Reversible flange assembly for power tools

A retention flange for a power tool comprising:

• a body defining a pass-through aperture configured to accommodate an output spindle rotatably driven by an electric motor of the power tool, the body comprising a first face and a second face that is opposite the first face,
• wherein the first face of the body defines an engagement interface, the engagement interface being geometrically shaped to selectively engage, one at a time:
• a mounting aperture of a dynamic working tool, wherein engagement between the engagement interface and the mounting aperture rotationally fixes the dynamic working tool to the retention flange;
• and
• a transfer component comprising a spindle engagement interface configured to engage the output spindle and rotationally fix the transfer component to the output spindle, wherein engagement between the engagement interface and the transfer component rotationally fixes the retention flange to the output spindle.

A power tool comprising:

• a housing;
• an electric motor housing within the housing;
• an output spindle rotatably driven by the electric motor;
• a transfer component having a pass-through aperture through which the output spindle extends and a spindle engagement interface configured to engage the output spindle and rotationally fix the transfer component to the output spindle;
• and
• a reversible retention flange having a through-hole for the output spindle, the flange comprising opposing first and second faces, each with a distinct engagement interface, wherein:
• the first face is configured to selectively engage, one at a time, a first dynamic working tool with a first-sized mounting aperture and the transfer component, and
• the second face is configured to selectively engage, one at a time, a second dynamic working tool with a second-sized mounting aperture, different from the first, and the transfer component,
• whereby the reversible retention flange is operable to accommodate dynamic working tools with a mounting aperture of either the first size or the second size.

A transfer component for a power tool comprising:

• a body defining a pass-through aperture configured to accommodate an output spindle rotatably driven by an electric motor of the power tool;
• a spindle engagement interface disposed on the body and configured to engage the output spindle to rotationally fix the transfer component to the output spindle;
• a first engagement surface on the body configured to engage a first retention flange, the first retention flange being configured to engage a first dynamic working tool on a side opposite the engagement with the transfer component;
• and
• a second engagement surface on the body, axially offset from the first engagement surface, configured to engage a second retention flange, the second retention flange being configured to engage a second dynamic working tool on the side opposite the engagement with the transfer component.
