of a Tee-nut, and which registers co-axially with the through bore in the anvil die. The anvil die is generally frusto-conical and has two outer surface portions meeting at an obtuse angle.
