Adapter for coupling an accessory tool to a drive member of a power tool

An adapter for coupling an accessory tool to any of a plurality of power tools, each of said plurality of power tools having a distinct tool drive structure in comparison to tool drive structures of the rest of said plurality of power tools, said adapter comprising a body that includes:

• a first side surface,
• a second side surface positioned opposite to said first side surface,
• an inner peripheral surface extending from said first side surface to said second side surface, said inner peripheral surface defining a central opening,
• an outer peripheral surface extending from said first side surface to said second side surface,
• wherein said first side surface has defined therein a plurality of recesses positioned around said central opening,
• wherein said body has a first adapter drive structure and a second adapter drive structure,
• wherein said first adapter drive structure defines a first plurality of recesses of said plurality of recesses positioned around said central opening and said second adapter drive structure defines a second plurality of recesses of said plurality of recesses positioned around said central opening, each of said second plurality of recesses being non-contiguous with each of said first plurality of recesses,
• wherein said first adapter drive structure and said second adapter drive structure each possesses a distinct configuration in comparison to each other,
• wherein said first adapter drive structure is configured to mate with a first tool drive structure of a first power tool of said plurality of power tools, and
• wherein said second adapter drive structure is configured to mate with a second tool drive structure of a second power tool of said plurality of power tools, and
• wherein at least a single one of said second plurality of recesses of said second adapter drive structure is disposed immediately adjacent to and between two of said first plurality of recesses of said first adapter drive structure.
