Patent abstract
A grinding system including a pilot bit and a base having teeth extending from the base. The pilot may have a tapered cross-section, threads to control the rate at which it engages an object and a flute to facilitate the removal of material of an object. A method of using the device may include allowing the bit and the base to work together in a manner that the portions of the system engage an object at a similar rate.
