Abstract: An auger system for removing material from around an object without damaging the object. The inventive device includes a tubular auger attachable to a drive unit, and an insert member insertable within the upper opening of the valve casing. The tubular auger is comprised of a plurality of mill teeth attached to the lower portion of the tubular auger. The tubular auger includes an auger lumen that is positionable about the valve casing during cutting. The insert member is comprised of lower portion that is positionable within the casing lumen of the valve casing, and an outer portion that has an outer diameter approximately the same as the outer diameter of the valve casing for guiding the tubular auger and for preventing debris from entering the valve casing. The insert member preferably includes a handle for allowing insertion and removal from the valve casing.
