A quick release attachment for a power tool having a rotatable spindle includes a pad assembly and a quick release connector adapted to join the pad assembly to the spindle. The pad assembly includes a mounting plate and a pad affixed to at least one side of the mounting plate, wherein the pad includes a primary material that is either metal, stone, ceramic, fiber, sand, nylon or polypropylene, and the mounting plate includes a central aperture. The mounting plate aperture further comprises a circular ring disposed therein and has a t-shaped key extending diametrically across the aperture. The t-shaped key comprises a magnetically attractive material. The quick release connector has a main body adapted to fixedly engage the spindle. The connector further has a head end extending from the main body and having a circular cross-section sized to engage the circular ring. The head end further has a slot sized to engage the t-shaped key. The slot further comprises a distal portion extending axially along the head end, a proximal portion extending axially along the head end offset from the distal portion, and a transition portion joining the distal and proximal portions. The main body further comprises a permanent magnet disposed therein having at least one surface adjacent to the proximal portion of the slot. The pad assembly is selectively affixed to the quick release connector by manipulating the head end into the aperture and moving the t-shaped key through the slot until reaching the proximal portion, whereupon the t-shaped key is retained by the magnetic attraction of the permanent magnet.

1. An attachment system for a power tool, comprising: an abrasive pad assembly having a mounting plate, a key, and at least one abrasive pad affixed to a side of the mounting plate, the mounting plate having a central aperture and a circular ring disposed therein, wherein the at least one abrasive pad comprises at least one abrasive outer surface configured to come into contact with an external object, and the key is connected to the circular ring, extends diametrically at least partially across the aperture, comprises a magnetically attractive material, and is located entirely below the at least one abrasive outer surface, thereby preventing the key from coming into contact with the external object; anda connector, which is separate and distinct from the abrasive pad assembly, having a main body adapted to fixedly engage a spindle of the power tool, the connector further having a head end extending from the main body and having a circular cross-section sized to engage the circular ring, the head end further having a slot sized to engage the key, the slot further comprising a distal portion extending axially along the head end, a proximal portion extending axially along the head end offset from the distal portion, and a transition portion joining the distal and proximal portions, the main body further comprising a permanent magnet disposed therein having at least one surface adjacent to the proximal portion of the slot and the main body of the connector having a circular cross-section that is larger in diameter than the circular cross-section of the head end of the connector, and includes a shoulder at the intersection of the main body of the connector and the head end of the connector;wherein, the abrasive pad assembly, including the mounting plate, the key and the at least one abrasive pad, is selectively affixed to the connector by manipulating the head end into the circular ring and moving the key through the slot until reaching the proximal portion such that the circular ring comes into contact with the shoulder of the main body, whereupon the key is retained by the magnetic attraction of the permanent magnet and the shoulder supports the abrasive pad assembly via the circular ring. 2. The attachment system of claim 1, wherein the transition portion of the slot further comprises an arcuate opening on opposite sides of the head end providing transition path for the key as it traverses the distal and proximal portions of the slot. 3. The attachment system of claim 1, wherein the circular ring further comprises exterior ridges providing a frictional engagement with the aperture. 4. The attachment system of claim 1, wherein the circular ring is removably affixed to the aperture of the mounting plate. 5. The attachment system of claim 1, wherein the proximal portion of the slot is offset from the distal portion of the slot by approximately 90°. 6. The attachment system of claim 1, wherein the at least one abrasive pad further comprises at least a material selected from a list of materials consisting of metal, stone, ceramic, fiber, sand, nylon and polypropylene. 7. The attachment system of claim 1, wherein the key is comprised of steel. 8. The attachment system of claim 1, wherein the connector main body has an interior surface adapted to threadingly engage the spindle of the power buffer. 9. The attachment system of claim 1, wherein the ring further comprises a circular non-threaded opening. 10. The attachment system of claim 1, wherein the connector main body further comprises opposed surface regions oriented for engagement by a tightening tool. 11. The attachment system of claim 1, wherein the connector main body is comprised entirely of parts that do not move relative to one another. 12. The attachment system of claim 1, further comprising the power tool having a spindle configured to rotate in a first direction during operation of the power tool, wherein the transition portion of the slot provides a direction path for removal of the key from the slot that is opposite to the first direction, thereby precluding inadvertent removal of the abrasive pad assembly from the connector during operation of the power tool. 13. An attachment system for a power tool, consisting of: an abrasive pad assembly having a mounting plate, a key, a first abrasive pad affixed to a first side of the mounting plate, and a second abrasive pad affixed to a second side of the mounting plate, the mounting plate having a central aperture and a circular ring disposed therein, wherein the first and second abrasive pads include first and second abrasive outer surfaces configured to come into contact with at least one external object, and the key is connected to the circular ring, extends diametrically at least partially across the aperture, comprises a magnetically attractive material, and is located entirely between the first and second abrasive outer surfaces, thereby preventing the key from coming into contact with the at least one external object; anda connector, which is separate and distinct from the abrasive pad assembly, having a main body adapted to fixedly engage a spindle of the power tool, the connector further having a head end extending from the main body and having a circular cross-section sized to engage the circular ring, the head end further having a slot sized to engage the key, the slot further comprising a distal portion extending axially along the head end, a proximal portion extending axially along the head end offset from the distal portion, and a transition portion joining the distal and proximal portions, the main body further comprising a permanent magnet disposed therein having at least one surface adjacent to the proximal portion of the slot and the main body of the connector having a circular cross-section that is larger in diameter than the circular cross-section of the head end of the connector, and includes a shoulder at the intersection of the main body of the connector and the head end of the connector;wherein, the abrasive pad assembly, including the mounting plate, the key, the circular ring, and the first and second abrasive pads, is selectively affixed to the connector by manipulating the head end into the circular ring and moving the key through the slot until reaching the proximal portion such that the circular ring comes into contact with the shoulder of the main body, whereupon the key is retained by the magnetic attraction of the permanent magnet and the shoulder supports the abrasive pad assembly via the circular ring. 14.
