Abstract:
A tool includes a coupling, an inner adjustment sleeve, and an outer adjustment sleeve. The coupling connects a rotary tool to the inner adjustment sleeve. An adjustable portion of the inner adjustment sleeve is threadedly received in the outer adjustment sleeve. An offset aperture in the free end of the outer adjustment sleeve receives a tip of a valve stem for grinding. An optional cup at the end of the outer adjustment sleeve stabilizes the tool. A grinding bit with a shaft retained in a collet of the rotary tool is contained internally, in a channel, extending through the tool.

Claim (Index 11):
A grinding tool comprising:\n a coupler, a threaded sleeve and an alignment tube; the coupler including a first end, a second end and a coupler central channel extending from the first end of the coupler to the second end of the coupler, the first end of the coupler being open and including internal threads for connecting to a rotary tool, the second end of the coupler being open and opposite to the first end of the coupler; and the alignment tube including a first end, a second end and an alignment tube channel extending from the first end of the alignment tube to the second end of the alignment tube, and an alignment tube outer diameter, the first end of the alignment tube being open and including internal threads for connecting to the threaded sleeve, the second end of the alignment tube having an opening; the threaded sleeve including a central channel with a central longitudinal axis, and the threaded sleeve coupling the second end of the coupler to the first end of the alignment tube, a distance between the second end of the coupler and the first end of the alignment tube being adjustable by threadedly receiving a portion of the threaded sleeve in one of the central channel of the coupler and the channel of the alignment tube, and the; and the opening of the second end of the alignment tube having a center, and the central longitudinal axis of the threaded sleeve not being aligned with the center of the opening of the second end of the alignment tube, the coupler central channel, threaded sleeve central channel and alignment tube central channel being sized to receive a shank of a grinding disk assembly, with a disk of the grinding disk assembly being within the alignment tube adjacent to the second end of the alignment tube, and the outer diameter of the alignment tube being less than an inner diameter of a cup-shaped cam follower to be ground, and the grinding tool being separate from the cup-shaped cam follower to be ground, and the grinding tool being separate from the grinding disk assembly, and the grinding tool being separate from the rotary tool.
