Adjustable diameter hole cutter

A hole cutter assembly operable to cut a plurality of different sized diameter holes in a work piece, the hole cutter assembly comprising:

• an arbor configured to connect to a power tool for rotation about an axis;
• a body coupled to the arbor for rotation with the arbor;
• a first arm moveably coupled to the body, the first arm extending generally perpendicular to the axis;
• a first cutting blade coupled to the first arm and moveable with the first arm relative to the body;
• a second arm moveably coupled to the body, the second arm extending generally perpendicular to the axis;
• and
• a second cutting blade coupled to the second arm and moveable with the second arm relative to the body;
• wherein the first arm and the second arm are oriented generally parallel to each other on opposing sides of the axis.

An adjustable hole cutter system operable to cut a plurality of different sized diameter holes in a work piece, the adjustable hole cutter system comprising:

• a debris shield assembly including
• a bowl, and
• a hub slidably coupled to the bowl;
• and
• a hole cutter assembly substantially received within the debris shield assembly, the hole cutter assembly rotatable relative to the debris shield assembly, the hole cutter assembly including
• an arbor extending through the hub and configured to connect to a power tool for rotation about an axis,
• a body coupled to the arbor for rotation with the arbor, the body defining an aperture that selectively receives the drill bit,
• a drill bit removably received in the aperture of the body for rotation with the arbor,
• a first arm moveably coupled to the body, the first arm extending generally perpendicular to the axis,
• a first cutting blade coupled to the first arm and moveable with the first arm relative to the body,
• a second arm moveably coupled to the body, the second arm extending generally perpendicular to the axis, and
• a second cutting blade coupled to the second arm and moveable with the second arm relative to the body;
• wherein the first arm and the second arm are moveable relative to the body to adjust a cutting diameter of the hole cutter assembly when the drill bit is not received within the aperture, and wherein the first arm and the second arm are fixed relative to the body when the drill bit is received within the aperture.
