1. A cutting tool for cutting a notch within a side wall of a housing, the cutting tool comprising: a triangular cutting blade that extends outwardly from a central hub, the triangular cutting blade having a first edge that extends radially from the central hub, a second edge that is about as long as and is generally perpendicular to the first edge, and a third edge that is longer than the first and second edges and defines a right triangle with the first and second edges, wherein the second and third edges define a cutting portion, wherein when the second edge is brought in contact with the side wall, the cutting portion is positioned to cut the notch in the side wall, the notch having a well defined depth in accordance with a difference between a length of the third and second edges. 2. The cutting tool as recited in claim 1, wherein the cutting tool comprises four blades. 3. The cutting tool as recited in claim 2, wherein a triangular geometry of each of the four blades corresponds to an isosceles right triangle. 4. The cutting tool as recited in claim 1, wherein a length of a radius of the cutting tool is the distance from a center point of the central hub to a cutting point where the second edge connects to the third edge is approximately 1.41 times a length of the second edge. 5. The cutting tool as recited in claim 2, further comprising: a motor coupled to a cutting shaft and configured to drive the four blades at a predetermined rotational speed. 6. The cutting tool as recited in claim 1, wherein the housing is formed from a single piece of material. 7. A method for cutting a notch into a side wall of an electronic device housing using a cutting tool having a plurality of triangularly shaped blades each having a first edge that extends radially from a central hub, a second edge that is about as long as and is generally perpendicular to the first edge, and a third edge that is longer than the first and second edges and defines a triangle with the first and second edges, wherein the second and third edges define a cutting portion, the method comprising: bringing the second edge in contact with the side wall such that the cutting portion is positioned to cut the notch in the side wall; androtating the cutting tool such that the cutting portion cuts the notch into the side wall, the notch having a well defined depth in accordance with a difference between a length of the third and second edges. 8. The method as recited in claim 7, further comprising: subsequent to cutting the notch, reorienting the cutting tool such that the cutting tool is removable from the notch. 9. The method as recited in claim 8, further comprising: removing the cutting tool through the notch. 10. The method as recited in claim 7, wherein a cutting radius of the cutting tool is about 1.41 times a length of the second edge. 11. A cutting assembly for machining a notch into an interior surface of a housing formed from a single piece of metal, the cutting assembly comprising: a cutting tool, comprising: substantially triangular blades extending from a central hub, each of the triangular blades having a first edge that extends radially from the central hub, a second edge that is generally perpendicular to the first edge, and a third edge that defines a right triangle with the first and second edges, wherein the second and third edges define a cutting portion, wherein when the second edge is brought in contact with the interior surface, the cutting portion is positioned to cut the notch in the interior surface, the notch having a well defined depth in accordance with a difference between a length of the third and second edges, anda cutting shaft having an end coupled to a central portion of the central hub of the triangular blades and configured to rotate the triangular blades about an axis arranged along a longitudinal axis of the cutting shaft; anda fixturing device configured to secure the housing in place while the cutting tool performs a cutting operation within the housing. 12. The cutting assembly as recited in claim 11, wherein the cutting tool has a footprint that is relatively square. 13. The cutting assembly as recited in claim 11, wherein the cutting tool has a footprint and, in one orientation a geometry of the footprint is substantially the same as an opening in the housing. 14. The cutting assembly as recited in claim 11, wherein the blades are evenly spaced about the central hub. 15. The cutting assembly as recited in claim 11, wherein a depth of the notch is about 0.4 times the length of the second edge.
