ABSTRACT:
The wood plug trimmer is a devise used in conjunction with a hand held grinder that permits expeditious trimming of wooden plugs that are used to cover screws in wooden objects. The wood plug trimmer will have an interior cylindrical shape that will slide over the shank of a hand held grinder. The interior diameter of the wood plug trimmer will be slightly smaller than the exterior diameter of the shank of the hand held grinder and slightly shorter in length than the length of the base of the shank of the hand held grinder to the tip of the grinding die. This will permit the wood plug trimmer to be adjusted so that the grinding die will be flush with the wood surface. The wood plug trimmer will have a plurality of pilot/waste ports that will be wider than the wooden plugs to be trimmed. When in place the wood plug trimmer will have the wood plugs pass through the pilot/waste ports and permit the grinding die to trim the wooden plug flush with the surface. This will eliminate the need for hand tools and expeditiously and safely permit the removal of the excess wood plugs.
